SiloRider is a command-line utility that lets you implement the POSSE model on a website. This is how it works:

The code is available on GitHub and BitBucket.

Supported Silos

Right now, the following silos are supported:


You can install SiloRider like any other Python tool:

pip install silorider

You can then check it installed correctly with:

silorider -h

You can also install from source by cloning the Git or Mercurial repository and running:

pip install -e /path/to/silorider/repo


SiloRider will need to read a configuration file in INI format. The minimum requirement is to define at least one “silo” using a silo:<name> section:

type: mastodon


This defines one Mastodon silo to which you want to cross-post entries from your blog at

You can then run:

silorider auth my_mastodon

This command will authenticate your Mastodon account and provide SiloRider with the permission to post to your timeline. The authorization tokens are stored in a cache file that defaults to silorider.db, next to the configuration file. Later, this cache will also contain the list of entries already posted to each silo.

Once authenticated, you can run:

silorider populate

This will populate the cache with the existing entries, since you probably don’t want the first run of SiloRider to cross-post your last dozen or so entries in one go.

Later, when you post something new, you can then run:

silorider process

This will pick up the new entries and post them to Mastodon. You can run this command again regularly… if there’s something new, SiloRider will cross-post it to the configured silos. If not, it will just exit.
