GO Feature Flag is an open-source, OpenFeature-native feature flag management system that runs self-hosted on your own infrastructure with no database required. It supports file-based (YAML) flag configuration, gradual rollouts, targeting rules, usage data collection, and SDKs/providers for 16 languages and frameworks.

Use cases

  • self-host a feature flag service without a database
  • roll out a new feature to 10% of users and increase gradually
  • instantly roll back a feature with a kill switch
  • target flags to specific user segments or environments
  • evaluate feature flags in Go, Java, .NET, Android, iOS, React, or Angular apps
  • collect usage analytics on which flags are being evaluated
  • manage flags in YAML files integrated with my existing tooling

When to choose

  • you want a 100% open-source, vendor-lock-free feature flag solution
  • you prefer self-hosting on infrastructure you already run with minimal setup
  • you want OpenFeature standardization and multi-language SDK support
  • you need gradual rollouts, targeting, and experimentation without per-seat pricing

When to avoid

  • you want a fully managed SaaS with a polished enterprise UI and support
  • your team needs advanced analytics dashboards or A/B testing statistics out of the box
  • you are not willing to run even a lightweight Docker container or relay-proxy
