stubIdP

stubIdP is a lightweight mock OpenID Connect (OIDC) server designed for developers who need to test authentication flows quickly and reliably.

It allows you to simulate an identity provider without the complexity of deploying and configuring a real authentication system. With zero setup required, stubIdP enables rapid testing of OAuth2 and OIDC integrations in local or CI environments.

Features

• Zero configuration: start instantly with no setup required
• OIDC & OAuth2 testing: validate authentication and authorization flows
• Developer-focused: built specifically for local development and integration testing
• Fast setup: run a mock identity provider in seconds

Use cases

• Testing login flows during development
• Validating OAuth2 / OIDC integrations
• Running automated tests without external identity providers
• Prototyping authentication features

stubIdP helps developers avoid the overhead of managing a real identity provider while still working with realistic authentication scenarios.
