Local OIDC testing in the browser: discovery, JWKS, auth code, token exchange, ID token, UserInfo and refresh. PowerOIDC is a local OpenID Connect (OIDC) testing tool that runs entirely in your browser. Enter your provider's details and it performs the full authorization-code flow — discovery, JWKS, authorization URL, token exchange, ID-token decoding and claim validation (iss, aud, nonce, exp, kid vs JWKS), UserInfo, and refresh — plus an optional refresh-token reuse check. Results are shown per step and can be exported as JSON. It supports both manual redirect paste and automatic capture. Nothing leaves your machine except the requests to the OIDC provider you configure — ideal for locked-down or offline environments where web-based OIDC debuggers can't be used.
