Kermo Launcher
- Rust
- Tauri
- Svelte
- TypeScript
Rewritten from scratch from C# to Rust + Tauri to achieve maximum performance and low memory usage.
The catalog lives on a public Nextcloud share. The app installs and updates games with SHA-256 checks, tracks playtime, and runs Windows titles on Linux through Proton.

Admin Tool
KermoLauncher Admin is a separate app that publishes games into the synced Nextcloud folder with a SHA-256 delta copy. Screenshots and covers are not uploaded; the launcher fetches them from Steam.
2.0 is Tauri + Svelte. 1.x C# installs do not auto-update — install 2.0 separately. Playtime and settings stay on the same launcher.db paths as 1.x.
