QUICK ANSWER
What are the best WordPress developer resources?
The best WordPress developer resources are the official WordPress Developer Resources site (developer.wordpress.org) with its code reference and handbooks for themes, plugins, blocks and the REST API, plus WooCommerce developer docs, WordPress coding standards, Learn WordPress courses and local tools such as WP-CLI.
What official WordPress documentation should developers know?
The Code Reference for functions and hooks, the Theme Handbook, Plugin Handbook, Block Editor Handbook, REST API Handbook and Common APIs Handbook. Start there before relying on third-party tutorials.
What do the numbers say about WordPress in 2026?
WordPress is used by 39.7% of all websites and 58.5% of websites whose content management system is known, according to W3Techs (October 2026). WooCommerce runs on 19.8% of WordPress sites. Google's Core Web Vitals define a good experience as Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint of 200 milliseconds or less and Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile of page loads (web.dev). Toffyjar prices WordPress projects at about $199 per page, so a 10-page build is roughly $1,990, and dedicated WordPress developers cost $10 an hour, or $18 an hour for senior developers. In short, WordPress is the default platform for business websites, and speed is a measurable requirement rather than a preference.
Which tools do WordPress developers use?
A small toolkit covers most daily work.

|---|---|
| WP-CLI | Command-line management |

| Query Monitor | Debugging queries and hooks |
| Git | Version control |
