About Flagsmith
Feature flag platform meets developers where they already work — Backstage, GitHub, Sentry — while adding governance for larger teams.
Flagsmith is a feature-flag and remote-config platform shipping monthly-ish improvements that fall into two clear arcs: bringing flag visibility into developer portals and CI surfaces (Backstage plugin, GitHub code references, Sentry tracking) and adding governance for larger teams (change requests for segments, granular permission inspection, multi-tenant segmentation).
