Desktop app

The TMC app is the site’s desktop client. It does what the website cannot do from inside a browser: put files into a game’s folder, measure latency to a server from your machine, and start a game as a real program.

Installing

Downloads are on the app’s page and on the GitHub releases.

• Linux — one line, no root: curl -fsSL https://raw.githubusercontent.com/modcommunity/tmc-app/main/scripts/install.sh | sh. It checks the download against the release’s checksums, installs into ~/.local, and registers the launcher entry and the tmc:// link scheme. … | sh -s -- --uninstall removes it. AppImage and .deb builds are also published.
• Windows — the setup.exe or .msi installer. The portable .exe runs without installing, and so does not register the tmc:// scheme: links from the website will not open it.
• macOS — the .dmg.

Signing in

The app signs in with a device code: it shows a short code, you approve it on the website while signed in, and the app receives its own token. It never sees your password, and you can revoke it under Account → Sessions — see Keys and integrations and, for the protocol, App API authentication.

What it does

• Mods. One-click install and uninstall for games that support it, and sandboxes — named mod profiles per game, each with its own load order and deployment method. Switching sandboxes does not re-download anything.
• Servers. A server browser with real-time latency measured from your machine, status and latency charts, RCON with history, and one-click connect where the game supports it.
• Games. Every game has its own page, and TMC’s own games are installed, updated and launched by the app, joining over UDP by default (with a setting for TCP/WebSocket) or running Solo with no server — see Games and playing.
• Friends and parties. The same friends and parties the website and the games themselves show — see Friends and parties.
