FeatBit is an open-source feature flag and A/B testing platform for controlled releases and experiments. It offers flag management, user targeting and reusable segments, scheduled changes, approval workflows, audit logs, access control and SSO. SDKs cover .NET, JavaScript, React, Java, Python and Go, among others, including OpenFeature providers. FeatBit is available as a cloud service or can be self-hosted with Docker Compose, Kubernetes, or on AWS and Azure.
Most of the code is MIT-licensed, while some features require a licence key (open core). The company page lists FeatBit Inc., a Colorado corporation, and a Hong Kong company as its legal entities; which one contracts depends on the customer's location. The website does not state where the managed cloud is hosted. Self-hosting lets an organisation keep flag data on its own infrastructure, including within the EU, and a relay proxy can run in a private environment. European organisations should confirm the contracting entity and the hosting region of the cloud service before adopting it.
