Getting Started

Introduction

Cross-seeding is the term used for downloading a torrent from one tracker and then using that data to seed across different trackers. Generally, this is not against the rules, but you should always check and abide by your trackers' rules.

Since you already have the torrent's files, this results in zero download and instant seeding. This is a great way to build ratio (especially on your new trackers) and contribute to the torrenting community.

info

This software is designed to work mainly with private trackers. If you are attempting to cross-seed on public trackers, please see our FAQ entry for details before proceeding.

danger

Certain cross-seed configurations can result in downloading an excessive number of torrent files in a short amount of time. Trackers may, as a result, forbid this or require specific settings to minimize this behavior as much as possible.

See this FAQ post for details

Now we will install cross-seed and run our first search.

Installation

tip

If you are not already using Docker, and/or especially if you are on Windows, it is not recommended to install Docker specifically for cross-seed. Use one of the other methods (npm or yarn) which we refer to as running "natively".

with Docker

docker run ghcr.io/cross-seed/cross-seed --version

with npm

Requires node 16 or greater.

npm install -g cross-seed
cross-seed --version

with yarn

Requires node 16 or greater.

yarn global add cross-seed
cross-seed --version

with Unraid

In Unraid, you can install cross-seed from Docker Hub with the Community Applications app. Check out the Unraid guide for details.

tip

Docker users can skip ahead to Scaling Up.

To get started, you can use CLI.

For CLI commands, a basic example is below:

# one liner
cross-seed search --torrent-dir /path/to/dir/with/.torrent/files --output-dir . --torznab https://localhost/prowlarr/1/api?apikey=12345
# readable
cross-seed search \
--torrent-dir /path/to/dir/with/torrent/files \ # folder containing .torrent files
-o . \ # any directory, cross-seed will put its output torrents here
--torznab https://localhost/prowlarr/1/api?apikey=12345 # any valid torznab link, separated by spaces

If you were lucky, you've already got your first cross-seed in your current directory!

caution

cross-seed, by default, is particular about the contents of torrents you feed it. It will ignore torrents with non-video files in them, and it will ignore torrents that look like single episodes.

Use these command line flags to override the default: --include-episodes --include-non-videos

These command line arguments are always configurable in the config.js file (generated with gen-config). You won't have to specify them if they are set unless you wish to override the settings temporarily.

Below we will cover the configuration process.

Scaling Up

Searching like the above is nice, but it's pretty manual and not very useful in practice. In this section, we'll set up a configuration file. A configuration file is not necessary to use cross-seed, but it makes things a lot easier.

without Docker

Create and edit your config file

Start by running the following command.

cross-seed gen-config

After that, you will find an autogenerated config file at ~/.cross-seed/config.js or AppData\Local\cross-seed\config.js. Open this file in your editor of choice, and start editing.

tip

The config file uses JavaScript syntax. Each option in the config (and each element in a list) must be separated by a comma, and make sure to wrap your strings in "quotation marks" or array (multiple strings) objects in []'s

The only required options are torznab, torrentDir, and outputDir.

tip

There are many other config options available that you should thoroughly look through to achieve your desired results.

Once you've finished with your config file, the following command can get you started running a full scan of your torrent directory!

with Docker

Set up your container

With Docker, any paths that you would provide as command-line arguments or in the config file should stay hardcoded. Instead, you can mount volumes to the Docker container.

  • /config - config dir (this follows a common Docker convention)
  • /torrents - your torrent input dir
    • usually set to your rTorrent session dir, Deluge state dir, Transmission torrents dir, or your qBittorrent BT_backup dir
  • /cross-seeds - the output dir. People sometimes point this at a watch folder. If you use

Create or open your existing docker-compose.yml file and add the cross-seed service:

version: "2.1"
services:
cross-seed:
image: ghcr.io/cross-seed/cross-seed
container_name: cross-seed
user: 1000:1000 # optional but recommended
ports:
- "2468:2468" # you'll need this for daemon mode only
volumes:
- /path/to/config/folder:/config
- /path/to/torrent_dir:/torrents:ro # your torrent clients .torrent cache, can and should be mounted read-only (e.g. qbit: `BT_Backup` | deluge: `state` | transmission: `transmission/torrents` | rtorrent: session dir from `.rtorrent.rc`)
- /path/to/output/folder:/cross-seeds
- /path/to/torrent/data:/data # OPTIONAL!!! this is dataDir path (for data-based matching) - will need to replicate your torrent client's container path (like Arr's do)
command: search # this enables the search mode, change to daemon to specifically run the daemon
restart: no # make sure to not enable it in search mode, otherwise it will keep rerunning constantly

Create a config file

When you run the container the first time, it will create a config file at /config/config.js. Open this file in your favorite editor. Since you've already configured your volume mappings, the only required config option is torznab.

tip

There are many other config options available that you should thoroughly look through to achieve your desired results.

Once you set that up, you can run your Docker container and it should get started running through a full scan of your torrent directory!

Next Steps

cross-seed has two subcommands: search and daemon.

  • search will scan each torrent and dataDir (optional) you provide and look for cross-seeds, then exit.

  • daemon will run indefinitely. It can be configured to run searches periodically, watch RSS, and be triggered to search for newly finished downloads.
