the short version
best overallZernioproducts connecting many social accounts, where per-profile pricing would kill margins90/100runner-upBuffer APIthe best risk-adjusted starting point for anything you intend to keep running88/100

the defining fact of this market is the gap between 'the api is free' and 'you can actually use it'. meta, linkedin, tiktok and reddit all charge nothing and are all harder to get into than x, which charges real money. that inversion is the whole reason the aggregators in the first half of this list can charge $30 to $600 a month — you are not paying for http calls, you are renting their partner approvals.

so this ranking mixes two things on purpose: unified aggregators that give you one api across many networks, and the first-party platform apis they sit on top of. for a developer choosing where to spend a week, those are genuinely the same decision.

three numbers that dominate search results are wrong, and we've corrected them here. the widely-quoted entry price for the biggest aggregator is roughly a sixth of its real one. one popular platform's own pricing table implies api access is a premium feature when its docs say it's on every paid plan. and youtube's quota is no longer a flat daily unit budget — search and upload were carved out into separate allowances, which changes the maths for anything that publishes.

if you are building an agent, mcp support has gone from nonexistent to a checkbox that separates viable from not in about eighteen months. x, buffer, ayrshare, blotato, postiz, mixpost and several newcomers all ship one. hootsuite, sprout social, publer and socialbee do not, and for agent work that is now a reason to mark a vendor down.

    Zernio

    formerly Late — graduated per-account pricing that beats everyone at scale

    90/100

    verdictthe best price-to-capability ratio in the category by a wide margin, with a real free tier and webhooks included from the start.

    pricing is graduated by account count: free for two, $6 each for three to ten, $3 up to a hundred, and $1 beyond that with no cap and no sales call. unlimited posts, analytics, messaging, comments, ads and webhooks are included at every tier. at fifty connected accounts that is an order of magnitude below the per-profile incumbents.

    note the rebrand, because it makes most existing coverage stale: late became zernio in 2026 and getlate.dev now redirects. the sdks renamed too — the node and python packages and the cli all moved namespace — but api endpoints, keys and webhooks are unchanged, with a six-month grace period on the old packages.

    x costs are passed straight through at x's own per-request rates rather than absorbed, which is now standard across aggregators and is a real budgeting trap if you post links.

    the risk is company maturity. it is young, visibly founder-led, and has just been through a rebrand. that is a genuine concentration risk for something you build a product on, and it is the main reason to weigh buffer's stability against zernio's economics.

    pros
    • +graduated pricing is 10–25× cheaper than per-profile rivals at scale
    • +genuine free tier with webhooks included
    • +unlimited posts, analytics, messaging and ads at every tier
    • +sdk rename was backwards-compatible with a six-month grace period
    cons
    • young company with a recent rebrand — dependency risk
    • x/twitter costs passed through, not absorbed
    • platform count is stated inconsistently across its own marketing

    Buffer API

    a free-tier api and an official mcp server, from a company that will still exist next year

    buffer reopened as a real developer platform: self-serve keys from your account settings, bearer auth, and endpoints for channels, posts, ideas and metrics. api access works on the free plan, which almost nothing else here offers.

    the rate-limit design is the best in this ranking and it is worth copying. three rolling windows — fifteen minute, twenty-four hour and thirty day — and when you exceed one, the 429 response tells you which window you exhausted and includes a retry-after header. most first-party platform apis just say no.

    the official mcp server documents support for claude, chatgpt, cursor, raycast and perplexity, and there is a cli. for agent work this is one of the more thoughtfully built offerings from an established vendor.

    the ceiling is the catch. three thousand posts a month on free and fifteen thousand on team is low for a multi-tenant product, and analytics depth trails the specialists. higher limits exist by emailing them, which is not a plan you can budget against.

    pros
    • +api and mcp server available on the free plan
    • +best rate-limit ergonomics here — named window plus retry-after
    • +mature, stable company with a decade of track record
    • +buffer carries the platform oauth and approval burden
    cons
    • 30-day rolling caps are low for multi-tenant products
    • publishing-focused; analytics thinner than rivals
    • higher limits require emailing support

    ayrshare covers more ground than anyone else: posts, analytics, comments, messages and ads across thirteen networks, with user profiles that abstract away per-platform oauth so you never register apps for each end user.

    correct the price before you plan around it. software directories widely list this as starting around $25 a month; ayrshare's own pricing page says $149 for a single profile, $299 for up to ten and $599 for thirty, with per-profile overages above that. the cheap figure appears to be copied between listing sites.

