The TMC App - The Modding Community
The TMC App
A cross-platform server browser and mod manager that runs on your machine — so it can do the two things a website physically cannot: ping servers from your connection, and put mods in your game folder.
Desktop is the target we are aiming at first — Windows, Linux and macOS. Mobile follows once those land. One Rust, Tauri 2 and React codebase either way, and none of them are released yet.
The app is not available yet, and it is not ready. There is nothing to download on any platform and nothing here can be installed today — this page describes what has been built so far. The source is public while it comes together.

Real Latency, Real Player Counts
The website can only show you what our scanner last saw, from wherever the scanner happens to live. Where it tries to do better than that, it is guessing from geography — your rough position, from your browser or from your IP address, measured against the server's — and that is a guess too: it describes a straight line on a map, not the route your packets take or the state of it right now. The app sends the game's own query packet from your device — so the player count is current, and the ping is the one you will actually get. A player in Sydney and a player in Frankfurt see different numbers for the same box, and only something running on their machine can tell either of them the truth.
Which protocol a server uses, and which port to ask, come from the same list our own scanners use — there is no second source to drift.
Profiles, Deployed Without Copying Anything
A sandbox is what other managers call a profile or an instance: a named set of mods with its own load order, its own deployment method and its own launch settings. Mods are staged once and then linked into the game folder, so switching between profiles is a link operation rather than a re-download — and the game folder is recoverable either way.
A Queue Built For Hundreds Of Files
A modpack is not one download. It is hundreds, over a home connection, on a laptop that will be closed halfway through — so every byte the app fetches goes through one queue with pause, resume, priorities and bandwidth limits.
Extensible, Without Running Anyone's Code
A plugin is data, never code. No script engine, no WASM, no "run this program" step. An installer describes file operations, a query plugin describes a packet and how to read the reply, a theme describes colours — and everything a plugin can express is something the app implements and audits itself.
The Webview Gets Data. Nothing Else
A mod description is untrusted text rendered inside a window that can call into the app. So credentials and the filesystem live in Rust, and the interface is handed data — there is no way to ask it for your token, and exactly one command accepts a path at all, which lists directory names and nothing else.
Not Available, And Not Ready
To be completely clear: you cannot download or install the TMC app today. Everything above describes what is built so far, not something you can run — and we would rather you hear that from us than find out at the end of a download page that does not exist.
