WordPress
WordPress is the world’s most popular content management system, powering a large share of websites with themes, plugins, and a PHP/MySQL stack.
WordPress is the most widely used cms in the world, powering a substantial share of all websites. It is open-source software written in php and backed by a mysql database.
Why it dominates
- Themes control appearance; plugins add functionality without coding.
- A vast ecosystem and gentle learning curve.
- Suits everything from blogs to large e-commerce stores.
Performance and security notes
- Dynamic pages benefit greatly from
caching(page cache plus object cache) to improvettfb. - Because of its popularity, WordPress is a frequent attack target — keeping core, themes, and plugins updated, and using a
waf, is essential.
Why it matters for hosting
Many hosts offer managed WordPress plans (a form of managed-hosting) that bundle tuned php, server-side caching (often via litespeed or nginx), automatic updates, and security. Matching your host to WordPress's stack is the simplest route to a fast, secure site.