    rate limits are documented properly — three hundred requests per five minutes per user profile, with headers to track it — and unusually, they publish the consequence of ignoring them: a thousand 429s in twenty-four hours suspends the profile.

    there are two mcp servers, one read-only for documentation and code generation and one for runtime actions. per-profile pricing is the structural problem: for a multi-tenant saas with many end users, this model gets expensive faster than almost any alternative here.

    pros
    • +widest capability surface — publishing, analytics, comments, dms, ads
    • +handles per-user oauth so you don't register platform apps
    • +two mcp servers, including one for documentation
    • +documented rate limits and an explicit suspension policy
    cons
    • $149/month for one profile is steep for indie developers
    • per-profile pricing punishes multi-tenant products
    • messaging and ads coverage is narrower than the marketing suggests

    Postiz

    open source, self-hostable, api on the cheapest tier

    84/100

    verdictthe best open-source option, and one of very few that puts the api and webhooks on the entry tier rather than behind an enterprise plan.

    teams who want no vendor lock-in and are willing to run it themselves

    postiz is agpl-licensed and self-hostable, with a cloud tier from $29 a month. crucially the public api and webhooks are available on every tier including the cheapest — publer, metricool and sprout all gate api access behind their top plans.

    there is an official mcp server, a node sdk and an n8n node, and development is very active.

    two things to understand before committing. the agpl is a real constraint if you plan to build a commercial hosted product on a modified version — take advice rather than assuming. and self-hosting does not exempt you from platform-side approval: you still need your own tiktok audit, your own meta app review, your own linkedin partner status. that is the single most common misconception about self-hosted schedulers, and it is usually the hardest part of the whole project.

    cloud channel caps are low relative to the graduated-pricing competitors, so at scale the self-hosted path is the one that makes sense.

    pros
    • +api and webhooks on the $29 entry tier
    • +fully self-hostable with no vendor lock-in
    • +official mcp server, node sdk and n8n node
    • +very active development
    cons
    • agpl is a genuine constraint for commercial embedding
    • self-hosting means you own every platform approval yourself
    • cloud channel caps are low relative to rivals

    Blotato

    flat pricing regardless of account count, with a hosted mcp

    verdictflat monthly pricing whatever your account count, plus a working hosted mcp server — held back by being an ai content product with an api rather than an api company.

    best for
    n8n and make workflows, and anyone burned by per-account pricing

    rate limit
    30 req/min upload and publish

    the pricing is flat by tier rather than per account, which for a product connecting many profiles is a fundamentally different economic shape from ayrshare's.

    there is a discrepancy worth knowing: blotato's pricing comparison table does not list api access as an included feature, which reads as though it is gated. the api documentation states plainly that api access is included on every paid plan, with only the free trial excluded. trust the docs — but be aware the pricing page will confuse your finance team.

    the hosted mcp server is documented as working with claude code, claude desktop and cursor, and there are official n8n and make nodes that blotato itself recommends over raw api calls. rate limits are published at thirty requests a minute for both media upload and publishing.

    the honest framing is that this is an ai content-generation product — ai writer, video, images — that has an api, rather than an api-first infrastructure company. credits are consumed by generation, which muddies cost prediction, and the documentation is thinner than ayrshare's.

    pros
    • +flat pricing regardless of connected account count
    • +hosted mcp server working with claude and cursor
    • +official n8n and make nodes, actively recommended
    • +documented 30 req/min limits
    cons
    • pricing table contradicts its own api docs on access
    • generation credits complicate cost modelling
    • content product first, api second — thinner docs

    create an app password and start calling. no app review, no business verification, no partner programme, no screencast. in a category where every other first-party platform gates access behind weeks of process, that is a genuine outlier.

    writes use a points budget — creates cost three points, updates two, deletes one — against five thousand points an hour and thirty-five thousand a day, which works out to roughly 1,600 creates an hour. there are official typescript and go sdks from bluesky itself, plus community python and dart libraries.

    the firehose is the thing nobody talks about enough. you can consume the entire network's activity in real time, for free. on every closed platform that capability either does not exist or costs enterprise money. for social listening agents this is unmatched.

    the trade is reach. the audience is much smaller than x, instagram or tiktok, and because the protocol does not centralise engagement metrics the way closed platforms do, analytics are thin. every agent builder should start here while waiting on other platforms' approvals.

