Read the full description

Since ~40% of all websites supposedly still run on WordPress (WP), I thought it might be useful to run it faster. BookPress is about 50% faster than a performance-tuned WP setup with Elementor and WooCommerce.Every time I used WordPress in the past, I got frustrated how slow it was, even with just a few plugins. So I wrote an light-weight C/C++ core and an embeddable PHP engine to run plugins and themes, with most of the WP API surface covered.Try the live demo, including wp-admin!The embeddable PHP runtime that covers most of Zend PHP's features runs 2x slower than Zend, but BookPress is still faster than a performance-tuned WP instance with OPCache, page cache and object caches.BookPress runs alongside a traditional WP installation on Linux arm64 and x86_64.Looking forward to what you all think.

Could you build this?

No Reimplementing WordPress core natively in C/C++ and serving existing PHP sites with plugins requires near-complete compatibility with PHP semantics and the WordPress API surface. That is a massive, expert-level systems project beyond what vibe coding can deliver.

What it would actually take: A real version would need a compatible implementation of the WordPress core API, the hook and filter system, the database schema and query behavior, and either an embedded PHP runtime or a compatibility layer for plugins. It requires experienced compiler and runtime engineers, extensive compatibility testing against the plugin ecosystem, and years of effort to match WordPress's behavior.
