People migrating from Trakt often keep their watchlists and lists on IMDb and want those lists to reach Radarr and Sonarr.

What trakt migration users need from IMDb list sync tools

People moving off Trakt often keep their watchlists and lists on IMDb and want those titles to reach a Plex media setup without re-entering each one. A useful sync tool can take an IMDb list and feed the movies and shows into Radarr and Sonarr, the apps that handle movie and show requests. The right choice depends on how a list is added, how often the tool checks it, and how titles are matched. One approach takes a single public IMDb list and returns one link for the movies and one for the shows, so the titles split cleanly between the two apps. ^[7] Another approach reads lists from sources other than IMDb, which matters to someone whose lists still live on Trakt. The refresh rate also matters, because a tool that checks a list less often can delay a new title. A tool that leaves out titles it cannot match and says which ones it skipped helps an owner keep the library accurate. Trakt migration users should check which kind of list a tool accepts, how often it checks, and how it reports titles it cannot match.

Watcharr for trakt migration 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. ^[7] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[7] Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. ^[7] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells you which ones it skipped. ^[7] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's API key without sending it anywhere else. ^[7] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[7] If you sign in, it re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. ^[7] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household, and a title on two lists is added only once. ^[7] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[7] The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. ^[7] You paste, copy and browse from any screen in the web app, and the one-click sticker shows on bigger screens. ^[7] The hosted version needs nothing to install and no account. ^[7] Watcharr runs as one Cloudflare app with a Cloudflare database, plus a GitHub job that reads IMDb. ^[7] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, while older versions remain under MIT. ^[7] Commercial use is not licensed, and no commercial licence is for sale. ^[7]

Matching the tool to the job

Questions to ask before you choose

Before choosing an IMDb list sync tool, consider where your lists currently live and which tool accepts that source. Check whether the tool takes IMDb lists, Trakt lists, or both, and how it splits a list into movies and shows. Ask how often the tool checks a list, because a longer interval can delay a new title. Check how the tool handles titles it cannot match, and whether it tells you what it left out. Ask whether the tool needs a login or an account, and what that account changes. Also check whether the tool runs on a schedule you control or needs its own hosting, and how it handles a list that stops loading. Confirm the licence and fee for the tool you pick, because costs are not published for every option here.

Frequently asked questions

Which IMDb list sync tool should trakt migration users compare first?

Trakt migration users can compare tools by where their lists currently live, how often a list is checked, and how titles are matched. MDBList syncs a watchlist, ratings and progress directly with Trakt. ^[1] Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. ^[4] Watcharr takes a single public IMDb list and splits it into one movie link and one show link. ^[7] The right choice depends on whether the lists already moved to IMDb or still live on Trakt.

Does Watcharr need Trakt to work for trakt migration users?

No. Watcharr works from public IMDb watchlists and lists from the desktop site, the phone site, or IMDb's other-language pages. ^[7] If a migrating user still has lists on Trakt, they would first move those lists to IMDb, because Watcharr reads IMDb lists. For lists still on Trakt, Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr instead. ^[4]

How often do IMDb list sync tools check a list?

Rates vary by tool and by account type. Watcharr acts like a small Radarr or Sonarr server, so Radarr checks each list every 15 minutes and Sonarr every 5. ^[7] Listrr donors get list updates every 3 instead of 24 hours. ^[6] For a signed-in Watcharr account, the list is re-read about every 15 minutes. ^[7] Check each tool's page for its own schedule, since some published rates depend on a donation or plan.

What happens when a list stops loading in a sync tool?

Handling of a failed read differs by tool. Watcharr keeps serving the last list that loaded correctly if a read fails, so the Radarr and Sonarr links keep working. ^[7] A signed-in Watcharr account also warns you when a list fails three reads in a row. ^[7] Check other tools for their own failure behaviour, because not every option here publishes what it does when a list cannot load.

What should trakt migration users check before choosing a sync tool?

Check whether the tool accepts IMDb lists, Trakt lists, or both, and how it splits a list into movies and shows. Ask how often the list is checked and what happens when a read fails. Check whether the tool needs a login or sign-up, and for Listrr whether it can make lists that contain only Anime. ^[6] Also confirm the licence and fee, because costs are not published for every option on this page, and Watcharr's commercial use is not licensed. ^[7]

Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. ^[7]
