Warrant Dev Plans Pricing
Warrant had two consumption models. The core authorization engine is open source (Apache-2.0) and free to self-host with no vendor fee - your only cost is the infrastructure and datastore (MySQL, Postgres, or SQLite) you run it on. The hosted Warrant Cloud offered a free developer tier for getting started and a usage-based paid tier metered on authorization activity (objects, warrants, and access checks), with a custom/enterprise tier for high-volume deployments. RETIRED - Warrant was acquired by WorkOS (2024-04-23) and the hosted service was sunset 2025-11-15; the specific historical free-tier numeric limits and per-unit rates were not reconciled here. Current fine-grained authorization pricing is set by WorkOS FGA.
