As answered by people managing StackBlitz and ShadowGit.
ShadowGit's answer:
ShadowGit is the only tool where AI assistants can directly search your code history to debug faster while using 50% fewer tokens. Auto-captures every change without touching your main git repo. Built specifically for AI-assisted development.
ShadowGit's answer:
Electron is the primary technology being used.
ShadowGit's answer:
ShadowGit is the only tool built specifically for developers using AI. Unlike generic backup tools, your AI can actually search the history to debug faster and use 50% fewer tokens. Separate shadow repo means your main git stays clean. 100% local.
ShadowGit's answer:
AI-Accelerated solo developers that use AI coding assistants daily (Claude, Cursor, Copilot), experienced enough to feel the pain (2-10 years of coding) and that want to move fast, ship often and experiment constantly.
ShadowGit's answer:
I built ShadowGit after losing 3 hours of work to a bad AI refactor. Started as a personal backup tool, but when I added MCP integration so AI could search the history, debugging time dropped 80%. Had to share it.

StackBlitz claims to allow you to code the future in your browser. And after trying it, I’m confident you’ll agree that this web application is extremely useful for coders.
