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
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
