In their own words
Flipt
Flipt is a feature flag platform for managing feature releases, with changes made in its interface becoming Git commits teams can review. It supports targeting rules, user segments, percentage rollouts, and approval workflows; the site says streamed flag changes apply in milliseconds. Flipt v2 is described as a self-hosted single binary with no dependencies. Interfaces include REST and gRPC APIs, client-side SDKs, and OpenFeature, with native SDKs for Go, Python, JavaScript, C#, Swift, Kotlin, and Dart. Git integrations include GitHub, GitLab, BitBucket, and Azure DevOps. The free Open Source plan includes unlimited flags, Git workflows, UI synchronization, real-time updates, APIs, and community support. Flipt Pro costs $200/mo and adds Git-provider integration, pull requests from the UI, GPG-signed commits, secrets management, and a dedicated Slack channel. A 14-day Pro trial is available without a credit card. Flipt announced its hosted Flipt Cloud service would shut down on August 29, 2025.
