Preview WordPress Core Pull Requests Directly in Playground
Contributors can now boot a Pull Request in WordPress Playground from the GitHub UI. The loop from patch to clickable site just got shorter, which matters if you review with your eyes as much as your diffs.

Reviewing WordPress core used to mean spinning up a local stack or trusting screenshots. A new Playground integration lets you open a pull request in a browser-based WordPress instance with the patch already applied.
For design-adjacent changes — editor chrome, admin notices, twenty-twenty-whatever tweaks — this is the difference between commenting and actually clicking. It also lowers the cost of drive-by reviews from people who will never clone meta.
The workflow is still young. Plugins that need a server beyond what Playground emulates will not magically work. PHP unit tests still live in CI. But for “does this button look right,” the barrier just dropped.
If you have been waiting for a reason to try contribution without a local environment, this is that reason. Open the PR, press preview, and tell the author what you saw.
