What is FlagPulse? ​

FlagPulse is a self-hostable feature flag management platform aimed at solo developers and small teams. Instead of paying for a hosted flag service or hand-rolling if statements around environment variables, you run FlagPulse alongside your app and get:

  • A dashboard for creating projects, environments, and flags
  • A small REST API that your services and CI/CD can drive
  • A Client SDK API (x-sdk-key protected) that your applications call to evaluate flags
  • Realtime updates over Server-Sent Events (SSE), so a flag toggle shows up in connected clients immediately
  • An audit log of every change, with old/new values

Why FlagPulse ​

  • Fast to stand up. One docker-compose up brings up Postgres, Redis, the API, and the dashboard behind Nginx.
  • No vendor lock-in. Your flag data lives in your own Postgres instance.
  • Per-environment isolation. Each environment (e.g. production, staging) has its own SDK key and its own set of allowed origins, so a leaked staging key can't be used against production.
  • Cache-first evaluation. Flag reads are served from Redis with a 5-minute TTL and are invalidated immediately on writes, so SDK reads stay fast without going stale.

Who it's for ​

FlagPulse is intentionally scoped for a single team's use case, not a multi-tenant enterprise rollout — there's no org/workspace layer, and authorization is currently project-ownership based rather than role-based. If that fits how you ship, it should feel very quick to adopt.
