Flipt
Flags defined in Git, evaluated by one Go binary.
93
sovereigntyFlipt takes a GitOps approach: flag definitions live in your repository as files, get reviewed in pull requests like any other change, and are evaluated by a single Go binary that can run entirely offline with no external dependency. For a platform team that already runs everything through Git, this makes flags an ordinary part of the deployment pipeline rather than a separate control plane somebody has to remember to check. GPL-3.0 with about 4.9k stars. The trade is deliberate: no polished dashboard for product managers, because the source of truth is a file.

What it does well
- +Flag definitions live in Git — reviewed, versioned and audited like code
- +Single Go binary, runs air-gapped with no external calls
- +Fits a GitOps workflow with no extra machinery
- +GPL-3.0 with no enterprise carve-out
Where it falls short
- −Smallest project here — a real bus-factor consideration
- −No dashboard a non-engineer will happily use
- −Git-based workflow means non-technical staff cannot flip a flag
- −No experimentation or statistics
