Launched the Keycloak + MongoDB Edition of my .NET 8 Minimal API Starter Kit

A few days ago I launched FenixKit — a .NET 8 Minimal API starter with MongoDB, a hook-based repository, dual pagination, and ErrorOr result pattern. It just didn't have auth.

Today I'm launching the MongoDB + Keycloak Edition.

It includes everything from the original kit plus a fully pre-configured Keycloak layer: JWT Bearer via OIDC, role-based policies (Authenticated and AdminOnly), OAuth2 PKCE in Swagger with a working Authorize button, and a pre-built realm that imports automatically at startup — two test users ready, zero manual Keycloak configuration.

401 and 403 return structured RFC 7807 ProblemDetails. docker compose up and the API, MongoDB, and Keycloak are all running.

Launch price €45 — code FIRSTXPEOPLE for €15 off at fenixkit.dev for early adopters
