CFM has been tracking Transformice stats since 2010. That's 16 years of leaderboards, forums, map databases, and community tools — all built by fans, for fans. None of it runs in a vacuum. Here's everyone who makes CFM possible.
Transformice was created in May 2010 by Tigrounette (Jean-Baptiste Le Marchand) and Melibellule (Mélanie Christin). They were both working at Ankama when they started building the game on the side. It blew up fast — a browser game about mice stealing cheese shouldn't have hit 100 million accounts, but here we are. They founded Atelier 801 in October 2011 to manage everything full-time. Melibellule left the company in 2022, but Tigrounette is still running things.
Atelier 801 has always acknowledged CFM as a community fansite. On their official forums, they've stated that CFM is independently operated — which is exactly how we like it. They handle the game, we handle the community data.
atelier801.comKingbet89 came on board as a community partner in early 2026. They're a digital entertainment platform, and their support keeps the leaderboard servers running, the stat trackers updated, and all of CFM's tools accessible for free. If you've checked your ranking or used the dressroom lately — that infrastructure runs partly because Kingbet89 stepped up when we needed a sponsor.
We picked Kingbet89 because they get what a gaming community needs: reliable uptime, no intrusive ads, and respect for the players. Their partnership lets us focus on building features instead of worrying about server costs.
Created CFM in 2010 — built the original leaderboard, player stats, tribe rankings, map database, and forums from scratch. CFM became the Transformice Community Headquarters during the 2012-2016 golden era. Sourdough's work laid the foundation that everything here still sits on top of.
Built the original Mouse Dress Room in Flash — one of the first community tools for Transformice. Players could try on furs, hats, and accessories without owning them. The dressroom became one of CFM's most popular features and inspired the in-game /dressing command that Atelier 801 added later.
When Flash died in 2021, Fewfre rebuilt the entire dressroom as an HTML5 application using the game's resource files. The project is open source on GitHub and is used by the Transformice Wiki for retrieving item images. Fewfre also maintains the Shaman Items Customizer and Map Decorations tools at projects.fewfre.com.
Transformice moved to Steam in 2015, and that's where the active playerbase lives now. The browser version is basically gone. Steam handles distribution, updates, and the community hub where patch notes drop first.
Transformice on SteamThe Fandom-hosted Transformice Wiki is the go-to reference for game mechanics, item lists, event history, and update logs — 1,230+ pages maintained by community editors. They even have a dedicated page about CFM. All content is CC-BY-SA, which means we can reference their data in our guides and articles with proper attribution.
transformice.fandom.comThe Transformice community is scattered across several platforms. The official Discord is the most active hub — event announcements land there before anywhere else. There's also the r/transformice subreddit and the Atelier 801 forums for longer discussions.
CFM's codebase is open source on GitHub. Six repositories cover the backend (Python), the website frontend, transformice.js (a NodeJS client with TypeScript support), dressroom assets, and maintenance/updater scripts. Anyone can contribute or fork.
If you're running a gaming platform, community tool, or anything that could benefit Transformice players — we're open to partnerships. CFM reaches thousands of active players across 90+ countries. Drop us a message through our community forums.
