DLauncher

DLauncher is a fast, minimal, and highly customizable Qt-based application launcher for Linux. It lets you search and launch your installed apps with style and speed.

---

Features

• Super fast fuzzy search for all your desktop apps
• Fully themable via ~/.config/dlauncher/theme (colors, fonts, window size/position, padding, border radius, and more)
• Customizable window geometry (width, height, position) and UI padding
• Font and font size selection for a personalized look
• Deduplication and prioritization of user-installed apps over system apps
• Robust .desktop file parsing and normalization
• Launches any app with all its arguments and flags (handles complex Exec fields)
• Modern, minimal, distraction-free UI
• Cross-platform build with CMake (Linux, BSD, and more)
• Lightweight, fast startup and low memory usage
• Simple C++17/Qt codebase, easy to hack and extend
• No telemetry, no ads, no nonsense EVER

Configuration & Theming

DLauncher is fully customizable via a simple config file:

~/.config/dlauncher/theme

# Example theme
background=#222222
border=#444444
text=#ffffff
highlight=#00bcd4
input_bg=#222222
input_border=#444444
font=FiraCode
font_size=18
border_radius=12
padding=14
window_width=600
window_height=350
window_pos_x=100
window_pos_y=100
selection=#00bcd4cc
row_bg=#33333322
row_hover=#00bcd455

If the file is missing or empty, DLauncher uses beautiful sane defaults.
