FlagTGL documentation
FlagTGL is a feature-management SaaS for controlling releases after code is deployed. Use FlagTGL Cloud to manage flags, environments, targeting, rollout state, access, and evaluation traffic without operating a control plane.
Self-hosting is also available when policy or architecture requires your team to run the platform in its own infrastructure. It is a deployment option—not a prerequisite for using FlagTGL.
What you can do
- Release progressively across development, staging, UAT, and production without redeploying.
- Target any context kind such as a user, tenant, organization, device, or your own domain entity.
- Observe flag usage with evaluation totals, context kinds, API traffic, latency, and lifecycle status.
- Migrate from LaunchDarkly while preserving variations, individual targets, rules, prerequisites, segments, environment settings, and existing SDK call patterns.
- Govern production changes with roles, personal access tokens, audit history, and critical environments.
- Stream updates in real time to server, browser, mobile, and relay clients.
