A list sync tool takes a list and adds its titles to those apps, and the right one depends on how lists are made, what gets added, and how often updates happen. Curators may keep one list for movies and another for shows, or combine several lists into one set for the whole household. Some lists change often as titles are added and removed, so it helps when the same list always gives the same two links and updates on its own. Curators should check which list sources a tool accepts, whether titles that cannot be matched are left out or reported, and what the tool needs to connect to Radarr and Sonarr. ## MDBList for home library curators MDBList is a tool for creating dynamic, auto-updating movie and show lists tailored to user preferences.

[^6] ## Questions to ask before you choose Before choosing an IMDb list sync tool, consider how titles are matched into the movie and show apps and which list sources are accepted. Check whether the tool updates a list on its own and how often, and whether a failed read keeps the last good result. Ask whether private lists are supported and whether titles that cannot be matched are left out or reported. Check which apps the tool works with, such as Radarr and Sonarr, and what it needs to connect to them. Also check the cost, whether an account is needed, and whether the same list always gives the same links. ## Frequently asked questions ### Which IMDb list sync tool should home library curators compare first? Home library curators can compare tools based on how lists are kept in sync, which apps each works with, and how titles are matched. Options differ in the list sources they accept, how often they update, and whether an account is needed, so the right choice depends on the movie and show apps the curator already uses and how its lists are built. ### Can Watcharr turn one IMDb list into links for Radarr and Sonarr? Yes, Watcharr lets 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] The links are built from the IMDb list's id, so the same list always gives the same two links. [^1] ### Does Watcharr keep serving a list if a read fails? Yes, if a read of the list fails, the links keep serving the last list that loaded correctly. [^1] If you sign in, Watcharr re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. [^1] ### How does Watcharr handle titles it 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] The page also shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. [^1] ### Can Watcharr combine several IMDb lists into one? 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] 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] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT.
