## What family ratings keepers need from IMDb list sync tools

A family ratings keeper usually has one job in mind: keep a list of films and shows the household wants, rate what has been watched, and get the new titles into the library without retyping them. The list is often shared, so more than one person may add to it, and the same title can be added twice by different people.

Lists also change. A title is added, then removed, then added again, so a sync that only handles the first import leaves gaps. Some keepers also want existing ratings to stay with the titles, which means checking whether a tool reads them at all.

The tools below are compared on what each one reads and what it does with a list, using only what each source says. The table at the end gives the same comparison in one place.

## Watcharr for family ratings keepers

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 API key without sending it anywhere else [^1].

It accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages [^1]. The links are built from the IMDb list's id, so the same list always gives the same two links [^1]. It 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 shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer [^1].

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 [^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]. The hosted version needs nothing to install and no account [^1].

## MDBList for family ratings keepers

MDBList is a tool for creating dynamic, auto-updating movie and show lists tailored to user preferences [^2]. It offers a Supporter membership [^3]. The sources for this page do not describe how a list from MDBList reaches Radarr or Sonarr, so check that on the tool's own pages before choosing it.

## Listrr for family ratings keepers

listrr.pro creates personalized lists for shows and movies with a set of filters [^9]. It allows creation of lists that exclusively contain Anime [^9]. Donors benefit from some extras on listrr.pro [^9]. Its lists are built from filters on the site, so a keeper who already has a list on IMDb should check how that list would be brought in, since the sources for this page do not say.

## FlexGet for family ratings keepers

FlexGet is equipped with a validator that tries to guide anyone who makes a mistake [^10]. It lets you manage and track series and/or movies directly from Trakt, TheTVDB or IMDb [^10]. It can be run in daemon mode [^10]. Check the tool's own pages for what setup involves before choosing it.

## Traktarr for family ratings keepers

Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr [^5]. It supports private lists [^5]. It requires Python 3.5 or newer [^5]. Because Traktarr's source names Trakt as the place it finds titles, a list kept on IMDb would need checking before it could be used with Traktarr [^5].

## Matching the tool to the job

Watcharr gives one link for Radarr with the movies and one for Sonarr with the shows from one public IMDb list [^1], and for signed-in households it combines several IMDb lists into one pair of links [^1].

For lists built from filters rather than kept by hand, listrr.pro creates personalized lists for shows and movies from a set of filters [^9]. For lists kept on IMDb, Watcharr reads a public IMDb list and gives one link for Radarr and one for Sonarr [^1]. For auto-updating lists tailored to preferences, MDBList creates dynamic, auto-updating movie and show lists [^2].

For a list kept on Trakt that a separate program adds to Radarr and Sonarr, Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr [^5]. FlexGet can be run in daemon mode [^10].

For tracking what a household watches, Simkl tracks TV shows, anime, and movies [^6], and Ryot provides support for tracking media consumption, fitness progress, and daily habits [^7]. For arranging a library into collections, Kometa can create collections based on networks, studios, genres, actors, and decades [^8].

## Questions to ask before you choose

Ask where the family list lives and whether the tool reads that site or asks you to rebuild the list inside it. Check whether more than one person can add to the list, and what happens when the same title appears twice.

Ask what the tool needs before it works: an account, a configuration file, or a machine left running. Ask how often it sends new titles to Radarr or Sonarr, since that decides how quickly an addition shows up.

Check what happens to ratings a family has already given, and whether the tool reads them or only the titles. Ask how a failure is handled, and whether the last working version of the list stays in place.

Finally, check the cost terms: what a free option covers, what a paid option adds, and whether the licence allows the use you have in mind. Watcharr's code is available to read under the PolyForm Noncommercial 1.0.0 licence, and older versions remain under MIT [^1].

## Frequently asked questions

### Can Watcharr take an IMDb list and split it into movies and shows?

Yes. 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 need an IMDb account or a login?

The hosted version needs nothing to install and no account [^1]. Signing in is optional and adds features: it re-reads your list about every 15 minutes and warns you when a list fails three reads in a row [^1]. Signing in is optional, so the hosted version needs no account to use. Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household. [^1]

### What happens when two family lists contain the same film in Watcharr?

For signed-in users, a title that is on two lists is added only once when several IMDb lists are combined into one Radarr link and one Sonarr link [^1]. If a read of the list fails, the links keep serving the last list that loaded correctly [^1]. Check how other tools handle duplicates, because this page's sources do not describe that.

### Is Watcharr free to use?

The sources listed for this page state no price for Watcharr. Commercial use is not licensed, and no commercial licence is for sale. [^1] Its code is free to read, but the current licence covers only noncommercial use, and older versions remain under the MIT licence. [^1] Check the licence terms before using it for anything beyond a personal list.

### What should a family check in MDBList before relying on it?

MDBList is a tool for creating dynamic, auto-updating movie and show lists tailored to user preferences [^2]. It offers a Supporter membership [^3]. The sources for this page do not describe how MDBList hands a list to Radarr or Sonarr, so check that on its own pages, along with whether family members can share a list.

Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. [^1] - [Visit Watcharr](/go/start-watcharr)
