Unleash is an open-source feature flag system with gradual rollouts, A/B testing, and SDKs for every language. Self-hostable alternative to LaunchDarkly.
Reviewer scorecard
“Perfect for prototyping. I described a dashboard and had a working app in 3 minutes. Not production-ready, but unbeatable for speed-to-demo.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“Impressive demo, but the generated code is messy and you'll rewrite most of it. If you can't code, you can't fix what it breaks. Know what you're getting into.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“As a creator who needs quick landing pages and MVPs, this is a game-changer. I built a waitlist page with email capture in under 5 minutes.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
