Mouzi started the way most utilities do: with an annoyed developer and a Downloads folder holding four hundred files. I wanted a small tool that would sort new downloads by my own rules, run from the system tray and never phone home. Nothing on the market fit all three, so I built it.

I'm Krystian Welcel, and I develop Mouzi after hours as an independent project. It is written in Rust with Tauri, ships for Windows and Linux, and is MIT licensed. There is no company behind it and no plan to bolt on a subscription. The app is free, the source is public and the roadmap is driven by GitHub issues.

Principles

• Local-only. A file organizer sees everything you download. That data stays on your machine, full stop.
• Quiet. Mouzi should be forgotten a day after installation. No popups, no upsells, no badges begging for attention.
• Reversible. Successful moves are recorded in History, where Mouzi can move a file back if it still exists at the recorded destination.
• Inspectable. The source and release workflows are public, so you can see how the application is built.

The stack, briefly

Rust handles the file watching, rule engine and SQLite history. Tauri provides the UI shell, which keeps the installer small, a few megabytes rather than a bundled browser. The interface is translated into 10 languages by contributors.

Get in touch

The best channel is GitHub: issues for bugs and features, private advisories for security. I'm also on X and r/Mouzi, or by email at haser88@gmail.com.
