Reviewer scorecard
“Best auth DX available. Pre-built components look great, the middleware is solid, and the dashboard is useful.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Auth is a solved problem you shouldn't be building yourself. Clerk makes it fast and reliable.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Authentication as a service is becoming the default. Clerk's component-first approach makes it seamless.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
