Playground zip

With the Playground format, the export is a .zip ready for WordPress Playground: a blueprint bundle that installs the themes and plugins you chose and imports the content.

Run it

npx @wp-playground/cli@latest server --blueprint=./site.zip

Or open its link on playground.wordpress.net (new screen: the Open in Playground action in Copies; classic screen: Keep a copy to open by link). The copy is served with the CORS headers Playground needs.

Even from a local server. Playground runs in your browser, so a copy made on WordPress Studio or any localhost site opens on playground.wordpress.net without uploading it anywhere — the browser fetches it from your machine (the link works on your computer only).

Themes and plugins

Any installed theme or plugin can go in. The ones from the WordPress.org directory aren’t copied: the blueprint installs them from the directory, in the version this site has (woocommerce.11.2.1.zip). The others — premium, custom, in-house — are zipped from the site into the bundle, and Playground installs them from there. WordPress’s own update check says which ones are from the directory.

Use it responsibly. Premium and custom themes and plugins are copied into the file. Share a Playground .zip only where their licenses allow — keep the ones with paid licenses to yourself or your team.

Inside

blueprint.json
<site>.WordPress.<date>.xml        the plain WXR (content inside, not in post_content/)
uploads/…                          media files, when Media files is on
post_content/…                     content files, when Content as .html files is on
themes/<stylesheet>.zip            each theme chosen that isn't in the directory (a child brings its parent)
plugins/<slug>.zip                 each plugin chosen that isn't in the directory

What the blueprint does

1. Installs the themes (parents first) — from the directory or from the bundle — and activates the active one, if chosen, else the first.
2. Installs and activates the plugins, the same way.
3. Writes the media and content files and two temporary must-use plugins: one answers the importer’s media downloads from the files and puts each .html back into its post (wp_import_post_data_raw); the other sets the options when the import ends, with IDs mapped.
4. Runs importWxr (Playground installs the WordPress Importer itself).
5. Removes the temporary plugins and files.

The eizport_playground_blueprint filter changes the blueprint before it is written.
