The models' case: The strongest self-hostable flag platform for regulated environments — Enterprise edition runs fully on-prem/air-gapped with the Unleash Edge/Proxy keeping evaluation and. The models' main caveat: The governance that earns the rank (change requests, SSO/SCIM, RBAC granularity) lives in the paid Enterprise tier — the free OSS core lacks approval. The strongest alternative is Flagsmith — Fully open-source and genuinely easy to self-host (Docker/K8s/on-prem), with RBAC, audit logs, environment segregation, and a clean API.
