Featbit
A self-hosted feature flag platform for gradual rollouts, impact monitoring and instant rollback, with a web portal and official SDKs.
Featbit at a glance
What is Featbit?
FeatBit gives a team a web portal for creating flags and SDKs that evaluate them inside the application by key. A typical use is to switch a new code path on for a small group of users, widen the audience step by step while watching technical and business effects, and turn it off at once if something breaks. The quick start brings up the whole stack with Docker Compose and PostgreSQL on a single machine. Besides Compose, the README describes deployments to AWS and Azure Container Apps through Terraform and to Kubernetes with manifests.
Good fit if
- You want gradual feature rollouts on your own infrastructure, on-premises or in your cloud account.
- People who do not deploy code should be able to toggle flags from a portal.
- Your stack includes .NET, which the README uses for its SDK example.
Look elsewhere if
- You also need remote config and experiments from a project under a BSD license: Flagsmith.
- You need every feature without a license key: the README says some FeatBit features require one.
Before you adopt it
The README calls FeatBit open core: most code is MIT, but certain features need a valid license key, and the data check found no separately licensed folders. No CLA is required. The featbit organization maintains it, with six people committing in the last 90 days. Change the default login from the quick start before exposing an instance. FeatBit Cloud is the hosted alternative.
