What anime list keepers need from IMDb list sync tools

Anime list keepers usually maintain one or more IMDb lists of series and films, and they want those titles to reach the right apps without retyping them. Radarr and Sonarr are two apps that collect titles for a media library: Radarr handles movies and Sonarr handles shows. A sync tool sits between the list and those apps, so the list stays the source and the apps pick up new entries on their own.

A few limits matter for this kind of list. Some shows may not match cleanly to TheTVDB, the show database Sonarr uses, so check what a tool does with titles it cannot match. Lists can grow long and get shared with other people in the household, so it helps to know whether one link can combine several lists. Anime seasons add new titles through the year, so how often a tool refreshes the list matters. Check whether a tool needs a sign-in or software running on your own computer before you set it up.

Watcharr for anime list keepers

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] 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, the key that lets outside tools reach it, without sending that key anywhere else. ^[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 links are built from the IMDb list's id, so the same list always gives the same two links. ^[1] The hosted version needs nothing to install and no account. ^[1]

MDBList for anime list keepers

MDBList is a tool for creating dynamic, auto-updating movie and show lists tailored to user preferences. ^[2] It offers a Supporter membership. ^[3] Check on its site how it reads an IMDb list and which apps it sends titles to.

Traktarr for anime list keepers

Traktarr uses Trakt to find shows and movies to add to Sonarr and Radarr. ^[6] It supports public lists. ^[6] Its setup includes an automatic scheduled option. ^[6] Check which list sources it accepts before you choose, since Trakt is a separate service from IMDb.

Listrr for anime list keepers

Listrr creates personalized lists for shows and movies with many filters. ^[10] Donors can get list updates every 3 instead of 24 hours. ^[10] Donors get some extras. ^[10] Check whether its lists can take an IMDb list as their source, and what the donor extras include.

FlexGet for anime list keepers

FlexGet can manage and track series and movies from Trakt, TheTVDB or IMDb. ^[11] It can run in daemon mode, which keeps it running on a computer in the background. ^[11] It works with TV, movies, and RSS feeds. ^[11] Check that you run a current release before you set it up.

Matching the tool to the job

If you keep one IMDb list and want movies and shows to reach Radarr and Sonarr separately, Watcharr is built for that job, since one link goes to each app. ^[1] If several people share one library and their lists should feed the same apps, the shared option combines them into one Radarr link and one Sonarr link. ^[1] If you want the list to refresh without a manual step, Watcharr re-reads a signed-in user's list about every 15 minutes. ^[1]

If your source is Trakt and you want Radarr and Sonarr to pull titles from it, Traktarr uses Trakt to find shows and movies to add to those apps. ^[6] If the job is automation that tracks series and movies across several sites, FlexGet can manage and track them from Trakt, TheTVDB and IMDb. ^[11] If the job is a list that refreshes more often, Listrr donors can get list updates every 3 instead of 24 hours. ^[10] If the job is collections and overlays for the library, Kometa can create collections and overlays using TMDb and IMDb. ^[9]

Questions to ask before you choose

Start with where the list lives. Does it sit on IMDb, Trakt, or another service, and does the tool read that source? Next, look at how titles reach the apps. Will movies and shows go to Radarr and Sonarr separately, and does the tool say which titles it could not match? Consider how often the list refreshes, since anime seasons add new shows through the year. Then check cost and accounts: does the tool need a sign-in, and what does it cost to use? Finally, decide who will use it. A single keeper and a household with shared lists need different things, and a tool that works well for one person may not handle several people's lists in the same way.

Frequently asked questions

Which IMDb list sync tool should anime list keepers compare first?

Start with the list source and how titles reach your apps. Watcharr takes any public IMDb list and gives one link for Radarr with the movies and one for Sonarr with the shows. ^[1] Traktarr uses Trakt to find shows and movies to add to Sonarr and Radarr. ^[6] After that, compare how often each tool refreshes the list and whether it needs a sign-in, since those details decide how much manual work stays with you.

Can Watcharr sync an anime list without an account?

The hosted version needs nothing to install and no account. ^[1] You paste a public IMDb list, and the tool accepts lists from the desktop site, the phone site or IMDb's other-language pages. ^[1] Automatic refresh is for signed-in users, who get a re-read about every 15 minutes. ^[1]

What happens to anime shows that Watcharr cannot match?

Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. ^[1] Sonarr identifies shows by those TheTVDB ids, so the list of skipped shows is the place to check what needs attention.

Can Watcharr combine several anime lists for a household?

Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household. ^[1] A title that is on two lists is added only once. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1]

Can FlexGet track series and movies from IMDb and Trakt?

FlexGet can manage and track series and movies directly from Trakt, TheTVDB or IMDb. ^[11] It can run in daemon mode, which keeps it running in the background on a computer. ^[11] Check that you run a current release and read its setup notes before you rely on it for a shared library.

Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. ^[1]
