FeatBit

FeatBit is an open-source, MIT-licensed feature flag and toggle management platform founded in 2021 with its primary entity headquartered in Paris, France and affiliates in the US and Hong Kong. Built primarily in .NET, it can be self-hosted on-premises or on Azure, AWS or GCP via Helm charts, or used as a managed cloud service. The platform handles flag evaluation, percentage rollouts, segmentation, audit logs and integrations for traditional release pipelines as well as AI-native workflows. The free open-source edition is fully featured; the cloud and enterprise tiers add SLA support and managed hosting.
