Film club hosts keep their picks on a public IMDb list and want them to reach Radarr and Sonarr, the apps that grab movies and shows. Watcharr turns one public IMDb list into two links: one for Radarr, which gets the movies, and one for Sonarr, which gets the shows. ^[1]

What film club hosts need from IMDb list sync tools

Film club hosts usually run a club that picks a film on a schedule, and they often keep that pick on a public IMDb list. The job is to move the list into Radarr, for movies, and Sonarr, for shows, and to keep each reading current so a new pick appears when expected. Hosts also need the tool to say when a title could not be matched, so a skipped film can be checked, and to avoid adding the same title twice when a pick sits on more than one list.

The limits matter as much as the features. Some tools read lists you have signed into, some need extra setup, and some depend on another service to find titles. Hosts should check whether the tool reads public lists, private lists, or both. Hosts should also look at how many people can touch the list, whether separate links for movies and shows are wanted, and how the tool copes when a feed fails.

Listrr for film club hosts

Listrr lets you build lists of shows and movies using a wide range of filters. ^[8] It allows filtering by streaming services like Netflix, Amazon, HBO, or Disney+. ^[8]

MDBList for film club hosts

MDBList combines ratings from platforms including IMDb, TMDb, Letterboxd, Rotten Tomatoes, Metacritic, MyAnimeList, and RogerEbert. ^[2] It syncs a watchlist, ratings, and progress with Trakt, without leaving its interface. ^[2] Its site footer links to an API for developers. ^[10]

Trakt for film club hosts

Trakt is free on web, iOS and Android; the card fee is not published. ^[11] Film club hosts can check Trakt's own page for how it moves an IMDb list into Radarr or Sonarr, since the facts available here only state where it is free.

Traktarr for film club hosts

Traktarr uses Trakt to find shows and movies to add to Sonarr and Radarr. ^[4] It supports official Trakt lists such as Trending, Popular, Anticipated, Box Office, Most Watched, and Most Played. ^[4] It supports multiple authenticated users. ^[4]

Simkl for film club hosts

Simkl supports importing watch history from more than 20 services. ^[5] It includes calendar support with more than 20 calendars and iCAL sync. ^[5] It offers Free, Pro, and VIP memberships. ^[5]

Watcharr for film club hosts

Watcharr is made by the team that publishes this site. The hosted version needs nothing to install and no account. ^[1] You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. ^[1] It accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. ^[1] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's API key without sending it anywhere else. ^[1] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[1] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells you which ones it skipped. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1] If you sign in, it re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. ^[1] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household, and a title that is on two lists is added only once. ^[1] The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop, and trailer. ^[1] You can paste, copy, and browse from any screen in the web app, and the one-click bookmark shows on bigger screens. ^[1] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, and older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

Matching the tool to the job

For a shared IMDb list that reaches both Radarr and Sonarr, Watcharr gives one link for the movies and one for the shows from a single public IMDb list. ^[1] For hosts who choose picks by streaming service, Listrr lets a list be filtered by Netflix, Amazon, HBO, or Disney+. ^[8] For hosts who want ratings from many sites in one view, MDBList combines ratings from platforms including IMDb, TMDb, Letterboxd, Rotten Tomatoes, Metacritic, MyAnimeList, and RogerEbert. ^[2] For a club that already follows Trakt, Traktarr finds shows and movies through Trakt to add to Sonarr and Radarr, ^[4] and MDBList syncs a watchlist, ratings and progress with Trakt. ^[2] For seeing the plot and rating of each listed title, Watcharr opens TMDB's plot, genres, rating, backdrop, and trailer for each cover. ^[1] For hosts who keep the list current without manual work, Watcharr re-reads the list about every 15 minutes when signed in. ^[1] For hosts who add picks from a phone, Watcharr accepts any public IMDb list from the phone site. ^[1] Simkl supports importing watch history from more than 20 services. ^[5] When a list fails to load, Watcharr keeps serving the last list that loaded correctly. ^[1]

Questions to ask before you choose

Before choosing an IMDb list sync tool, film club hosts should ask whether it reads public lists, a private list, or both, since that depends on how the club shares its picks. Check how often an update runs, and what happens when a title cannot be matched or a feed fails. Ask how many people can sign in and whether one list or several lists can feed the same Radarr and Sonarr links. Confirm the update schedule, because tools differ in how quickly a new pick appears. Check the licence, since a club that uses a tool for money needs terms that allow commercial use. Ask how duplicates are handled when a title sits on two lists, and how the club is told when a title was skipped. For a list hosted on IMDb, check that the tool reads IMDb lists rather than relying on another service's lists.

Frequently asked questions

Can Watcharr turn one IMDb list into both a Radarr and a Sonarr link?

Watcharr turns one public IMDb list into two links: one for Radarr with the movies and one for Sonarr with the shows. ^[1] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[1]

Does Watcharr need an account or anything to install?

The hosted version of Watcharr needs nothing to install and no account. ^[1] A host pastes one public IMDb list and gets two links, one for Radarr and one for Sonarr, then adds each link to the matching app. ^[1] Signing in adds more: Watcharr re-reads the list about every 15 minutes and warns when a list fails three reads in a row. ^[1]

How does Watcharr handle a show it cannot match?

Watcharr finds each show's ID on TheTVDB through TVMaze and TMDB, leaves out shows it cannot match, and tells the host which ones it skipped. ^[1] This means a show without a matching id is not silently dropped, and the host can check the skipped titles separately. If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1]
