Clerk

$25 a month at fifty thousand users, with one sso connection included

$25/mo (pro)#product-teams-who-want-t#will-not-hit-enterprise-

the cheapest credible option at mid-scale by a wide margin, priced per application rather than per account.

clerk's pro plan is $25 a month and includes fifty thousand monthly retained users. overage starts at the fifty-thousand-and-first user at two cents each, so the anchor for this category — total cost at 50,000 users — is $25 flat. auth0 charges $3,500 for the same workload. that is not a rounding difference, and it is the single most useful fact on this page.

note the unit. clerk bills monthly retained users rather than monthly active users, which is a narrower definition, and the free hobby tier is capped at the same fifty thousand with a hard ceiling rather than an overage path. the practical effect is that hobby covers a surprisingly large product until the day it stops entirely.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

the cheapest credible option at mid-scale by a wide margin, priced per application rather than per account.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
