Question 1

Is IMDb Watcharr free?

Accepted Answer

Yes. IMDb Watcharr has no paid tier and no payment set up anywhere in the app. It is free to use, and the source is available on GitHub so it can be self-hosted for free too. It is built as a personal, non-commercial tool: IMDb's own API terms forbid public or commercial use of its data.

Question 2

Do I need an account to use IMDb Watcharr?

Accepted Answer

No. Paste a public IMDb watchlist or list URL and get two working links back immediately, no sign-up required. Signing in with Connections is optional, and it only changes one thing: it puts that feed on the automatic refresh schedule, re-checked roughly every fifteen minutes instead of staying on its original snapshot.

Question 3

How do I add an IMDb list to Radarr?

Accepted Answer

In Radarr, open Settings, then Lists, then Add List, switch to Advanced, and choose RSS List. Paste the Radarr URL that IMDb Watcharr generated for your list. It is derived from the IMDb list itself, so it never changes and never needs replacing later.

Question 4

How do I add an IMDb list to Sonarr?

Accepted Answer

In Sonarr, open Settings, then Import Lists, then Add List, switch to Advanced, and choose Custom List. Paste the Sonarr URL that IMDb Watcharr generated. It is a separate link from the Radarr one, since Sonarr needs TVDB show data rather than the movie data Radarr reads.

Question 5

Why is a show missing from my Sonarr list?

Accepted Answer

Sonarr needs a TVDB id for every show, and IMDb Watcharr resolves those through TVMaze, but not every IMDb title maps to one. Any show it cannot match is left out of the Sonarr list rather than passed along broken, and the app reports how many titles were skipped on each sync.

Question 6

How is IMDb Watcharr different from adding an IMDb list to Radarr or Sonarr directly?

Accepted Answer

Sonarr removed its built-in IMDb list import in 2025, and Radarr's IMDb list-ID import stopped working after IMDb changed its export format. IMDb Watcharr fills that gap: a GitHub Actions runner does the IMDb fetch, and IMDb Watcharr republishes it as one Radarr RSS feed and one Sonarr Custom List from a single pasted URL, keeping the last good snapshot if a sync ever fails.

Question 7

Does IMDb Watcharr work offline, or can I self-host it?

Accepted Answer

It can't run offline. Creating a feed needs the live site, and refreshing a claimed feed needs the scheduled GitHub Actions sync. But the code is source-available on GitHub, so you can self-host the whole thing, Cloudflare Worker, D1 database, and sync job, instead of using the hosted version.

Question 8

Why does a list I just pasted return an error?

Accepted Answer

A brand-new list is not instant. The site cannot fetch IMDb directly, so a freshly pasted URL is queued, and the Radarr and Sonarr routes answer 503 until the next sync fills the list in. Once it has synced, the two links keep serving that snapshot even if a later sync fails.
