What watchlist power users need from IMDb list sync tools

Watchlist power users keep public IMDb lists of movies and shows and want those titles to reach the apps that fetch them, without copying each entry by hand. A list sync tool can read an IMDb list and hand its titles to Radarr and Sonarr. The right choice depends on how many lists are kept, how often the apps should re-read them, and whether a hosted page or a self-managed script fits. Users with several lists often want them combined into one link, and users with shows should check how titles that cannot be matched to a show database are handled. Because reads run on a schedule, the gap between reads matters, and scheduled runs can be delayed, so the stated minutes are a floor, not a promise of instant updates.

Watcharr for watchlist power users

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 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 own permission without sending it anywhere else. ^[1] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[1] 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 read of the list fails, the links keep serving the last list that loaded correctly. ^[1]

MDBList for watchlist power users

MDBList is a tool for creating dynamic, auto-updating movie and show lists tailored to your preferences. ^[2] MDBList lets you import external lists from Trakt, IMDb, Rotten Tomatoes, and other sources. ^[2] MDBList has a login or sign-up link on its site. ^[9] Check it before you choose.

Matching the tool to the job

For turning one public IMDb list into a Radarr link and a Sonarr link, Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages, and pasting one list gives the movie link and the show link. ^[1] ^[1] For lists built from many filters rather than a pasted IMDb list, Listrr creates personalized lists for shows and movies with many filters, and filters by streaming services like Netflix, Amazon, HBO, or Disney+. ^[5] ^[5] For importing an existing list, MDBList lets you import external lists from Trakt, IMDb, Rotten Tomatoes, and other sources. ^[2] For adding titles into Radarr and Sonarr from Trakt lists, Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. ^[4] For a library that is already gathered, Kometa creates collections and overlays using TMDb and IMDb. ^[8]

Questions to ask before you choose

Before choosing an IMDb list sync tool, check how a pasted IMDb list stays in step with your own watchlist and how often the apps re-read it. Ask what happens to shows a tool cannot match to a show database, since some are skipped rather than added. Check whether several lists can be combined into one link and how a failed read is handled. Ask whether the page is hosted or something you run yourself, and what the tool needs on your side. Check the licence and whether commercial use is covered, and confirm which list sources each option actually works with.
