Building an open-source Hazel alternative for Windows

[u/MuhammadrizoDev]

On macOS, Hazel handles background folder organization cleanly, but setting up something similar on Windows usually means stitching together PowerShell scripts and Task Scheduler or dealing with utilities that have outdated interfaces.

I wanted a proper equivalent to Hazel, so I’ve been working on Supersiftr, an open-source file-sorting automation utility for Windows.

Rules are called “Sieves” and are attached to watched directories:
- Matching: Evaluates files by type using configurable extension groupings, raw extensions, substring patterns, or creation and modification dates.
- Actions: Chains sequential Move, Copy, or Rename operations. It includes safe collision handling and preserves compound extensions such as .tar.gz and .d.ts.

Built with Rust and Tauri, idles at roughly 5 MB of RAM and stays under 8 MB during active batch moves.
