WordPress Plugin Development Services
If an existing plugin doesn’t cover your business logic at 100%, stacking two or three more on top of it usually costs more — in conflicts, page weight, and support time — than building the one plugin that does the job cleanly. We build custom WordPress plugins the same way we build our own: domain model first, WordPress integration second.
What we build
- Custom Gutenberg blocks — dynamic and static, with proper
block.json, attributes, and editor/front-end parity — not a shortcode wrapped in a block for appearances. - Full plugins for specific business logic — custom post types, taxonomies, admin screens, settings pages, capabilities and roles.
- Third-party integrations — REST APIs, OAuth, webhooks, CRMs, booking and calendar systems, payment providers.
- Plugin rescue and refactoring — inherited a plugin nobody on the team wants to touch anymore? We read the code and the git history before we read the changelog.
Proof, not a pitch deck
10 plugins published on WordPress.org today, live and maintained — including 4WP Smart Link, 4WP FAQ, 4WP Drive, 4WP Notifications, and 4WP Weather. All of them run on 4WP Bundle, the shared architecture foundation we maintain in the open on GitHub. You can read the code before you hire us.
How we work
- Understand the domain before writing a line of PHP. Business logic gets modeled first; the WordPress integration (hooks, CPTs, REST) comes second — the same DDD approach documented in our Methodologies section.
- Design the smallest correct architecture, not the most flexible one. Over-engineering costs you as much as under-engineering.
- Ship, document, and stay reachable for the maintenance that follows — see our Maintenance services if you want that built in from day one.
Who this is for
Agencies and companies for whom “just add another plugin” has stopped working, and site owners who need one specific feature that doesn’t exist yet in any plugin on the market. This is custom WordPress development in the literal sense — not a page builder with your logo on it.
Get started
Tell us what the plugin needs to do, not just what it needs to look like. We’ll scope it honestly — including telling you when a smaller fix or an existing 4WP plugin already covers it.
