Hello from WordPress Playground!

This is Playground, a WordPress that runs client-side in your browser. It is useful for training, testing plugins and themes, and trying changes safely.

Note that you are logged-in as admin.

Temporary until saved

Save in this browser

Stores the Playground in browser storage and makes it available in the saved list on this device.

Playground name

Saving 3028 / 3751 files. Result: browser saved slug research-browser-playground.

Save to a local directory

Uses a local directory selected by the browser. The saved site remains tied to that chosen folder.

Destination

Progress result: 3751 files copied to local directory, then the tab reads Saved to local directory.

Unsaved consequence: closing the tab, refreshing the page, applying destructive settings, or importing over the current site can discard temporary work.
