What Kometa, Listrr is built for

Kometa's pages describe a tool that lets you customize media library metadata, collections and overlays with granular control. [1] Its sources say it builds collections and overlays using TMDb and IMDb. [1] The pages name the kinds of collections it can make: from trending and popular content [1], from networks, studios, genres, actors and decades [1], and from streaming services such as Netflix and Disney+. [1] Its sources say it provides pre-made modular collections and overlays [1] and lets you customize artwork, titles and summaries. [1]

Listrr's pages describe a site that creates personalized lists for shows and movies with many filters. [2] Its sources say the lists can be filtered by streaming services such as Netflix, Amazon, HBO or Disney+ [2] and by ratings and the amount of votes. [2] The pages say it can create lists that contain only anime [2] and that every list gets updated automatically. [2] Its sources say the site is entirely funded by the community. [2]

What Watcharr is built for

Watcharr is made by the team that publishes this site. It is a hosted website; the hosted version needs nothing to install and no account. [3]

You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [3] The links are built from the IMDb list's id, so the same list always gives the same two links. [3] Watcharr accepts any public IMDb watchlist or list, whether it comes from the desktop site, the phone site or IMDb's other-language pages. [3]

Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. [3] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells you which ones it skipped. [3] If a read of the list fails, the links keep serving the last list that loaded correctly. [3]

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. [3] 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. [3] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, and commercial use is not licensed and no commercial licence is for sale. [3] [3]

[3] Each link acts like a small Radarr or Sonarr server, which is how Radarr and Sonarr read your requests from it. [3] The claims for Watcharr do not mention Plex, so check how your library fits.

Things to check before you choose

Ask what each tool costs to run, because none of the sources publishes a price. Ask whether a tool runs on your own machine or is hosted for you. Kometa's sources describe a local setup with configuration files [1], while Watcharr's claims describe a hosted one. [3]

Ask how often lists refresh and what happens when a refresh fails. Ask whether a tool can reach your Radarr or Sonarr credentials, and what it does with them. Ask whether commercial use matters to you: the facts for Kometa and Listrr say nothing about it, so check each, while Watcharr's claims say its licence does not cover commercial use. [3]

[3] If you want a set schedule with no manual work, Watcharr's claims say Radarr checks every 15 minutes and Sonarr every 5. [3] If you run your own setup where credentials stay in your configuration files, Kometa's sources describe that. [1]
