Refactyl

What it does

Refactyl is an AI-powered tool that automatically transforms messy, outdated codebases into clean, modern, production-ready projects. 🔁 Migrate frameworks (Express → Fastify, JS → TypeScript) 🧱 Improve structure for scalability & maintainability 🧹 Reduce technical debt without manual refactoring ⚡ Save hours of repetitive engineering work Built for developers dealing with legacy code who want to ship faster with confidence.

Refactyl runs code migrations that compile: JS→TS, Vue 2→3, Next.js Pages→App Router, Express→Fastify. The real compiler checks every file before you download it.

Refactyl automates four compiler-verified migrations: JavaScript to TypeScript, Vue 2 to 3, Next.js Pages to App Router, Express to Fastify. It checks every output file against the real compiler before you ever see it. The benchmark numbers show single-pass tsc results. That's the raw first run, before repair. In the product, the Verify & Repair loop re-runs the compiler after every pass and keeps fixing until the build is clean, or the file is flagged. “First handoff” means the diff you receive already builds. The same engine that migrates whole repos, scoped to a single file.

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
