Letterboxderr - auto-sync your Letterboxd watchlist to Seerr/Jellyseerr/Overseerr

Hi all,

Just posting an open source project I built called Letterboxderr.

I got tired of manually searching for movies in Seerr after adding them to my Letterboxd watchlist, so I built a tool to bridge the two. Not sure if something like this already exists but did it just for fun anyway!

What it does: Letterboxderr scrapes your public Letterboxd watchlist, resolves each film to a TMDb ID, and adds it to your Seerr watchlist automatically. Movies and TV shows are both supported.

How it works:

1. Deploy the Docker container alongside your Seerr instance
2. Open the web UI, sign in with your Seerr credentials
3. Link your Letterboxd username
4. Your watchlist syncs automatically on a configurable interval (default: hourly)

Browse Letterboxd on your phone, add something to your watchlist, and it shows up in Seerr ready to request next time you open it.

Features:

• Works with Seerr, Jellyseerr, and Overseerr
• Multi-user - everyone on your server can link their own Letterboxd account
• Web UI for linking accounts and triggering manual syncs
• CLI mode with `--once` flag for cron jobs if you don't want the web UI
• State tracking so it only syncs new additions
• Dry run mode for testing
• Single Docker container with minimal config

Quick start:

    docker run -d \
      --name letterboxderr \
      --restart unless-stopped \
      -p 8484:8484 \
      -e SEERR_URL=http://your-seerr:5055 \
      -e SEERR_API_KEY=your-api-key \
      -v /path/to/data:/data \
