Reviewer scorecard
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
