FAQ

Can I use my existing LaunchDarkly SDKs with FlagTGL? Yes, for the documented compatibility surface. Configure the SDK's service endpoints for FlagTGL and replace its environment credential with a FlagTGL SDK key. Validate your targeting behavior in staging before moving production traffic.

What database does FlagTGL use? FlagTGL uses PostgreSQL. The schema is managed automatically through built-in migrations that run on startup.

Is FlagTGL SaaS or self-hosted? FlagTGL Cloud is the recommended managed SaaS. A self-hosted deployment is also available for organizations that need to operate the control plane in their own infrastructure. Compare deployment options.

How does percentage rollout hashing work? Users are assigned to a variation using a consistent hash of their user key and the flag key. This ensures the same user always sees the same variation, even across server restarts or SDK reconnections.

Can I run multiple environments in a single FlagTGL instance? Yes. A single FlagTGL deployment supports multiple organizations, projects, and environments. Each environment has its own SDK key and independent flag configurations.
