Cullr

A small local web app for reclaiming disk space from a media server. Deleting titles in the Radarr or Sonarr web UI is slow: open a title, read the plot, go back, delete, confirm, repeat. Cullr puts the whole library on one dense poster wall sorted largest file first, shows the synopsis on hover, and deletes everything you marked in a single batch.

• Poster wall sorted biggest first, so the first choices reclaim the most space
• Hover for plot, studio, genres, rating, runtime, codec, HDR type, exact size and path
• Stackable filters: search, studio, genre, quality, year, size, drive, monitored state
• Grouping by studio, genre, quality, drive or decade, each with its total size and a mark-all button
• Drive chips show live available space and what each drive would get back from the current marks
• Batch delete through the Radarr/Sonarr API, with a confirmation list and an audit log
• Downsize instead of delete: search your indexers for a smaller copy of the same movie and let Radarr replace the big file (movies only)
• Media-Hoarder libraries read straight from its database, read-only; deleting those files is off unless you turn it on

People running their own Radarr and Sonarr (or Media-Hoarder) whose drives are filling up, and who want to decide what goes by looking at the library instead of scrolling lists.

Python standard library only, Python 3.9 or newer, no build step and no dependencies. It runs on Windows, macOS and Linux and opens in your browser. A read-only mode disables deletion on the server, and a dry-run mode logs deletes without calling the API.
