The short answer

Radarr and Sonarr are the apps that add movies and shows to a home media library, and this page is for people who run them. The approved facts for Kometa say nothing about what it does, so check its own pages before you decide.

Trakt is free on web, iOS and Android. ^[1] Its facts do not say what it does for a home library.

Watcharr turns a public IMDb list into one link for Radarr with the movies and one for Sonarr with the shows. ^[2] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[2] Watcharr's claims describe that sync to Radarr and Sonarr. The rival facts on this page do not, so check each tool's own pages for it.

What Kometa and Trakt are built for

The approved facts for Kometa describe nothing about what it does, so this page says nothing about its features. Check Kometa's own pages for what it does and how it is set up.

Trakt is free on web, iOS and Android. ^[1] Its facts describe nothing else, so check Trakt's own pages for what it does for a movie or show library and how it connects to a server.

What Watcharr is built for

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. ^[2] It accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[2] The links are built from the list's id, so the same list always gives the same two links. ^[2]

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. ^[2] If a read fails, the links keep serving the last list that loaded correctly. ^[2] 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. ^[2]

The page shows the list's covers in a row, and each one opens the title's plot, genres, rating, backdrop and trailer from TMDB. ^[2] You can paste, copy and browse from any screen in the web app. ^[2] Watcharr runs on a hosting service, with a background task that reads your IMDb list for you so nothing extra runs on your machine. ^[2]

Pricing and fees

Kometa's price is not published in the facts for this page, so check its own pages before you plan around a cost.

Trakt is free on web, iOS and Android. ^[3] The facts for Trakt give no other price and no hosting cost, so those are not published here.

Watcharr's claims do not publish a price. The hosted version needs nothing to install and no account. ^[2] No card fee or payment service is stated for Watcharr, so that part is not published here.

Setting it up with your server

The approved facts for Kometa say nothing about connecting to Plex, Radarr or Sonarr, so check its own pages for those steps. Trakt's facts say nothing about setup either.

A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's key without sending it anywhere else. ^[2] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[2] For shows, Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. ^[2]

The claims for Watcharr do not mention Plex, so check how your library fits.

Things to check before you choose

Ask where each tool runs and what it costs there. Kometa's facts give neither, so check its pages. Trakt's facts give a price on web, iOS and Android and nothing on hosting. ^[3]

Ask whether your lists are public. Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[2]

Ask what happens when a list fails to load. Watcharr's links keep serving the last list that loaded correctly. ^[2]

Ask which shows will be left out. Watcharr tells you which ones it skipped when it cannot match them. ^[2]

Ask about licence terms if you plan commercial use. Watcharr's code is available under the PolyForm Noncommercial 1.0.0 licence, and commercial use is not licensed. ^[2] ^[2]

How to choose

If you want one IMDb list for movies and another for shows, Watcharr's claims say it gives you one link for each. ^[2] If you want a list that refreshes without you doing anything, its signed-in refresh runs about every 15 minutes. ^[2] If several people share a home, combined lists are available to signed-in users. ^[2]

If you want to know whether Trakt costs anything on web, iOS and Android, its sources say it is free there. ^[1] For what Kometa does, the approved facts for this page are silent, so check its pages.
