The I2P network includes a plugin architecture to support both easy development and installation of new plugins.
There are now plugins available that support distributed email, blogs, IRC clients, distributed file storage, wikis, and more.
Adding Plugins To Your I2P Router
I2P Plugins can be installed by copying the plugin download URL onto the appropriate section on the Router Console Plugin Configuration Page.
Start by copying the plugin URL from the page where it is published.
Then visit the plugin configuration page, which you can find linked on the console homepage.
Paste in the URL and click the "Install Plugin" button.

Updating a Plugin
To update a plugin to the latest version, just click the update button on configclients.jsp. There is also a button to check if the plugin has a more recent version, as well as a button to check for updates for all plugins. Plugins will be checked for updates automatically when updating to a new I2P release (not including dev builds).
See the latest plugin specification
See also the sources for plugins developed by various people. Some plugins, such as snowman, were developed specifically as examples.
To create a plugin from an existing binary package you will need to get makeplugin.sh from the i2p.scripts repository in git.
Note that the router's plugin architecture does NOT currently provide any additional security isolation or sandboxing of plugins.
- Updates of a plugin with included jars (not wars) won't be recognized if the plugin was already run, as it requires class loader trickery to flush the class cache; a full router restart is required.
- The stop button may be displayed even if there is nothing to stop.
- Plugins running in a separate JVM create a
- No initial keys are present, except for those of jrandom and zzz (using the same keys as for router update), so the first key seen for a signer is automatically accepted—there is no signing key authority.
- When deleting a plugin, the directory is not always deleted, especially on Windows.
- Installing a plugin requiring Java 1.6 on a Java 1.5 machine will result in a "plugin is corrupt" message if pack200 compression of the plugin file is used.
- Theme and translation plugins are untested.
- Autostart deaktivieren funktioniert nicht immer.
