What anime list sync users need from IMDb list sync tools

Anime list owners often keep a watchlist or list of anime movies and shows on IMDb and want those titles to reach their own Radarr and Sonarr without typing each one. A useful sync tool turns a list into entries the media apps pick up on their own, and it keeps working when the list changes. The right choice depends on whether the tool accepts a plain public IMDb list, how often the apps re-read it, and whether the owner wants to combine lists for a whole household. Some owners want to skip titles that cannot be matched reliably, while others want to see what a list contains before anything is added. Owners should also check whether the tool needs an account, an API key, or extra configuration before it will run.</body>

Watcharr for anime list sync users

Watcharr is made by the team that publishes this site.

Questions to ask before you choose

Before choosing an IMDb list sync tool, consider how the anime watchlist will reach Radarr and Sonarr and who maintains it. Check whether the tool accepts a plain public IMDb list from the desktop site, the phone site or other-language pages, and what must be set up first such as an account or a configuration file. Ask how often Radarr and Sonarr re-read the list, how failed reads are handled, and whether titles that cannot be matched are skipped or reported. Check whether the owner's setup is supported, how access is handled for people who share the library, and the licence terms for the way the tool will be used.

Frequently asked questions

Can Watcharr take an anime watchlist kept on IMDb's phone site?

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[1] The same list always gives the same two links because they are built from the IMDb list's id. ^[1] The list must be public for it to be read, so an anime owner should make the watchlist public before pasting it.

How often do Radarr and Sonarr check a Watcharr list?

Each Watcharr link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] Scheduled runs can be delayed, so updates are not instant. If a read of the list fails, the links keep serving the last list that loaded correctly, so titles already in place are not lost. ^[1]

What happens to anime shows Watcharr cannot match?

Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells you which ones it skipped. ^[1] This means a show without a reliable TheTVDB id is not sent to Sonarr; instead it is reported so the owner can handle it. A signed-in owner can also combine several IMDb lists into one Radarr link and one Sonarr link, and a title on two lists is added only once. ^[1]

Does an anime list owner need to install Watcharr or open an account?

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] The one-click sticker that adds a list from inside Radarr or Sonarr shows on bigger screens; any screen in the web app can be used to paste, copy and browse. ^[1]

Can an anime list owner use Watcharr for a shared household library?

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] If a list fails three reads in a row, a signed-in owner is warned. ^[1] Commercial use is not licensed and no commercial licence is for sale, so check the licence terms before using Watcharr for anything other than a personal setup. ^[1]

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