Made in Ukraine Code style: black Test Status

⚠️ This is the branch for the unreleased v6 release. If you want the v5 branch version, go here.

We are currently working on Ulauncher v6, which is a huge rewrite. Until then we're only supporting the existing functionality in v5. No new features or improvements.

We are not yet ready to make releases or pre-releases for Ulauncher 6, as the API is not yet set and further major changes may come.

Ulauncher is a fast application launcher for Linux. It's written in Python using GTK+, and features: App Search (fuzzy matching), Calculator, Extensions, Shortcuts, File browser mode and Custom Color Themes

Run Ulauncher on startup

If your distribution uses Systemd and the packages includes ulauncher.service, then you can run ulauncher on startup by running:

systemctl --user enable --now ulauncher

If not, then you can open Ulauncher and enable "Launch at Login" in the preferences.


Please read our Troubleshooting discussion category if you run into issues, and also check our other discussions and issues if you still need help after this.
