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
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
