WordPress Playground Table Focus

There are many ways to contribute to WordPress Playground depending on your background and comfort level.

  • Testing and feedback: Help test Playground features, including PR Previews V3, the new SQLite integration, and tools powered by Playground such as My WordPress.
  • WordPress Studio: Help test the new version of WordPress Studio on Linux and provide feedback on the local development experience.
  • Blueprints: Help plugin developers create their own Blueprints and enable the Live Preview button for their plugins.
  • Documentation: Improve existing docs, suggest new guides, or help make Playground easier to understand for new users and contributors.
  • Translations: Playground documentation is currently available in several languages, and translation contributions are always welcome.
  • Good first issues: New contributors can start with issues labeled Good First Issue.
  • Design, marketing, and product feedback: You don’t need to write code to contribute. Designers, marketers, writers, educators, and site builders can help review the UI, improve onboarding, suggest new features, and identify opportunities for clearer communication.

A good quote from Jonathan Bossenger(@psykro):

Remember: it’s “Contributor Day,” not “Contribution Day.” The goal is to find meaningful ways to contribute and help move the project forward. Some work may continue after the event, and that’s expected. Open source is iterative.

If you’re not sure where to start, talk to a table lead in person or ask in the #playground Slack channel.

What WordPress Playground Is Building

WordPress Playground lets you run WordPress directly in the browser, without setting up a traditional local server. It helps people test WordPress, try plugins and themes, create demos, review pull requests, and build new contribution workflows with less setup friction.

Some of the key areas contributors may work with include:

  • Playground web instance: The public browser-based Playground available at playground.wordpress.net.
  • Blueprints: JSON files that define how a Playground instance should be configured, including plugins, themes, content, settings, and setup steps.
  • PR Previews: Playground-powered previews that make it easier to test WordPress pull requests directly in the browser.
  • SQLite integration: Ongoing work around improving WordPress support for SQLite-powered environments.
  • Playground CLI: A Node.js package that allows contributors and developers to run WordPress locally without Docker, MySQL, or Apache.
  • WordPress Studio integration: Local development workflows powered by Playground, including ongoing testing for Linux support.
  • Documentation and translations: Contributor-friendly docs that help more people understand and use Playground across different languages and workflows.

You can learn more in the Playground documentation and the dedicated Contributor Day page.

Prepare at Home

To make the most of Contributor Day, please prepare before arriving. Wi-Fi at large events can be unreliable, and many contributors may be cloning repositories or installing dependencies simultaneously.

For most Playground contribution tasks, you will need:

  • A laptop
  • A GitHub account
  • A WordPress.org account
  • Git installed
  • Node.js and npm are installed
  • A local copy of the Playground repository

We recommend cloning the Playground repository before Contributor Day:

github.com/wordpress/playground

Docker and Composer are not required for most Playground Contributor Day tasks.

If you want to work with plugin demos or Live Preview support, it may also help to review the Playground Step Library before the event.

Helpful Resources

Looking Ahead

At WCEU Contributor Day, we’ll focus on testing new features, improving documentation, supporting plugin developers with Blueprints and Live Preview, reviewing the user experience, and helping new contributors find their first meaningful contribution.

Contributors whose pull requests are merged may also be eligible for the WordPress Playground contributor badge on their WordPress.org profile. If you’re interested in Playground but unsure where to begin, join us at the Playground table or ask in the #playground Slack channel.
