Pricing

Free during the developer beta.

The public decision API is open today and needs no key. Authoring is in invite-only beta.

Public rulesets are free; private rulesets are a Pro-tier feature — like GitHub for rulesets.

Our commitments

Decisions are free during the developer beta. Production pricing will be announced 30 days before any change, with grandfathering for existing usage. The free tier will always exist.

  • Free during the beta. Until production pricing is announced, decisions and authoring are free.
  • 30 days notice before any pricing change. No surprise charges.
  • Grandfathering. Existing tenants keep their previous rate or quota for at least the notice period.
  • No retroactive billing. Free usage stays free.
  • Free tier won't be removed. The numbers may be calibrated; the tier itself is permanent.

Decisions don't call a language model in the request path, so the marginal cost is small. Authoring uses your own Anthropic key.
