ComfyLauncher gives portable ComfyUI what it's missing. The standalone build launches in its own window; the portable one opens in your default browser — heavy and full of tabs. ComfyLauncher brings its own lightweight window and one-click launch.
The idea grew out of real work: you keep separate builds for different tasks — WAN, Qwen, image generation, testing new nodes — to avoid environment conflicts. ComfyLauncher gathers them in one place and launches any of them from a start menu.
The result feels closer to a regular desktop app: one window instead of a browser full of tabs, a fast start for the build you need, and clear control over the server — restart, stop, folder access, status. Less busywork to launch and switch — more time for the actual generation.