    pros
    • +no approval process of any kind — start immediately
    • +open firehose for real-time whole-network access
    • +generous point-based limits: ~1,600 creates/hour
    • +official typescript and go sdks, self-hostable pds
    cons
    • much smaller audience than the closed networks
    • minimal built-in analytics
    • no official mcp server, though community ones exist

    eleven platforms with publishing, comment and dm read-and-reply, review management, profile analytics and webhooks. the engagement coverage is more complete than most of the cheaper aggregators, which tend to stop at publishing.

    pricing runs from free with ten posts a month through $17, $49 and $99 tiers up to a $699 enterprise plan, and api access, sdks and webhooks are included at every level. being able to build and test the real integration before paying is rare here.

    mcp is supported alongside n8n and zapier.

    it is early-stage, and that is the main caution. treat it as a higher-risk dependency than buffer or ayrshare, and check that the platform list still matches your needs before committing.

    pros
    • +api, sdks and webhooks on the free tier

    unlimited social accounts and unlimited team members at every paid tier. against a per-profile subscription the arithmetic is not close over a couple of years.

    the free lite tier only covers three networks, which makes it too limited to serve as a real evaluation — budget for the paid licence if you want to assess it properly.

    as with postiz, self-hosting means you carry the operational burden and, more importantly, every platform approval. posting directly to tiktok requires passing tiktok's audit under your own client, which is the same wall you would face building from scratch.

    pros

    for a multi-tenant product that is the decisive difference. per-profile pricing elsewhere scales linearly with your customer count and destroys margins; this does not.

    api access is included even on the free tier, which covers twenty posts a month across three accounts — enough to build against.

    x costs are handled as prepaid pass-through at x's own rates, stated openly rather than buried. fourteen-plus platforms including discord, slack, mastodon and google business, which is broader on the messaging side than most.

    the current model is pay-per-usage: buy credits, they deduct per request, no contract and no minimum spend. that is a real improvement — you can start with a few dollars and there is no approval process. duplicate requests within a rolling twenty-four hour window are not charged twice, which is genuinely useful for polling design.

    then there is the link tax. a post costs $0.015. a post containing a url costs $0.200. that is a thirteen-fold multiplier on exactly the thing most social automation does, and a thousand link posts a month is two hundred dollars in raw x fees before any aggregator subscription. every aggregator now passes this straight through. model it before you commit to anything.

    reads are cheap individually — a tenth to a half a cent — but capped at two million post reads per billing cycle, above which you are into an enterprise conversation.

    x now ships official mcp servers, and there is a detail worth catching: the action mcp covers search, user lookup, bookmarks, trends and article publishing, but it does not expose regular post creation. you can bookmark and publish articles through it; to actually tweet you still need the rest api. also worth knowing this is the third pricing regime since 2023, so budget for it changing again.

    pros

    • +official mcp servers for search, bookmarks and articles
    • +usable at genuinely small scale

    it covers single and carousel posts, media retrieval, profile management, reply moderation, mention handling, analytics, webhooks, keyword search and embeds. permissions are granular, so you request only what you use.

    access friction is meaningfully lower than the rest of meta. threads was built with more developer-friendly onboarding and it shows.

    the general call budget scales with impressions, which punishes low-reach accounts — a growth-stage account will bind on that long before it hits the posting quota. and the audience is smaller than instagram's, so it is rarely the only integration you need.

    phyllo is not a posting api and should not be compared with the aggregators above on that basis. it aggregates consented creator data — the user authenticates, you read their authenticated metrics, including private ones no scraper can reach.

    that consent model is the whole value. it is legally clean in a category where most alternatives are scraping vendors operating against platform terms, and for anything customer-facing or funded that difference matters more than price.

    coverage spans youtube, tiktok, instagram, x, facebook, linkedin, snapchat and twitch among others, with social listening, screening, video intelligence and tiktok shop products alongside.

    pricing is not published — the page offers customised plans and a quote form, with a free sandbox for evaluation. a $199 monthly figure circulates on software directories and does not appear on phyllo's own site. its closest competitor, insightiq, is a separate company in the same niche and worth evaluating alongside it.

    defaults are three hundred requests per five minutes per account and per ip, with media uploads and status deletions capped at thirty per thirty minutes, and standard rate-limit headers on every response.

    the caveat that trips up most integrations: those are hardcoded defaults, and individual instance admins can configure different limits. your code has to read the headers and adapt rather than assuming the documented numbers.

    federation is both the feature and the friction. there is no single api host, so supporting many instances means per-instance oauth apps, and an instance admin can rate-limit or defederate you. the audience is small.

    pros
    • +free with no approval process at all
    • +stable api that rarely introduces breaking changes
    • +proper rate-limit headers on every response
    • +many mature community libraries
    cons
    • per-instance limit variation must be handled in code
    • no single api host — per-instance oauth apps
    • small audience and instance admins can defederate you

