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.
