hydrus is a personal booru-style media tagger that can import files and tags from your hard drive and popular websites. Content can be shared with other users via user-run servers.
The hydrus network client is a desktop application written individuals with large media collections.
It organises your files into an internal database and browses them with tags instead of folders, a little like a booru on your desktop. Tags and files can be anonymously shared through custom servers that any user may run. Everything is free, nothing phones home, and the source code is included with the release.
