IMDb list sync tools turn one public IMDb watchlist or list into feeds that Radarr and Sonarr read, so titles are added without typing each one by hand. The main differences are what each tool accepts as input, how often the links update, and whether movies and shows are handled separately. Watcharr, made by the team that publishes this site, takes one public IMDb list and returns one link for Radarr and one for Sonarr.

What streaming enthusiasts need from IMDb list sync tools

Streaming enthusiasts who run a Plex server usually keep a public IMDb watchlist or list of titles they plan to watch. The real job is to turn that list into feeds that Radarr and Sonarr read, so movies and shows are added without typing each title by hand. Watcharr accepts public IMDb watchlists or lists from the desktop site, the phone site or IMDb's other-language pages. ^[1] Watcharr checks its links on a schedule, with Radarr checking every 15 minutes and Sonarr every 5 minutes. ^[1] Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. ^[1] Enthusiasts usually want the same list to keep giving the same links, and they want a warning when a read fails so a stale list is not mistaken for the current one. Choosing means looking at what each tool accepts as input, how often it updates, and whether movies and shows are handled separately. It also helps to check whether a title shared between two lists is added once or twice, and whether the links keep serving the last usable copy when a read fails.

Watcharr for streaming enthusiasts

Watcharr is made by the team that publishes this site. One public IMDb list gives 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 it every 15 minutes and Sonarr every 5 minutes. ^[1] It accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[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 page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. ^[1] The hosted version needs nothing to install and no account. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1]

Matching the tool to the job

For a single public IMDb list that must feed both Radarr and Sonarr as stable links, Watcharr returns one link for the movies and one for the shows, and the links are built from the IMDb list's id so the same list always gives the same two links. ^[1] ^[1] It reads on a schedule of every 15 minutes for Radarr and every 5 for Sonarr. ^[1] Anyone who keeps a list updated over time can use Watcharr's stable links with a warning when three reads in a row fail. ^[1] For building filtered lists from scratch, listrr.pro creates personalized lists for shows and movies with many filters and updates every list automatically. ^[9] ^[9] For ready-made curated lists, MDBList provides prepopulated lists such as Most Pirated Movies and IMDb Most Popular. ^[2] For watch tracking across devices, Trakt is free on web, iOS and Android. ^[4] For finding titles through Trakt.tv into the *arr apps, Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. ^[5] For a media dashboard alongside fitness and habits, Ryot monitors media consumption, fitness progress and daily habits, and offers a live demo. ^[7] ^[7] For collections driven by streaming services, Kometa can create collections based on Netflix, Disney+ and similar services. ^[8] For personalized discovery, Simkl offers personalized AI recommendations. ^[6]

Questions to ask before you choose

Before choosing an IMDb list sync tool, streaming enthusiasts should ask what input each tool accepts and whether a public IMDb list or watchlist is enough. Check how often the feeds update and what happens when a read fails, so a stale list is not served silently. Ask whether movies and shows are handled separately and whether a title on two lists is added once or twice. Check how titles that cannot be matched are reported, and whether skipped shows are named. Ask how the tool connects to Radarr and Sonarr and what those apps need set up. Also check the cost details on the service's own page, since several options publish their pricing there rather than on this page.

Frequently asked questions

Can Watcharr turn one IMDb list into separate movie and show feeds?

Yes. One public IMDb list in Watcharr gives 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 it every 15 minutes and Sonarr every 5 minutes. ^[1] What matters for a streaming enthusiast is that the two feeds stay separate and keep working when a read of the list fails, because the links keep serving the last list that loaded correctly. ^[1]

Does Watcharr need anything installed or an account?

The hosted version of Watcharr needs nothing to install and no account. ^[1] You paste a public IMDb list, and the app returns the two links. 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]

How does Watcharr report titles it cannot match?

Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells users which ones it skipped. ^[1] For a streaming enthusiast this matters because a title without a match is not forced into Sonarr, which keeps the library clean, while still naming the skipped titles so a missing show is not silently lost. If you sign in, Watcharr re-reads the list about every 15 minutes and warns you when a list fails three reads in a row. ^[1]

Can Watcharr combine several IMDb lists into one feed set?

Signed-in users of Watcharr can combine several IMDb lists into one Radarr link and one Sonarr link. ^[1] A title that is on two lists is added only once. ^[1] The same list always gives the same two links, since the links are built from the IMDb list's id. ^[1]

Which IMDb lists does Watcharr accept?

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[1] So a list that another language edition of IMDb generates still works, and a watchlist saved in a phone browser works the same way as one made on the desktop site. What is needed is that the list is public, since the tool builds its links from the list's id. That is worth confirming on the IMDb side before relying on a list that was shared privately.

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