# 2.10. Plugin Infrastructure in Buildbot

Added in version 0.8.11.

Plugin infrastructure in Buildbot allows easy use of components that are not part of the core. It also allows unified access to components that are included in the core.

The following snippet

    from buildbot.plugins import kind

    ... kind.ComponentClass ...

allows to use a component of kind `kind`. Available `kind`s are:

`worker`

  workers, described in Workers

`changes`

  change source, described in Change Sources and Changes

`schedulers`

  schedulers, described in Schedulers

`steps`

  build steps, described in Build Steps

`reporters`

  reporters (or reporter targets), described in Reporters

`util`

  utility classes. For example, BuilderConfig, Build Factories, ChangeFilter and Locks are accessible through `util`.

Web interface plugins are not used directly: as described in web server configuration section, they are listed in the corresponding section of the web server configuration dictionary.

Note

If you are not very familiar with Python and you need to use different kinds of components, start your `master.cfg` file with:

    from buildbot.plugins import *

As a result, all listed above components will be available for use. This is what sample `master.cfg` file uses.

## 2.10.1. Finding Plugins

Buildbot maintains a list of plugins at https://github.com/buildbot/buildbot/wiki/PluginList.

## 2.10.2. Developing Plugins

Distribute a Buildbot Plug-In contains all necessary information for you to develop new plugins. Please edit https://github.com/buildbot/buildbot/wiki/PluginList to add a link to your plugin!

## 2.10.3. Plugins of note

Plugins were introduced in Buildbot-0.8.11, so as of this writing, only components that are bundled with Buildbot are available as plugins.
