Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
