Unkey

Unkey is an open-source developer platform for modern APIs, providing globally distributed API key management, authentication, and rate limiting. The platform lets API providers issue, verify, update, reroll, and revoke keys with metadata, expiration, usage credits, permissions, and roles, plus standalone rate limiting, identities, RBAC, and key-verification analytics. Unkey exposes an RPC-style REST API (all POST) with a stable v2 at api.unkey.com and a legacy v1 at api.unkey.dev, authenticated with Bearer root keys.

Unkey publishes 8 APIs on the APIs.io network, including analytics API, apis API, deploy API, and 5 more. Tagged areas include API Keys, Rate Limiting, Authentication, Access Control, and Identity.

Unkey’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
