Runs where you already are
One command deploys it to Cloudflare Workers, where it costs nothing when idle. Or run the same server as a container on Render, Fly.io, Railway, a VPS or Kubernetes.
Flaghoist
Open-source feature flags you host yourself. Run it free on Cloudflare Workers or as one container anywhere, read flags from any language through OpenFeature, and give your team its own sign-ins and roles.
Why Flaghoist
Section titled “Why Flaghoist”OpenFeature-native
The read API is the OpenFeature Remote Evaluation Protocol (OFREP), so Go, Java, Python, .NET, Ruby, Rust and JavaScript read flags through their standard providers.
Your database
Flags live in storage you already run: Cloudflare KV, Redis, Postgres or SQLite. A storage adapter is four methods if you need another.
Built for a team
Accounts with four roles, invites, single sign-on with your identity provider, two-factor codes, personal access tokens, and an audit log of every change.
The shape of it
Section titled “The shape of it”Flaghoist has two independent halves:
- The flag service, deployed once for your team on your own infrastructure. It keeps flags in
your storage and serves the OFREP read API, an admin API, and a dashboard at
/admin. - Your apps, which install an OpenFeature provider and read flags. They never import Flaghoist, so moving to another backend later is a one-line change.
