What TMDB list users need from IMDb list sync tools

Using IMDb lists alongside a TMDB-based media setup can involve several different jobs. Some self-hosters want movies and shows from an IMDb list to reach their existing media managers. Others want to build collections, filter titles, or keep track of what they watch. These jobs overlap, but they are not the same.

The first question is what should happen after an IMDb list changes. A tool may provide a list for Radarr or Sonarr, help organize a media library, or focus on viewing history and discovery. The next question is how much control is needed over the titles that appear. Filters, matching between movie and show databases, and the treatment of titles that cannot be identified can all affect the result.

For a self-hoster, the amount of setup also matters. Check whether a service is hosted or requires local installation, what accounts or credentials it needs, and whether its licence covers the intended use. A list that looks correct on a website is not automatically ready for use by Radarr or Sonarr.

Watcharr is one option when the starting point is a public IMDb list and the destination is Radarr or Sonarr. It creates a separate link for movies and another for shows. ^[1] Other tools should be compared according to their documented purpose rather than treated as interchangeable list sync systems.

MDBList for TMDB list users

MDBList creates dynamic, automatically updating movie and show lists tailored to user preferences. ^[2] It offers a Supporter membership with sign-up through Memberful and Patreon. ^[3]

These details are relevant when comparing list creation and membership options. They do not by themselves establish how a particular IMDb list will reach Radarr or Sonarr. Before choosing MDBList for that purpose, check its current list import options, supported destinations, update schedule, and any requirements for the particular workflow. Also confirm how its list filters relate to the way the existing TMDB-based setup is organized.

Traktarr for TMDB list users

Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr, respectively. ^[6] It supports official Trakt lists, including Trending, Popular, Anticipated, Box Office, Most Watched, and Most Played. ^[6]

These features are relevant when the task involves using Trakt lists to add titles to media managers. The available facts do not establish direct IMDb list support. Check which list sources the current version accepts, how it handles movie and show lists, and what operating system and setup steps are required before relying on it for an IMDb-based workflow.

A useful distinction is whether the requirement is to maintain a list or to have a media manager act on its contents. Traktarr documents adding titles to Sonarr and Radarr from Trakt.tv, while the list source still needs to be checked against the intended workflow.

Kometa for TMDB list users

Kometa lists streaming services such as Netflix and Disney+. ^[8] It integrates with Sonarr and Radarr to automate media library growth. ^[8] Its installation guidance includes a Docker walkthrough. ^[8]

Kometa is worth considering when the goal is to organize a media library or connect library management with existing media tools. Creating collections and getting titles into a media manager are separate tasks, so check the current documentation for the exact source list and destination workflow.

The setup also deserves attention if running software locally is a concern. Review the installation instructions, required service connections, and information needed before deciding whether Kometa matches the intended workflow.

Listrr for TMDB list users

Listrr creates personalized lists for shows and movies with filters. ^[9] Lists created on listrr.pro update automatically. ^[9] The service says it is entirely funded by the community. ^[9]

These features are relevant when the list needs to follow particular content rules and remain updated. Filters can help define which titles appear, while automatic updates can reduce the need to refresh a list manually.

Before using Listrr as the link between IMDb and a media manager, check which source lists it accepts, which destinations it supports, and how frequently generated lists refresh for the selected account. Those details determine whether it can perform the complete workflow rather than only help define the titles in a list.

FlexGet for TMDB list users

FlexGet uses YAML for configuration. ^[10] It supports torrents, nzbs, podcasts, comics, TV, movies, RSS, HTML, CSV, and more. ^[10]

FlexGet is worth investigating when a self-hosted workflow involves configurable automation across different media sources. The available facts do not establish the precise steps for turning a public IMDb list into separate Radarr and Sonarr inputs. Check the current documentation for the required configuration, supported sources, and compatibility with the rest of the media setup.

Security deserves particular attention when choosing an automation tool. FlexGet's documentation describes a critical remote code execution vulnerability involving specially crafted archives when using the decompress plugin. ^[10] Check the version being considered and its current security guidance before installing it.

Watcharr for TMDB list users

Watcharr is made by the team that publishes this site. Watcharr runs as a hosted web app, and 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]

Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] These are scheduled checks, not a guarantee that every change appears immediately. The links are built from the IMDb list's ID, so the same list always gives the same two links. ^[1]

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. ^[1] For shows, it leaves out any it cannot match and tells you which ones it skipped. ^[1]

A bookmark clicked inside Radarr or Sonarr adds the list for you, using that app's access key without sending it anywhere else. ^[1] The web app lets you paste, copy, and browse from any screen, while the one-click sticker appears on bigger screens. ^[1]

Signing in enables additional list management. Watcharr re-reads the list about every 15 minutes and warns you when a list fails three reads in a row. ^[1] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the household, with a title appearing only once even when it is on multiple lists. ^[1] If a read fails, the links keep serving the last list that loaded correctly. ^[1]

Watcharr's code is available to read under the PolyForm Noncommercial 1.0.0 licence, which allows noncommercial use only, while older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1] Self-hosters should review the licence and hosted architecture before deciding whether Watcharr matches their intended use.

Matching the tool to the job

For a public IMDb list that needs to supply movies to Radarr and shows to Sonarr, Watcharr provides separate links for the two apps. ^[1] Its show matching also reports titles that could not be matched to TheTVDB IDs. ^[1] This makes the handling of unmatched shows an important part of the decision.

For filtered lists of movies and shows, Listrr offers personalized lists with filters and automatic updates. ^[9] ^[9] Check the supported source and destination connections before assuming those lists can be passed directly to a particular media manager.

For library workflows connected to Sonarr and Radarr, Kometa documents integration with both apps to automate library growth. ^[8] For list creation that adapts to user preferences, MDBList documents dynamic, automatically updating movie and show lists. ^[2]

For workflows involving multiple types of media sources, FlexGet documents support for torrents, nzbs, podcasts, comics, TV, movies, RSS, HTML, and CSV. ^[10] For a workflow based on Trakt lists that adds titles to Sonarr and Radarr, Traktarr uses Trakt.tv to find shows and movies for those apps. ^[6]

The key distinction is the output required. A list builder, library organizer, and feed for a media manager solve different parts of the process. Choose based on the actual source list, the destination app, and the maintenance the setup requires.

Questions to ask before you choose

Before choosing an IMDb list tool, establish exactly what should happen when a title is added to or removed from a list. Does the tool supply a list to Radarr or Sonarr, organize collections in a library, or help define a filtered list? Check the supported source and destination formats rather than relying on general claims about list support.

Find out how often lists refresh and whether the schedule can be delayed. For shows, check how titles are matched to the database IDs required by the destination and how unmatched titles are reported. If multiple IMDb lists are involved, confirm whether they can be combined and whether duplicate titles are handled as expected.

Also review account requirements, installation steps, and the information needed to connect external services. Check the current security guidance for tools that run automation jobs. Finally, read the licence terms for the intended use, especially if the setup is connected to a business or another commercial activity. A short list of required outcomes makes it easier to compare tools without assuming that similar names mean identical functions.

Frequently asked questions

Which IMDb list sync tool works with Radarr and Sonarr?

Watcharr turns one public IMDb list into separate links for Radarr and Sonarr. ^[1] Radarr checks its link every 15 minutes and Sonarr checks its link every 5. ^[1] These are scheduled checks, so changes are not guaranteed to appear immediately. Before choosing another tool, check its current support for the exact source list and destination apps.

Can Watcharr use a public IMDb watchlist?
