WordPress Playground: WordPress in the Browser

The rapid deployment of WordPress has always been its advantage, especially since its famous "five-minute installation". Just upload a small number of files and configure a small number of settings to start.

The friction of uploading files has been greatly reduced thanks to the numerous "one-click" installation options provided by many hosts (including DigitalOcean and Cloudways).

Some companies are trying to simplify this process further, using WordPress's multi-site feature to launch one-time instances for testing and demonstration. WordPress Sandbox and WP Sandbox fall into this category. Since instances run on the same installation, this adds latency to the entire network, scalability can be a problem. I've worked on a headless WordPress project that does this for users in the background and I remember that as the number of sites on the network increases, it takes a very long wait for users to create new accounts.

Now, we are welcome to WordPress Playground. It runs completely in the browser, which is simply incredible for me as a long-time WordPress user. If you have trouble understanding how it works like me, the link to the overview explains this well:

PHP runs as WebAssembly binary

• Replace MySQL with SQLite through WordPress plugin
• Implementing Web Server using Service Worker API

It's so cool. The move to SQLite is particularly interesting because it can bring huge performance gains to many sites that may not require the full functionality of WordPress – as Chris recently described in a different context. In fact, this work has been done in an experimental WordPress performance plugin.

Evolution toward lightweight, frictionless WordPress is an interesting area. I think a considerable portion of existing WordPress sites can benefit from streamlined CMS. This demonstration shows what the introductory experience of this approach might look like.
