What Radarr and Sonarr operators need from IMDb list sync tools

Radarr and Sonarr operators usually want titles from an IMDb list to reach the right app without being copied by hand. Movies belong in Radarr and shows belong in Sonarr, so a setup that uses both needs a tool that keeps the two apart. Many households also share one list between several people, so it helps to know whether a tool can combine lists. Lists change over time, which makes it important to know how a tool re-reads a list and how often it does. A title that a tool cannot match may never reach the app, so it helps to know whether a tool reports what it skipped. Some tools also ask for an app's API key, a password-style key the app uses to accept requests, so it is worth deciding how much access you are comfortable giving any tool.

Watcharr for Radarr and Sonarr operators

Watcharr is made by the team that publishes this site.

Questions to ask before you choose

Does the tool split movies and shows into separate links for Radarr and Sonarr, or does it send both to one place? Check how often each app re-reads the list, since that sets how long a new title can take to appear. Ask what happens when the list cannot be read, and whether the tool keeps the last good copy or shows nothing. If you share a list with others, check whether one link can cover the household. Look for a tool that tells you which titles it skipped. Compare what each option costs, using the fee table above and each option's own page. For Watcharr, the code is under the PolyForm Noncommercial 1.0.0 licence, and commercial use is not licensed. ^[1] ^[1]

Frequently asked questions

Which IMDb list sync tool should Radarr and Sonarr operators compare first?

Then compare how often each tool re-reads a list, what happens when a read fails, and whether it tells you which titles it skipped. The fee table above shows which costs are published, and where a cost is not published, check that option's own page before deciding.
