Become a sponsor to Krystian

Hi, I’m Krystian. I build small, practical tools for problems that annoy me - usually with a focus on privacy, speed, and keeping things local.

My main project right now is Mouzi, an open-source file organizer for Windows and Linux. It watches your Downloads folder, sorts new files using rules you control, and stays quietly out of the way.

Everything runs on your computer. There are no accounts, cloud uploads, subscriptions, or telemetry.

I also maintain projects such as Log Voyager and EnvTunnel, along with a handful of smaller browser and desktop tools.

I work on these projects after hours. Sponsorship helps cover things like code signing, testing, documentation, and support for new platforms. More importantly, it gives me more time to fix bugs and keep building.

Nothing is locked behind sponsorship. If something I made has been useful to you and you’d like to support its development, you can do that here.

Thank you - it genuinely helps.
