Feature Flags / Remote Config
GO Feature Flag is free and open source while Convert runs on paid subscription pricing. Convert: A/B testing and personalization platform with no-cookie tracking and privacy-first architecture. GO Feature Flag: Simple, complete and lightweight self-hosted feature flag solution, 100% open source. OpenFeature-native with 15+ language SDKs via relay proxy. Convert fits gradual rollouts to reduce risk. GO Feature Flag fits engineering teams running flags in-house across many languages. On our rubric Convert scores 3/5 for developer experience and 4/5 for transparency, while GO Feature Flag scores 5/5 and 5/5. The honest trade-off: Convert's main drawback — Solo developer shipping to production; GO Feature Flag's — Config and ops are your responsibility. For GO Feature Flag: Self-hosted, 100% open source with generous features. Convert is explicitly not the right pick for solo projects. GO Feature Flag is not aimed at non-engineers wanting polished SaaS flag management. Another Convert advantage: Kill switches for features. Another Convert friction point: Products with no users yet.
Quick take
Convert is for gradual rollouts to reduce risk; GO Feature Flag is for engineering teams running flags in-house across many languages; decide on pricing model.
