## Introduction
WordPress is the world's most popular content management system, powering an estimated 40% of all websites. Originally a blogging tool, it has grown into a flexible platform for business sites, e-commerce stores, portfolios, forums, and nearly any type of web presence imaginable.

## What WordPress Does
- Publishes posts and pages with a rich block editor (Gutenberg) for visual content creation
- Manages media libraries with image editing, gallery creation, and video embeds
- Supports thousands of themes for design customization without coding
- Extends functionality through a plugin ecosystem of over 60,000 free plugins
- Provides user role management from subscriber to administrator with granular capabilities

## Architecture Overview
WordPress is a PHP application running on a MySQL or MariaDB database with an Apache or Nginx web server. The core follows a hook-and-filter architecture where plugins and themes attach to action hooks and modify data through filters. The REST API exposes content endpoints for headless use cases. WP-Cron handles scheduled tasks, and object caching can be offloaded to Redis or Memcached.

## Self-Hosting & Configuration
- Requires PHP 7.4+ (8.2 recommended), MySQL 5.7+ or MariaDB 10.4+, and a web server
- Configure database credentials and security salts in wp-config.php
- Deploy via Docker, traditional LAMP/LEMP stack, or one-click installers from most hosting providers
- Use WP-CLI for command-line management of installations, plugins, themes, and databases
- Harden security with file permission lockdowns, two-factor authentication plugins, and regular updates

## Key Features
- Block editor (Gutenberg) for drag-and-drop visual page building
- Full-site editing with block themes for complete design control
- WooCommerce integration turns any site into a full e-commerce store
- Multisite mode for managing networks of sites from a single installation
- Multilingual support via plugins like WPML or Polylang

## Comparison with Similar Tools
- **Ghost** — Modern Node.js publishing platform focused on newsletters; less flexible for non-blog use cases
- **Drupal** — Enterprise PHP CMS with stronger content modeling; steeper learning curve
- **Strapi** — Headless Node.js CMS for API-driven content; no built-in frontend rendering
- **Joomla** — PHP CMS with built-in ACL and multilingual support; smaller ecosystem than WordPress
- **Hugo / Astro** — Static site generators; faster performance but no built-in admin UI or dynamic content management

## FAQ
**Q: Is WordPress really free?**
A: Yes. WordPress core is GPL-licensed and free to use, modify, and distribute. Costs come from hosting, premium themes, and premium plugins.

**Q: How do I keep WordPress secure?**
A: Keep core, themes, and plugins updated, use strong passwords with two-factor auth, limit login attempts, and use a web application firewall.

**Q: Can WordPress handle high-traffic sites?**
A: Yes. With proper caching (Redis, Varnish, CDN), optimized hosting, and database tuning, WordPress powers sites serving millions of monthly visitors.

**Q: Is WordPress suitable for headless or decoupled architectures?**
A: Yes. The built-in REST API and community GraphQL plugins (WPGraphQL) make WordPress a capable headless CMS backend.
