Owlry

A lightweight, owl-themed application launcher for Wayland, built with GTK4 and Layer Shell.

Features

• Provider-based architecture - Search applications, PATH commands, and systemd user services
• Fuzzy search - Fast, typo-tolerant matching across all providers
• Filter tabs & prefixes - Scope searches with UI tabs or :app, :cmd, :uuctl prefixes
• Systemd integration - Manage user services with submenu actions (start/stop/restart/status/journal)
• GTK4 theming - Respects system theme by default, with optional custom themes
• CSS variables - Full customization via config or custom stylesheets
• Wayland native - Uses Layer Shell for proper overlay behavior

Theming

GTK Theme (Default)

Owl Theme

Enable the built-in owl-inspired dark theme:

[appearance]
theme = "owl"

Custom Theme

Create a custom theme file at ~/.config/owlry/themes/mytheme.css:

:root {
    --owlry-bg: #1e1e2e;
    --owlry-bg-secondary: #313244;
    --owlry-border: #45475a;
    --owlry-text: #cdd6f4;
    --owlry-text-secondary: #a6adc8;
    --owlry-accent: #f38ba8;
    --owlry-accent-bright: #f5c2e7;
}

Then reference it in config:
