What is OAuth Flow Visualizer?

An OAuth flow visualizer helps developers understand the different OAuth 2.0 authorization grant types by showing step-by-step diagrams of the request/response flow between the client, authorization server, and resource server.

FAQ

Authorization Code with PKCE is recommended for most applications. Use Client Credentials for server-to-server communication.
