qBittorrent on a Seedbox: Modern Torrent Client Setup

What qBittorrent Is

qBittorrent is a free, cross-platform BitTorrent client. On a seedbox you mostly use the web UI, which is one of the better-looking client UIs out there. Built-in search, RSS, IP filtering, and a categories system out of the box, no plugin hunting.

Why Pick qBittorrent on a Seedbox?

If you're new to seedboxes and don't have a strong preference, qBittorrent is the default for good reason:

• The web UI looks like a desktop app, not a 2008 web page
• Search is built in. Add a few search engines and find releases without leaving the client
• RSS and download filters built in too. No plugins required for either
• Sonarr, Radarr, Lidarr, Prowlarr all integrate cleanly
• 10 Gbit upload, so seeding stays in the green even on big libraries

Installing qBittorrent

Open the Bytesized Panel, find qBittorrent in the app catalog, click install. The panel handles the binary, picks ports, sets up the reverse proxy, and gives you a clean HTTPS URL.

Click "Open" next to qBittorrent in your panel.

First Login

Default web UI login on a Bytesized install uses the password from your account. Check the app's settings in the panel for the current credentials.

First thing to do: Tools > Options > Web UI, change the password. Even though it's behind your panel's auth, set a strong WebUI password specifically; Sonarr and Radarr will use this.

Categories Are Your Friend

qBittorrent's category system is what makes it click with Sonarr and Radarr.

Go to Tools > Options > Downloads > "Default Save Path" and set a base folder (like ~/files). Then under Settings > Downloads, enable "Automatically add torrents from..." for any watch folders you want, and create categories with their own save paths:

• tv saves into ~/files/tv
• movies saves into ~/files/movies
• music saves into ~/files/music

Sonarr and Radarr send their category in the API call; qBittorrent puts the file in the right place. Tidy library, no manual sorting.

Sonarr / Radarr Integration

In Sonarr's Settings > Download Clients > Add > qBittorrent:

• Host: internal URL from the panel (without https://)
• Port: the qBittorrent web UI port (in your panel)
• Username and Password: the WebUI credentials
• Category: tv-sonarr (or whatever category you've set in qBittorrent)

Same setup in Radarr. Test connection in Sonarr/Radarr; if it goes green, you're set.

RSS Feeds and Auto-Download

qBittorrent has a built-in RSS reader with auto-download rules. View > RSS Reader, add a feed, then Auto-Downloading Rules to set up filters.

Useful for grabbing specific shows or releases without involving Sonarr. For most people Sonarr is the cleaner workflow, but if you've got a feed Sonarr doesn't index, RSS rules cover the gap.

Built-In Search

View > Search Engine. Click "Search plugins" at the bottom, install the ones you want from the community list. Then search across all of them at once from the search tab.

Quick wins for seedbox use; less powerful than Prowlarr but doesn't need a separate app.

Common Gotchas

Sonarr says "Failed to login." WebUI password doesn't match what's in Sonarr. Update the password in qBittorrent and paste the same one into Sonarr.

Wrong save path. Categories override the default save path. Double-check the category save paths under Tools > Options > Downloads.

Tracker errors. Some private trackers want a specific qBittorrent version range. The version Bytesized ships is current; if a tracker insists on something specific, contact support.

Downloads stuck at 99%. Almost always disk full. Check your storage usage in the panel.

qBittorrent vs Alternatives

Short version, full breakdown in the client comparison guide:

• qBittorrent. Modern UI, built-in search and RSS. Best default if you're new.
• Deluge. Lighter, plugin-driven. Good if you like to tinker.
• rTorrent + ruTorrent. Most resource-efficient, but the UI is dated.

FAQ

Is qBittorrent free? Yes. Free and open source, no premium tier.

Will it work with Sonarr and Radarr? Yes. Native integration via the WebUI.

Can I run multiple instances? On a single slice, one. If you need separate clients (different VPN configs, separate categories), most people use a different client like Deluge for the second instance.

Does Bytesized restrict trackers? No. We don't filter or log tracker connections.

Will my torrents survive an upgrade or restart? Yes. Sessions and torrent data are kept in your home directory; restarts and qBittorrent upgrades don't touch them.
