About Flagr
Flagr (OpenFlagr) is an open-source Go service for feature flagging, A/B testing, and dynamic configuration, exposing an evaluation API plus a management UI. Teams self-host it to gate features, run experiments, and segment users by constraints and distributions. It is aimed at engineering teams that want flag infrastructure they fully control rather than a hosted SaaS.
