For Watcharr, one public IMDb list pasted on its page gives two links, one for Radarr with the movies and one for Sonarr with the shows. [3] Nothing is installed to use the hosted version. [3]

What Watcharr is built for

Watcharr is made by the team that publishes this site. You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [3] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. [3] Its links are built from the IMDb list's id, so the same list always gives the same two links. [3]

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. [3] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells you which ones it skipped. [3] The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. [3]
