Compare IMDb list sync tools for trackers that run in Docker with a sqlite database, and see how each handles lists and matches titles.

Trackers that run in Docker and keep a sqlite database usually want a simple way to turn a public IMDb watchlist or list into something those trackers can read automatically. Watcharr turns one pasted IMDb list into one link for Radarr with the movies and one for Sonarr with the shows. [^1] The right tool depends on whether the tracker reads lists directly, what matching it does, and whether it runs in Docker or is hosted.

## What sqlite and docker trackers need from IMDb list sync tools

Trackers that run in Docker and keep their data in a sqlite database, such as Radarr for movies and Sonarr for shows, usually need a simple way to turn a public IMDb watchlist or list into titles they can grab automatically. The useful jobs are splitting a list into its movies and shows, matching titles to the ids a tracker recognizes, and keeping those titles updated on a regular schedule so nothing sits stale. The limits matter too: a tool can only feed lists it is allowed to read, it only adds titles it can match, and a scheduled run can be delayed, so the update runs on a timer and never happens instantly. Docker users also care that no tracker passwords leave the machine, and that a failed read does not wipe what already loaded. Some owners want one shared link for the whole household, some want a per-app link, and some want nothing installed on their own machine at all. The right choice depends on how the lists are read, how titles are matched, and whether the owner is happy to host the tool or prefers one that runs elsewhere.

## MDBList for sqlite and docker trackers

MDBList is a tool for creating dynamic, auto-updating movie and show lists tailored to user preferences. [^2] MDBList lets users import external lists from Trakt, IMDb, Rotten Tomatoes, and other sources. [^2] MDBList's site has a Login / Sign Up link. [^7]

## Trakt for sqlite and docker trackers

Trakt is free on web, iOS and Android. [^3] Nothing on this page states how Trakt connects a tracker to a list, so a tracker owner would need to check that on Trakt's own pages.

## Traktarr for sqlite and docker trackers

Traktarr uses Trakt to find shows and movies to add to Sonarr and Radarr. [^4] Traktarr offers an Automatic (Scheduled) Setup, a setup option its source names without describing further. [^4] Traktarr can add a single movie to Radarr. [^4] Traktarr requires Python 3.5 or newer, so a Docker owner would check whether the version in the container meets that. [^4]

## FlexGet for sqlite and docker trackers

FlexGet is equipped with a validator that tries to guide users if they make mistakes. [^5] Recent FlexGet releases had a critical security vulnerability that allowed remote code execution with specially formed titles when using the exec plugin. [^5] The fix in FlexGet version 3.20.13 addresses both reported security issues. [^5] A tracker owner who runs FlexGet would confirm the running version is at or above that fix.

## Simkl for sqlite and docker trackers

Simkl tracks TV shows, anime, and movies. [^6] Simkl automatically tracks what users are watching and offers personalized AI recommendations. [^6] [^6] Nothing here states how Simkl hands a list to a tracker, so an owner would check that on Simkl's own pages before relying on it.

## Watcharr for sqlite and docker trackers

Watcharr is made by the team that publishes this site. You paste one public IMDb list and get one link for the movie tracker with the movies and one for the show tracker with the shows. [^1] Each link acts like a small tracker server, so the movie tracker checks it every 15 minutes and the show tracker every 5. [^1] A bookmark you click inside the tracker adds the list for you, using that app's API key without sending it anywhere else. [^1] The links are built from the IMDb list's id, so the same list always gives the same two links. [^1] Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. [^1] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. [^1] The hosted version needs nothing to install and no account. [^1] Commercial use is not licensed, and no commercial licence is for sale. [^1]

## Matching the tool to the job

For turning one public IMDb list into a movie link and a show link, Watcharr splits the pasted list and serves each as a small tracker server that the trackers check on a fixed schedule. [^1] [^1] For building fresh lists tailored to personal preferences, MDBList creates dynamic, auto-updating movie and show lists and imports external lists from Trakt, IMDb, Rotten Tomatoes, and other sources. [^2] [^2] For trackers that pull from Trakt rather than IMDb, Traktarr uses Trakt to find shows and movies to add to Sonarr and Radarr and offers an automatic scheduled setup. [^4] [^4] For a free tracking option, Trakt is free on web, iOS and Android. [^3] Simkl tracks TV shows, anime, and movies. [^6] It also automatically tracks what users are watching. [^6] FlexGet has a tool that checks its configuration and tries to guide users when they make mistakes. [^5] A Docker owner should match the tool to whether the tracker reads IMDb lists directly and to the matching and schedule the tracker can take.

## Questions to ask before you choose

Check whether the tool reads a public IMDb watchlist or list directly, and whether it splits the titles into movies and shows or hands the list over whole. Ask how titles are matched to the names and records a tracker recognizes, because a show without a match is skipped rather than added anyway. Check the update schedule and what happens when a read fails, since a scheduled run can be delayed and should not wipe the last good copy. Ask what runs on the owner's machine and what runs elsewhere, and whether any tracker passwords leave the setup. Where a tool is hosted, check whether an account is needed, how several lists are combined, and how a failed read is reported. Then confirm any fee and the licence terms before relying on a tool.

## Frequently asked questions

### What do IMDb list sync tools do for trackers that run in Docker with a sqlite database?

Trackers such as Radarr for movies and Sonarr for shows keep their data in a sqlite database and often run in Docker, and they need titles to come in as lists they can read on a schedule. Watcharr turns one pasted public IMDb list into one link for the movie tracker and one for the show tracker. [^1] The best tool depends on whether it reads an IMDb list directly, how it matches titles, and whether it runs on the owner's machine or elsewhere.

### Can Watcharr split a pasted IMDb list into the movie tracker and the show tracker separately?

Yes. You paste one public IMDb list and get one link for the movie tracker with the movies and one for the show tracker with the shows. [^1] Each link acts like a small tracker server, so the movie tracker checks it every 15 minutes and the show tracker every 5. [^1] Shows that cannot be matched are left out, and Watcharr tells you which ones it skipped. [^1]

### Does Watcharr keep tracker passwords on the owner's machine?

A bookmark you click inside the tracker adds the list for you, using that app's API key without sending it anywhere else. [^1] The hosted version needs nothing to install and no account. [^1] The page does not state whether Watcharr receives those API keys, so an owner can check the code under its licence for more information about how keys are handled. [^1]

### Which option is free for someone tracking on web and phones?

Trakt is free on web, iOS and Android. [^3] Trakt is free on web, iOS and Android. [^3] Simkl lists Free, Pro, and VIP membership options. [^6] The fee for Traktarr and FlexGet is not published here, so check their own pages before relying on a free option.

### What should an owner check before picking an IMDb list sync tool?

Check how the tool reads a public IMDb list and whether it splits titles into movies and shows, since not every tool states that it does. [^1] Ask how titles are matched and what happens when a read fails, because a scheduled run can be delayed and a show without a match is skipped. Check what runs in Docker on the owner's machine and what runs elsewhere, and whether any tracker passwords leave the setup. Confirm any fee, account requirement, and licence terms before relying on a tool.

Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. [^1] - [Visit Watcharr](/go/start-watcharr)
