In their own words
GO Feature Flag
GO Feature Flag is an open-source feature-flag management system built on OpenFeature for infrastructure you control. Its relay proxy runs locally with Docker and a flag configuration file. Teams can target users and segments, use percentage or progressive rollouts, schedule changes, and run A/B tests. Client and server SDKs are listed for 16 languages and frameworks, including JavaScript, TypeScript, React, Swift, Kotlin, Go, Java, Python,.NET, Ruby, Rust, and others. Retrievers load configuration from HTTP(S), local files, Kubernetes ConfigMaps, cloud storage, Git providers, MongoDB, Redis, and PostgreSQL. Exporters send evaluation data to Kafka, AWS S3, BigQuery, OpenTelemetry, webhooks, or logs. Notifications can reach Slack, Discord, Microsoft Teams, webhooks, or logs. The MIT-licensed Opensource plan costs nothing, billed forever, with all features, unlimited flags, and community support.