    100 posts / 24h; 200 × users / hour

    there are two current apis: one where the user authenticates with instagram directly and no facebook page is involved, and one requiring the account linked to a page. both need an instagram business or creator account — personal accounts have no api access at all.

    the basic display api was shut down at the end of 2024, which permanently killed personal-account access and a whole generation of feed-embed widgets. anything you read referencing it is dead information.

    publishing is capped at a hundred api-published posts per rolling twenty-four hours per account, with carousels counting as one post against a separate fifty-carousel ceiling, and an endpoint to check your remaining budget.

    the real cost is access. standard access only covers accounts you own; serving any third-party client needs advanced access, which means meta app review plus business verification plus a screencast demonstrating each permission in use. most applications are rejected first time, each round takes one to four weeks, and a realistic first build is four to eight weeks. that is why the aggregators above can charge what they charge.

    pros
    • +free to call with high limits once approved
    • +comprehensive publishing, analytics and messaging
    • +official business sdks in five languages, plus webhooks
    • +endpoint to check your remaining publishing quota
    cons
    • app review plus business verification takes 4–8 weeks realistically
    • most applications rejected on the first attempt
    • no personal-account access since basic display was shut down

    rate limit
    100 search + 100 upload + 10,000 units/day

    correct the quota model first, because most published guidance is wrong about it. google's current documentation specifies a hundred search calls, a hundred upload calls, and ten thousand units per day for everything else. search and upload were carved out into their own daily allowances; the old arithmetic of dividing ten thousand units by the cost per search happens to give a similar answer for search and gets uploads badly wrong.

    most list operations cost a single unit, captions cost far more, and every request costs at least one unit even when it fails. quota resets at midnight pacific.

    there is no paid tier. you cannot buy quota. the only route above the default is an audit and quota extension form requiring a compliance review, which community reports put at weeks to months with many applications stalling. spreading load across multiple cloud projects violates the terms and is a common way to lose access entirely.

    a hundred uploads a day caps a multi-tenant scheduler at roughly a hundred customers posting once daily. that is a harder wall than a price, because a price you can pay.

    pros
    • +free with superb official client libraries in six languages
    • +well documented and very stable
    • +most read operations cost only one quota unit
    • +no approval needed to start building
    cons
    • 100 uploads and 100 searches per day caps real products
    • no paid tier — only an audit raises the ceiling
    • spreading across cloud projects violates the terms

    rate limit
    1,000/day trial; 100/sec standard

    there are two tiers, both free. trial allows a thousand requests a day per app; standard raises that to a hundred requests a second per user, with per-category limits published in detail.

    the trap is that pins and boards created under trial access are sandbox entities visible only to their creator. your integration will appear to work perfectly — posts succeed, ids come back, no errors — and nobody will ever see the results. it is the same class of problem as tiktok's audit gate and it catches people the same way.

    upgrading to standard needs a video recording of your app completing an action through the api, verifying your oauth implementation and data handling, submitted with a privacy policy. reviews take weeks and rejections frequently come without explanation.

    the commerce and catalogue apis are genuinely good once you are through, and write limits in trial are only three hundred a day, which makes thorough testing painful.

    pros
    • +free at both access tiers
    • +100 requests/second per user once at standard
    • +strong commerce and catalogue endpoints
    • +detailed published per-category rate limits
    cons
    • trial-mode pins are invisible to everyone but you
    • upgrade review is opaque and rejections are unexplained
    • only 300 writes/day in trial makes testing hard

    500/app, 100/member on dev tier

    the community management api covers organisation posts, comments, reactions, follower and page statistics, video analytics and posting on behalf of individual profiles. the data is genuinely valuable for b2b.

    getting in is the problem. you need a registered company with a verified linkedin page, a two-tier app review, and a screencast demonstrating each use case. there is a documented gotcha where community management access is greyed out unless you use a brand-new app with no other api products, so people with ads access have to create a throwaway app, get approved, then transfer.

    more decisively, the member social permission is closed. linkedin's own faq says it is not accepting access requests due to resource constraints. if your product needs to read an individual member's posts or social activity, linkedin is simply shut to you.

    and it breaks you on a timetable: linkedin uses dated api versioning and sunsets old versions on a rolling basis, so recurring migration work is not optional maintenance, it is a permanent line item. for a solo developer or a small team, direct access is realistically unobtainable — which is exactly why every aggregator advertises linkedin support so prominently.

