What Plex library auditors need from IMDb list sync tools

Auditing a Plex library means more than keeping a list of titles. The practical job may be to compare a collection of wanted movies and shows with the media managed by the server, identify items that still need attention, and keep the source list useful as it changes. A tool should match the part of that job that needs attention, whether that is passing titles to media managers, organizing collections, or tracking viewing activity.

The source of a list matters. A workflow built around a public IMDb list has different requirements from one centered on a personal watch history or a list created using filters. Watcharr accepts public IMDb watchlists and lists from the desktop site, phone site, and IMDb's other-language pages. ^[1] It turns one public IMDb list into a Radarr link for movies and a Sonarr link for shows. ^[1]

Update timing also matters. A list that changes regularly needs a clear way to refresh, while a failed source read should not leave the downstream workflow without useful data. Watcharr keeps serving the last list that loaded correctly when a subsequent read fails. ^[1] Its Radarr link is checked every 15 minutes and its Sonarr link every 5 minutes, although scheduled checks can be delayed. ^[1]

Before choosing, decide whether the main task is importing titles, tracking what has been watched, shaping the library's appearance, or maintaining lists for later use. Those jobs overlap in places, but they are not interchangeable.

MDBList for Plex library auditors

MDBList has a Streaming Charts section. ^[11] Its Stremio integration combines ratings from services including IMDb, TMDb, Letterboxd, Rotten Tomatoes, Metacritic, MyAnimeList, and RogerEbert. ^[2] These details may matter when an audit involves examining media information or exploring chart-based discovery rather than simply passing an IMDb list into Radarr and Sonarr.

For a list-sync workflow, check how the current service handles the exact source list, what export or connection options are available, and how changes reach the tools that manage the library. The available facts establish several discovery and integration features, but do not establish the precise behavior of an IMDb-to-Radarr or IMDb-to-Sonarr sync. Confirm that workflow before relying on it for an audit.

Trakt for Plex library auditors

Trakt is free on the web, iOS, and Android. ^[3] ^[9]

The available facts do not specify a direct IMDb list sync into Radarr or Sonarr, nor do they establish how a particular list changes are passed to a Plex library. If Trakt is under consideration, check whether the current workflow accepts the desired source, which media managers it connects to, and whether updates are automatic or require another step. These details determine whether it can serve as the list source for an audit or should be considered for a different part of the media-tracking process.

Traktarr for Plex library auditors

Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr, respectively. ^[4] It can add a single show to Sonarr. ^[4] Traktarr supports public Trakt lists. ^[4]

Traktarr's source says it can add multiple shows to Sonarr and multiple movies to Radarr. ^[4] ^[4] Its documented source is Trakt.tv, so an auditor whose starting point is an IMDb list should verify the route from that list to Traktarr before assuming the same workflow applies. Also check the current installation instructions and scheduling behavior. The available facts establish its source and its ability to add individual titles, but do not establish every detail of bulk list handling or refresh timing.

Simkl for Plex library auditors

Simkl says it automatically tracks what you watch and offers personalized recommendations. ^[5] ^[5] Its source lists a catalog of TV shows. ^[5] These features relate to following viewing activity and discovering media, which are different tasks from sending an IMDb list to a media manager.

An auditor considering Simkl should check how it imports existing watch information, whether the desired IMDb list can be used as a source, and whether the required output can reach Radarr or Sonarr. The available facts do not confirm those particular list-sync steps. If the central requirement is to compare a public IMDb list with titles entering the media library, verify that complete path before making Simkl part of the process.

Kometa for Plex library auditors

Kometa can create collections based on networks, studios, genres, actors, and decades. ^[7] It can also customize artwork, titles, and summaries. ^[7] Its configuration files contain URLs and credentials needed to connect to services such as Plex and TMDb. ^[7]

These capabilities relate to organizing and presenting a media library. They may be relevant when an audit includes checking whether the library's collections and displayed details reflect the intended organization. They do not by themselves establish a direct IMDb list import into Radarr or Sonarr. Check how the current configuration handles the intended source and whether the goal is to add titles, maintain collections, or change how existing titles appear. Those are separate outcomes, and the required workflow depends on which one the audit needs.

Watcharr for Plex library auditors

Watcharr is made by the team that publishes this site, VLClean. Watcharr turns one public IMDb list into one link for Radarr containing movies and one link for Sonarr containing shows. ^[1] Each link acts like a small server for its receiving app, so Radarr checks it every 15 minutes and Sonarr every 5 minutes. ^[1] These are scheduled checks, not a guarantee that every change will appear at an exact time.

