Mattermost plugins are isolated pieces of code written in Go and/or React. They're separate from the main repositories and are used to extend the functionality of the Mattermost server and webapp.

- The Go portions run directly on the Mattermost server, and are managed by the server at runtime.
- The React portions run in each user's browser, allowing developers to modify the user interface in [several ways](/developers/integrate/plugins/components/webapp/best-practices).

The plugin Help Wanted tickets are located in each plugin's respective GitHub repository. In order to browse all of the open tickets, see the plugin [Help Wanted tickets](https://mattermost.com/pl/help-wanted-plugins/) page with links to specific plugin repositories, as well as queries for Help Wanted tickets in all repositories.

The plugin [developer setup](/developers/integrate/plugins/developer-setup) and [developer workflow](/developers/integrate/plugins/developer-workflow) pages are useful to learn about the plugin development environment. You can find more information about plugins in general [here](/developers/integrate/plugins).


<Note title="Note">
The `make` commands listed in the [developer workflow](/developers/integrate/plugins/developer-workflow#common-make-commands-for-working-with-plugins) page (specifically `make test` and `make check-style`) should be used locally to run certain tests before submitting a PR. This makes the PR review process much more streamlined overall.
