Hydrus Network

Hydrus Network is a free, open-source media management application designed for organizing extensive personal collections of images, videos, audio, and other files. It uses a tag-based organization system rather than traditional folder hierarchies, making large libraries easier to explore. Users can import local files or download media and metadata from supported websites. Its customizable downloaders and subscriptions automate repeated searches and media collection. The application provides built-in image viewing and video playback through MPV or native Qt components. Hydrus also supports advanced searching, duplicate management, and anonymous tag sharing through user-operated servers. Available for Windows, Linux, and macOS through source installation, it emphasizes privacy, local control, and flexible media organization.
