Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“The best local development experience for edge functions. Miniflare emulates the entire Cloudflare platform locally.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“Local emulation of D1, R2, KV, and Durable Objects means you develop at full speed without deploys.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“Local-first development tools for edge platforms will become the standard. Wrangler leads this pattern.”
