Can I Install My Own WordPress Plugins and Themes?

Yes. Every WordPress sandbox includes full WordPress administrator access, allowing you to install your own plugins and themes just as you would on a regular WordPress website.

You are free to upload premium themes, install plugins from the WordPress repository, or upload custom plugins and themes manually. This makes WP Sandboxes suitable for testing new functionality, evaluating premium software, learning WordPress, and developing websites without affecting a live environment.

Our preconfigured sandbox templates provide a starting point, but you are free to customize your sandbox as needed.
