ArchSync
See what your change breaks in other repos before you push
ArchSync reads all your repos (apps, APIs, services, databases) and builds one live map of how they connect. Catch cross-repo breaking changes before you push, onboard faster and give Claude Code or Cursor real context over MCP. Code never leaves your machine.
Hey Product Hunt 👋 I'm Vivek, and I built ArchSync.
The Problem
Every system I've worked on is split across repos: a backend, a web app, an admin panel, a mobile app, a couple of services. Nobody has the whole picture in their head. So a "small" API change breaks a mobile screen nobody remembered, new joiners spend their first weeks asking "where does this actually happen?", and AI coding agents confidently edit one repo without knowing the other three exist.
What does ArchSync does?
archsync scan reads your repos locally — routes, screens, controllers, services, models, middleware and the HTTP calls between them. JS/TS, Python, Go, Java, Kotlin, Dart, Swift and more. No annotations.
It matches every frontend call to the backend route that answers it, across repos. Change a route and scan again: it lists every call that no longer has anything answering it, before you push.
The canvas shows the whole system as one map, down to the exact line each arrow comes from.
Over MCP, Claude Code, Cursor and Windsurf can ask "which repos does this task touch?" and get real entities with file and line, and when the map has a gap, it says so instead of guessing.
Privacy
Your source code never leaves your machine. Scanning is 100% local. If you share the map with your team, it goes to your own Supabase project (metadata only: names, routes, file paths, line numbers), not to us. Semantic search uses your own Voyage/OpenAI key.
I'd love your honest feedback — especially from teams with lots of services or a mobile app + backend + admin + other micro services. What's missing for you?
