For WordPress Developers

4WP.dev is a knowledge base built on production code — not abstract tutorials. Study open-source plugins, Gutenberg block patterns, Block Editor APIs, and architecture decisions you can apply to client work immediately.

What you get from 4WP.dev

  • Architecture case studies — real plugins as reference implementations (blocks, REST, settings, SEO, MCP abilities)
  • Gutenberg block development — custom blocks, Interactivity API, Query Loop extensions, FSE patterns
  • Modern WordPress tooling — Composer, Abilities API, MCP Adapter, WP-CLI workflows
  • SOLID & design patterns — documented approaches in the Development section
  • Source you can fork — every major plugin has a public GitHub repository

How to use this hub

Pick a plugin close to your problem, read its architecture notes, clone the repo, and adapt the patterns. Follow the Development track for deeper guides on hooks, blocks, and project structure.
