I keep overwriting config files and scripts and realizing it ten minutes later, and Git only remembers what you commit. So I built Rewind: point it at a folder, it watches filesystem events, hashes and snapshots every save into SQLite, and you can scrub back through a timeline and restore any version. Tech stack (split for different platforms): Windows: Tauri v2 desktop app. Engine is Rust, using blake3 for content-addressed deduplication, notify for native file watching, and rusqlite for storage. The whole UI is a single HTML file with React and Tailwind loaded via CDN, so no node_modules bloat. Linux/Ubuntu: A lightweight Python CLI available on PyPI, so you can pip install rwnd (the command is still rewind). Uses watchdog + sqlite3 + rich. Rust bits I enjoyed: Added a 350ms debounce to the file watcher, because editors fire multiple save events (temp file, rename, actual write) for a single Ctrl+S, and without debouncing the timeline gets flooded. Also deduplicated storage via blake3 hashing, so repeated saves of identical content cost nothing. Try it: Windows: Grab the .exe installer or standalone CLI from Releases (unsigned, SmartScreen will warn). Linux: pip install rwnd then rewind watch . Honest limitations: Not a backup (lives on local disk). Only sees changes while watcher runs. Skips files >25MB. Doesn't track deletes/renames yet. GUI is Windows-only for now. Testers on other Linux distros or macOS would be especially helpful. Repo: https://github.com/hcentral07/rewind   submitted by   /u/Educational_Pace_525 [link]   [comments]