You can use a bookmark inside Radarr or Sonarr to add the list, using that app's API key without sending the key anywhere else. ^[1] The same IMDb list always produces the same two links because they are built from the list's ID. ^[1]

Watcharr looks up TheTVDB IDs through TVMaze and TMDB for shows, leaves out shows it cannot match, and tells you which ones it skipped. ^[1] This matters during an audit because unmatched shows should be reviewed rather than assumed to have reached Sonarr.

The hosted version needs no installation and no account. ^[1] If you sign in, Watcharr rereads the list about every 15 minutes and warns you when three consecutive reads fail. ^[1] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the household, with duplicate titles added only once. ^[1] The code is available to read under the PolyForm Noncommercial 1.0.0 licence, while older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

Matching the tool to the job

For sending titles from a public IMDb list into the existing movie and show managers, Watcharr provides separate Radarr and Sonarr links from the same source list. ^[1] Its stable links and last-good-list behavior can also help keep an established list connection consistent when a source read fails. ^[1] ^[1]

For adding titles found through Trakt.tv to the media managers, Traktarr's source says it uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. ^[4] Check the exact path from an IMDb source before choosing it for that purpose.

Simkl says it automatically tracks what you watch and offers personalized recommendations. ^[5] ^[5] MDBList has a Stremio integration that combines ratings from several media information services, including IMDb and TMDb. ^[2]

For organizing an existing library, Kometa can create collections based on networks, studios, genres, actors, and decades. ^[7] Its source describes customizing artwork, titles and summaries. ^[7]

The deciding question is what must happen after the audit finds a title. If the result should enter Radarr or Sonarr from a public IMDb list, verify the import route and refresh behavior. If the result should change library organization, focus on collection and metadata controls. If the goal is viewing history or discovery, examine the tracking and information features instead.

Questions to ask before you choose

Start with the source. Does the tool accept the public IMDb list already used for the audit, or is another list source needed? Check whether the list must be public and whether the tool accepts the exact kind of IMDb list being maintained.

Next, establish the result. Does the tool send movies to Radarr and shows to Sonarr, or does it focus on viewing activity, information, or library presentation? If shows are passed to Sonarr, ask how unmatched titles are reported and what identifier the receiving app needs.

Check update behavior before relying on the tool for recurring audits. Find out how often a list is checked, what happens when a source read fails, and whether the last successful list remains available. Scheduled checks may be delayed, so a stated interval should not be treated as a guaranteed completion time.

Consider the practical workload as well. Does the tool require installation, configuration files, a separate account, or a connection to other services? Verify which credentials are needed and how they are handled. Finally, review the current licence, any costs, and the terms for the way the library is used. For Watcharr, commercial use is not licensed. ^[1]

Frequently asked questions

Can Watcharr sync a public IMDb list with Radarr and Sonarr?

Watcharr turns one public IMDb list into a Radarr link containing movies and a Sonarr link containing shows. ^[1] Radarr checks its link every 15 minutes and Sonarr checks its link every 5 minutes, although scheduled checks can be delayed. ^[1] Shows that cannot be matched to TheTVDB IDs are skipped, and Watcharr tells you which shows were skipped. ^[1]

Does Watcharr need to be installed for a Plex library audit?

The hosted version of Watcharr needs no installation and no account. ^[1] You paste a public IMDb list into the web app and get the links for Radarr and Sonarr. ^[1] A bookmark inside either receiving app can add the list using that app's API key without sending the key anywhere else. ^[1] The web app supports pasting, copying, and browsing from any screen, while the bookmark is shown on bigger screens. ^[1]

What happens when Watcharr cannot read an IMDb list?

If a list read fails, Watcharr continues serving the last list that loaded correctly. ^[1] Signed-in users can have Watcharr reread their list about every 15 minutes, and it warns them when a list fails three reads in a row. ^[1] This behavior helps preserve the last successful list, but it does not guarantee that new changes will be available while the source cannot be read.

Can Watcharr combine several IMDb lists for one household?

Signed-in Watcharr users can combine several IMDb lists into one Radarr link and one Sonarr link for the household. ^[1] A title that appears on more than one of those lists is added only once. ^[1] This option is useful when a household maintains separate public IMDb lists but wants the receiving apps to work from combined movie and show lists.

What should be checked before using Watcharr for a commercial Plex library?

Watcharr's code is available to read under the PolyForm Noncommercial 1.0.0 licence, while older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

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