Authlete

Authlete is an API-first OAuth 2.0 and OpenID Connect backend service that provides a headless authorization-server engine. It handles the OAuth/OIDC protocol logic and token management so organizations can stand up standards-compliant authorization servers and verifiable-credential issuers without building the protocol layer themselves. Authlete separates the Management APIs (configure services and clients) from the Runtime APIs (power authorization, token, introspection, CIBA, device-flow, federation, and OID4VCI endpoints), and offers managed shared cloud, dedicated cloud, and self-managed deployment across US, Japan, Europe, and Brazil regional clusters. It supports advanced profiles including FAPI / FAPI 2.0, CIBA, PAR, Grant Management, OpenID Federation, Native SSO, and OpenID for Verifiable Credential Issuance, plus regional open-banking standards (Brazil Open Banking, Australia CDR). Backed by 500 Global.

Authlete publishes 1 API on the APIs.io network. Tagged areas include Company, OAuth 2.0, OpenID Connect, Authentication, and Authorization.

Authlete’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 28 more developer resources.
