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
“Non-negotiable for any serious component library. Visual testing, docs, and interaction testing in one place.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“The best way to browse and understand a design system. Addons for accessibility and responsive testing are invaluable.”
“Setup can be painful and builds are slow, but the alternative — no component isolation — is worse.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
