Kometa and Traktarr compared for people who run Plex with Radarr or Sonarr: what each does, what each costs, and what to check first.

VLClean is published by the makers of Askarr and Watcharr, which are compared here alongside other tools.

Kometa and Traktarr are both tools that sit next to Radarr and Sonarr, the apps that add movies and shows to a home media library. Traktarr's page says it uses Trakt.tv to find shows and movies to add to Sonarr and Radarr ^[1]. Kometa's facts on this page are limited to the ones listed in the table below, and there is no pricing fact published for it here. Watcharr, which is made by the team that publishes this site, takes a public IMDb list you paste in and gives back two links, one for Radarr and one for Sonarr ^[2]. Costs are the first thing to pin down: Traktarr's facts on this page state no price, and Watcharr's claims state no price either. Which one suits you comes down to where your lists already live and how much setup you want.

The short answer

Traktarr's page says it uses Trakt.tv to find shows and movies to add to Sonarr and Radarr ^[1]. Its page also says it needs Python 3.5 or newer ^[1]. Kometa's facts on this page cover the points shown in the table below and no more.

Watcharr, made by the team that publishes this site, takes one public IMDb list you paste in and returns one link for Radarr with the movies and one for Sonarr with the shows ^[2].

The needs each source says it meets: Traktarr's page says it uses Trakt.tv to find titles to add ^[1], and it says it supports official Trakt lists ^[1]. Watcharr's claims cover pasting a public IMDb list ^[2] and any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages ^[2].

Nothing on this page is a test result. It is what each tool's own pages and the approved claims say.

What Kometa and Traktarr are built for

Traktarr's page says it uses Trakt.tv to find shows and movies to add to Sonarr and Radarr ^[1]. Trakt.tv is a site where people track what they watch and keep lists.

Its page says it supports official Trakt lists ^[1]. It also says it supports public lists ^[1] and private lists ^[1]. Its page says it supports multiple authenticated users ^[1].

For the machine it runs on, its page says Python 3.5 or newer is required ^[1], and it says it runs on Debian OS and can work in other operating systems as well ^[1]. Its page describes an automatic scheduled mode ^[1].

For adding titles, its page says it can add a single movie to Radarr ^[1] or multiple movies to Radarr ^[1], and a single show to Sonarr ^[1] or multiple shows to Sonarr ^[1].

The facts for Kometa used on this page are the ones shown in the table below. Beyond those, its pages are not quoted here, so check its own pages for anything else you need, such as where it runs and what it costs.

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].

Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5 ^[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 IMDb list's id, so the same list always gives the same two links ^[2].

It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped ^[2]. The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer ^[2].

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

The hosted version needs nothing to install and no account ^[2]. It runs as one Cloudflare app with a Cloudflare database, plus a GitHub job that reads IMDb ^[2]. You paste, copy and browse from any screen in the web app; the one-click sticker shows on bigger screens ^[2]. Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, and older versions remain under MIT ^[2].

Ask how often you want lists read, and check each tool's pages for the schedule. Ask whether you need several people to share one set of lists, and check that too. Ask whether a tool warns you when a list stops loading, and check its pages. Ask which titles get skipped when a match can't be found, and check each tool's pages for how it reports that.
