Reviewer scorecard
“10x faster package installs, native TypeScript, and built-in test runner. It's replacing Node.js in my new projects.”
“The best local development experience for edge functions. Miniflare emulates the entire Cloudflare platform locally.”
“Speed is real and measurable. Node.js compatibility is good enough for most projects. The future of JS runtimes.”
“Local emulation of D1, R2, KV, and Durable Objects means you develop at full speed without deploys.”
“Bun is forcing Node.js to improve. Competition in runtimes benefits everyone. Speed + DX is the winning combination.”
“Local-first development tools for edge platforms will become the standard. Wrangler leads this pattern.”
