Side by side

What it does

A self-hosted file storage and sharing server with spaces, permissions, public links, full-text search, WebDAV and online editing through Collabora or OnlyOffice.

A Windows search launcher opened by double-pressing Ctrl, with pinyin file search, full-text search of Office and PDF files, clipboard history, plugins and an MCP server.

Watch out

The project is little more than a year old with a small team, so its long-term support is unproven next to Nextcloud or ownCloud.

Created in October 2026 and mainly aimed at Chinese-speaking users.
