It’s not stable yet but the concept is intriguing, as it opens up a world of potential use cases. image source: demo from wordpress-wasm repo The project is available on GitHub and Zielinski briefly explained how it works: PHP is compiled to WASM with Emscripten WordPress is packaged into a data bundle A service worker traps HTTP requests and re-routes them to WordPress The project uses the wp-db-sqlite plugin to run WordPress with SQLite, as WASM doesn’t support MySQL. Zielinski detailed some possible applications for running WordPress in the browser, which he said could “transform learning, contributing, and using WordPress:”  making WordPress handbook code samples runeditable (early preview) providing an in-browser IDE to assist new contributors without having without having to set up a local development environment (early preview) creating an in-browser IDE for testing code on different WordPress, PHP, and Gutenberg versions scaling WordPress up by spinning up many tiny self-contained WASM instances directly on…