    pros
    • +rich analytics on a high-value b2b audience
    • +free to call once approved
    • +recently increased development-tier rate limits
    • +postman collection provided
    cons
    • member social permission is officially closed to new developers
    • requires registered company, verified page, two-tier review and screencast
    • dated versioning sunsets old versions and breaks integrations on schedule

    TikTok Content Posting API

    verdictthe most hostile major platform to small developers — you can build, test and ship a complete integration and discover every post your users make is visible only to themselves.

    best for

    600 req/min reads; posting undocumented

    the api itself is reasonable: query creator info, direct post video by file upload or url pull, post photos, check post status. read endpoints allow six hundred requests a minute.

    then there is the audit gate, and it deserves to be stated as plainly as tiktok states it: all content posted by unaudited clients is restricted to private viewing mode. unaudited clients are additionally capped at five users posting per twenty-four hours.

    the reason this is worse than an ordinary approval process is that nothing fails. your integration works. the api returns success. the posts exist. they are just set to self-only and nobody will ever see them. developers routinely ship this to production before noticing.

    lifting it requires an audit verifying terms compliance, with a privacy policy and a demo video of the full upload and oauth flow. tiktok publishes no timeline and no criteria. separately, the research api is now restricted to academic and non-profit use with commercial users explicitly ineligible, so commercial tiktok data access through official channels is effectively gone.

    pros
    • +free, with a capable posting api once audited
    • +600 requests/minute on read endpoints
    • +supports both direct file upload and pull-from-url
    • +photo posting as well as video
    cons
    • unaudited posts are private — and nothing tells you
    • 5 users per 24 hours before audit makes real testing impossible
    • no published audit timeline or approval criteria

    ~100 queries/min per oauth client

    the free tier remains usable for non-commercial work at around a hundred queries a minute per authenticated client, and community libraries like praw still work fine against it.

    commercial use is a different world. self-service registration for new commercial oauth access is effectively closed, new tokens need manual approval reported at two to four weeks with no guarantee, and commercial use requires a contract. there is no small paid tier — you go from free and non-commercial straight to enterprise negotiation.

    machine-learning use of reddit data is prohibited without a licensing deal, and reddit has instead signed direct ai licensing agreements with major model providers. that is the strategic logic behind all of it.

    one note on the numbers you will find elsewhere: a specific enterprise price for fifty million calls circulates widely with identical wording across many sites and traces to no primary source. the arithmetic works out exactly from the per-call rate, which strongly suggests someone calculated it once and everyone copied it. we are not repeating it.

    pros
    • +free tier genuinely usable for non-commercial projects
    • +mature community libraries still work
    • +academic tier available at reduced cost
    • +high-quality discussion data if you can license it

    creative kit is a client-side share mechanism, not a server-side api. a human taps a share button and the content opens in snapchat's own camera screen for them to edit and send. there is no way to publish on a user's behalf programmatically.

    that means any tool advertising snapchat posting is either using creative kit — which requires the human tap — or doing something unsupported. it is worth checking what an aggregator actually means when it lists snapchat among its networks.

    the marketing api is a different and much better story: full programmatic advertising with campaigns, reporting, attribution, audience management and creative upload, open to all advertisers, agencies and developers for years. as paid-social apis go it is among the easiest to get production access to.

    so for advertising, snapchat is genuinely accessible. for the organic posting and agent use cases this ranking is written for, it is not gated — it simply does not exist.

    pros
    • +marketing api is open to everyone with no partner gate
    • +full programmatic advertising including creative upload

how this ranking was made

prices come from the vendor's own pricing page, fetched on the review date. where a vendor's pricing page and its developer docs disagree — and that happened more than once here — we say so and tell you which to trust.

we separate access friction from price, because in this category they are almost unrelated. an api that costs nothing but needs a registered company, a verified page, a screencast and a four-week review is more expensive than one that bills you per request.

rate limits are quoted in the platform's own units — points, quota units, requests per window — rather than converted into a single made-up figure. where a limit is undocumented we say undocumented rather than estimating.

for agent relevance we looked for concrete things: an mcp server, official sdks, webhooks, and whether writes are actually supported. one major platform ships an official mcp server that cannot post to it, which is the sort of detail that only shows up if you read the tool list.

several numbers circulating widely could not be traced to any primary source — one platform's enterprise tier in particular appears to be back-calculated from its per-call rate rather than published anywhere. those are omitted rather than repeated.

we flag scraping vendors that present themselves as apis. they are not the same product, the reliability is measured in weeks, and the terms-of-service risk sits with you rather than with them.
