Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“EAS Build, OTA updates, and the managed workflow eliminate the worst parts of mobile development. Indispensable.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“Expo has matured from toy to production platform. The config plugins and custom dev clients removed the old limitations.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“Expo is making React Native the default for mobile. Universal apps (web + mobile) from one codebase is the future.”
