Reviewer scorecard
“10x faster package installs, native TypeScript, and built-in test runner. It's replacing Node.js in my new projects.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Speed is real and measurable. Node.js compatibility is good enough for most projects. The future of JS runtimes.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Bun is forcing Node.js to improve. Competition in runtimes benefits everyone. Speed + DX is the winning combination.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
