9 tools we tested head to head against Helicone, ranked — and what each one actually does differently.

last reviewed 17 aug 2026 · from our best 10 llm routers and ai gateways ·list curated by Onur Ozcanxin

first — what you'd be leaving

Helicone ranks #3 of 10 in our llm gateways testing. the gateway and the observability layer in one apache 2.0 codebase.

84/100

the cleanest open-source licence in the category paired with a real 0% token markup, let down by overage rates you cannot read off the page.

why people look for an alternative
  • overage rates live in a calculator, not on the pricing page
  • data retention is one month on pro, three on team
  • $79 entry price is the highest of the pass-through gateways

stay with Helicone if apache 2.0 throughout with no enterprise carve-out found is the thing you care about most — nothing below beats it on that.
