The useful questions are how the list gets there, how often it refreshes, and whether the tool says which shows did not come through. A show that is missing from Sonarr is easy to overlook, so a tool that reports skipped shows makes any gap visible. Some trackers follow one list for everything, while others keep a separate list for each mood or each person in the house. Check whether the tool reads the list you already keep, and whether it can share that list with others. Each option below handles these jobs in its own way. ## Watcharr for series trackers 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, so Radarr checks its link every 15 minutes and Sonarr checks its link every 5. [^1] The links are built from the 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 can't match, and tells you which ones it skipped. [^1] The hosted version needs nothing to install and no account. [^1] ## Traktarr for series trackers Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. [^2] It supports official Trakt lists, such as Trending and Popular. [^2] It can add multiple movies to Radarr. [^2] Check its page for how it reports shows it cannot add, and for which list sources it reads. ## Listrr for series trackers Listrr automatically updates every list created. [^3] It filters lists by ratings and the amount of votes. [^3] Listrr also offers an API for developers. [^3] Check its page for which list sources it reads. ## MDBList for series trackers MDBList provides prepopulated curated lists such as Most Pirated Movies, Trakt Trending, and IMDb Most Popular. [^4] MDBList's site footer links to an API, alongside Reddit, Discord, Contact and Privacy Policy links. [^6] Check its page for how a list reaches Sonarr or Radarr. ## Trakt for series trackers Trakt is free on web, iOS and Android. [^5] The facts available here cover where Trakt is free to use, not how it handles lists, so check its page for list sources and sync options before you choose. ## Matching the tool to the job A tracker who wants shows from an IMDb list sent to Sonarr through a single link can look at Watcharr, which gives one link for Radarr with the movies and one for Sonarr with the shows. [^1] A tracker who wants the list to refresh without a manual step can look at Watcharr's signed-in option, which re-reads the list about every 15 minutes. [^1] A household that wants one shared list can check Watcharr's shared option, where a show on two lists is added only once. [^1] A tracker who follows Trakt-based lists can look at Traktarr, which uses Trakt.tv to find shows to add to Sonarr. [^2] A tracker who wants ideas for what to follow can look at MDBList's curated lists, such as IMDb Most Popular. [^4] A tracker who wants to narrow a list by ratings can look at Listrr, which filters by ratings and the amount of votes. [^3] ## Questions to ask before you choose Ask which lists the tool reads, such as a public IMDb list, a Trakt list, or a curated list from another site. Ask how the tool connects to Sonarr, and whether a bookmark or a manual setup gets the link in. Ask what happens to a show the tool cannot match, and whether it tells you which shows were skipped. Ask how often the list refreshes, and whether signing in is needed for automatic refresh. Ask whether a hosted page is enough or whether an install is required. Ask whether one list can be shared with the household. Finally, compare the answers side by side, since each tool's page may describe its limits in different words. ## Frequently asked questions ### Which IMDb list sync tools should series trackers compare first? Start with how each tool gets shows into Sonarr, since that decides how much you handle by hand. Watcharr gives one link for shows and one for movies from a public IMDb list. [^1] Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. [^2] Then check how each tool reports shows it skips, because a show that never reaches Sonarr is easy to miss. ### Does Watcharr need an install before it can sync IMDb lists? No. The hosted version needs nothing to install and no account. [^1] You paste one public IMDb list into the web app, and it gives you two links. [^1] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's key for access without sending it anywhere else. [^1] You can paste, copy and browse from any screen in the web app, and the one-click bookmark shows on bigger screens. [^1] ### How often does Watcharr refresh a list for signed-in users? If you sign in, Watcharr re-reads your list about every 15 minutes. [^1] It warns you when a list fails three reads in a row. [^1] If a read fails, the links keep serving the last list that loaded correctly. [^1] Sonarr checks its link every 5 minutes and Radarr every 15. [^1] ### What happens to shows that Watcharr cannot match? Watcharr looks up show ids through TVMaze and TMDB. [^1] It leaves out shows it cannot match and tells you which ones it skipped. [^1] Check that skipped list against your IMDb list, so a show you expected does not go missing without you noticing. If a list fails, the links still serve the last list that loaded correctly. [^1] ### Does Traktarr add shows from a Trakt list to Sonarr? Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. [^2] It supports official Trakt lists, such as Trending and Popular. [^2] It can add multiple movies to Radarr. [^2] Check its page for how it reports shows it cannot add, and for which list sources it reads.
