Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“As a creator, I can now prototype landing pages in minutes instead of hours. The Figma-to-code flow is a game changer for my workflow.”
