Common questions
Is Flaggr a drop-in LaunchDarkly replacement?
For core flagging — targeting, rollouts, environments, SDK eval — yes. Flaggr is OpenFeature-compatible, so the SDK surface is the OpenFeature standard rather than a proprietary one. LaunchDarkly-specific features like its approval-workflow marketplace have no direct equivalent.
Why choose Flaggr over LaunchDarkly?
Cost, self-hosting, and protocol coverage. Flaggr is MIT-licensed with a Go data plane serving REST, gRPC-Web, Connect-RPC, and OFREP — you can run it in your own VPC with your own observability stack.
Can I migrate flags from LaunchDarkly to Flaggr?
Yes — export flags via the LaunchDarkly API and recreate them with Flaggr's bulk import endpoints. Flaggr's import/export API is documented and accepts standard flag definitions.
