About Vermouth

Vermouth is an open-source game launcher for Linux written in C++ with Qt and designed first for the KDE Plasma desktop. It gathers games from several places into one library: Windows games run through Proton or Wine (optionally via umu-launcher), the local Steam library can be imported, a GOG login lets you download and install GOG games, and retro games come from RetroArch ROMs or a RomM server. It also handles native Linux binaries and AppImages, fetches artwork from SteamGridDB and offers a gamepad-friendly Big Picture mode. Its main selling point is size: the project says it takes about 2.3 MB installed, much lighter than Electron-based launchers. Vermouth is free under the MIT license and Linux-only, with packages for several distributions plus Flatpak and AppImage. It is a young project, so expect fewer features and a smaller community than older launchers.

Best for: KDE Plasma users who want a small native launcher for Windows, Steam, GOG and retro games.
