Yes, AGPL. And yes, it’s open core. For personal use you can self-host the server and SDKs with no usage limits, and that covers flags, targeting, gradual rollouts and variants. The paid tiers add things that mostly matter to larger teams: SSO, RBAC, change requests, and Edge for high-volume frontend traffic. For a personal setup, the open source version should be all you need.
