Fumohouse is an open-source game framework based on Godot, built around the use of fumos as character models. The project is a work in progress, with development updates, documentation, and a public Kanban board that tracks tasks and contributions. Its Developer Preview 3, identified as DEV 2026.09.22, is available through the releases page. The project also invites interested users to learn about joining its multiplayer testing group through an accompanying blog post.

Fumohouse provides resources for people who want to explore the framework, including documentation and access to its source control repository on GitHub. The community can connect through Discord, while the site offers status updates and project news. Fumos are produced by Gift and designed by ANGELTYPE; many of the characters represented are based on Touhou Project by Team Shanghai Alice.
