Our verdict

LangSmith describes itself as view in LangSmith. No free tier is advertised, though pricing is at least public. Developer documentation and a public changelog are both maintained, which is a good sign for anything you intend to build on. We have not verified the prices by hand, so we do not quote them here. Everything above was checked on 2026-08-26.

Pricing

  • Free tierNo
  • Public price listYes

We do not republish prices we have not checked by hand, because automated price extraction proved unreliable enough to mislead. The vendor’s own page has the current figures. Why we do this
