What lightweight tracker seekers need from IMDb list sync tools

Lightweight tracker seekers usually want a short path from a list they already keep on IMDb to the titles they want in Radarr and Sonarr, the apps that handle movie and show requests. They tend to care less about dashboards and more about how many steps the setup takes and whether the list reaches both apps.

The list source matters first. Some tools read a public IMDb list directly, while others start from a list kept on another service or built inside the tool, so check which one you already use. Next, look at phone and desktop access, since many people add titles from a phone and the list link may come from either.

Timing is the third question, because a list is read on a schedule and new titles can take a while to appear. Finally, consider what happens when a list cannot be read, since tools can handle that differently.

Watcharr for lightweight tracker seekers

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. ^[1] Each link acts like a small Radarr or Sonarr server, and each app reads it on its own schedule: Radarr 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 hosted version needs nothing to install and no account. ^[1] It accepts any public IMDb watchlist or list, including ones from the phone site. ^[1] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. ^[1] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household, and a title on two lists is added only once. ^[1]

Traktarr for lightweight tracker seekers

Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr respectively. ^[2] Its page includes the label 'Add a single show to Sonarr', so check its own documentation for how that works. ^[2] Check Traktarr's own documentation for how it handles public lists. Check its own documentation for how it handles a list that cannot be read.

MDBList for lightweight tracker seekers

MDBList describes itself as a tool for creating dynamic, auto-updating movie and show lists. ^[3] It lets you import external lists from Trakt, IMDb, Rotten Tomatoes and other sources. ^[3] Check its own documentation to see how its lists reach Radarr or Sonarr.

Matching the tool to the job

A seeker who wants one public IMDb list split into a movie link and a show link can start with Watcharr. ^[1] If a read fails, the Watcharr links keep serving the last list that loaded correctly. ^[1]

A seeker who wants to add one show at a time to Sonarr can check Traktarr's own documentation for that feature, since its page only shows the label 'Add a single show to Sonarr'. ^[2] A seeker who wants lists that update on their own can look at MDBList, which describes its lists as auto-updating. ^[3]

A seeker who wants to follow series or movies from IMDb directly can look at FlexGet, which can track them from IMDb. ^[6] A seeker who wants a service that is free on a phone can look at Trakt, which is free on web, iOS and Android. ^[5] Some jobs do not match any single option cleanly, so use the table and the questions below to compare.

Questions to ask before you choose

Does the tool read a public IMDb list, or does it need a list kept on another service? How often does it check a list, and what happens when a check fails? Will one link cover both movies and shows, or do you need two separate links? Does the tool read the list from the phone site as well as the desktop site? Will one person use the list, or the whole household?

If you plan to use the code yourself, check the licence. Watcharr's code is available under the PolyForm Noncommercial 1.0.0 licence. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]
