## What it is
Hydrus Network is a desktop media management application that organizes large file collections with tags instead of folders, in a booru-style interface. It can import files from disk and websites, download and parse tags via user-made downloaders, and share tags anonymously through user-run servers.

## Use cases
- organize a large personal image and video collection with tags
- find files in a 10,000+ file media library
- download images and tags from websites automatically
- subscribe to gallery searches to keep up with new files
- share tags anonymously with other users via a public server
- manage a personal booru-style media database offline

## When to choose
- you have a huge media collection and folders are no longer workable
- you want tag-based browsing like a booru site but on your desktop
- privacy matters and you want software that never phones home
- you want automated downloading and tagging from websites

## When to avoid
- you want a polished, simple, beautiful media manager
- you need a lightweight tool for small collections
- you prefer a folder-based file manager
- you need a multi-user commercial DAM system
