Plugins directory
The Buildkite plugins directory (also accessible from the main Buildkite website), allows you to discover and find all plugins maintained by Buildkite, as well as those from third-party developers.
Once you have created your own plugin, you can also add it to the plugins directory.
buildkite.com/resources/plugins
Plugins supported by the Buildkite team display the Buildkite logo in the directory, and can be found in the Buildkite Plugins GitHub organization.
For the instructions on writing and adding your plugin to the Buildkite plugins directory, see Writing plugins.
