Migrate from LaunchDarkly

FlagTGL is designed as a drop-in replacement for LaunchDarkly. The relay proxy exposes LaunchDarkly-compatible endpoints, so you can migrate by updating your SDK configuration to point to your FlagTGL instance.

Migration Steps​

  1. Set up FlagTGL -- Deploy the FlagTGL backend and create your project, environments, and flags to mirror your LaunchDarkly setup.
  2. Update SDK base URLs -- Change BaseUri, StreamUri, and EventsUri in your LaunchDarkly SDK configuration to point to your FlagTGL relay proxy.
  3. Replace SDK keys -- Swap your LaunchDarkly SDK keys for FlagTGL environment SDK keys.
  4. Verify -- Test flag evaluations in a staging environment before switching production traffic.

No code changes are required beyond updating the configuration. The FlagTGL SDKs also provide a LaunchDarkly-compatible interface for teams that want to switch to the native client.
