Plugin and extension development

Plugin development covers extensions that must live inside someone else’s runtime—WordPress hooks, commerce app modules, or CMS integrations—rather than standalone services. PunkSolid writes them in Cursor with the same review habits we use when exiting WordPress entirely.

When plugins still make sense

Plugins are appropriate when you are not ready to replatform, when marketplace distribution matters, or when a short extension bridges two systems during a longer migration. If the end state is a static or edge-hosted site, compare WordPress to Astro or Next.js and website migration so you do not invest in PHP code you plan to retire.

For bespoke automation outside the CMS, see custom software development.

Security and quality

Platform plugins fail loudly when permissions, sanitization, or update paths are wrong. Human review covers those paths on every merge. Agents help with boilerplate blocks and admin screens; engineers own activation hooks and data migrations.

Our methodology document explains automated link and type checks on the wider properties we ship. Plugin repos adopt the checks that fit the ecosystem—PHPUnit, PHPCS, or static analysis where configured.

Migration context

Eight healthcare provider sites—1,000–6,000 pages each—depended on Elementor, ACF, and WP All Import before rebuilds in Cursor. The healthcare WordPress rebuilds case study explains how tracking, forms, and imports were recreated without those plugins. Plugin development engagements sometimes build the last mile of that transition: an importer that runs until cutover, or a block that stabilizes editorial workflow.

We have rebuilt nine sites across client and network work with full code handoff. Vendor trademarks such as WordPress are used only to describe platforms we integrate with.

Handoff

You receive source, install documentation, and optional 1:1 Cursor coaching for the team publishing updates, with code ownership of the plugin source at handoff. We do not quote fixed prices on this page.

Related work

Legacy application modernization helps when the plugin is one piece of a larger aging stack. AI code review adds a focused security and hygiene pass on agent-generated plugin code.

Use contact when you can share the platform version, conflict plugins, and release window.

Update and compatibility strategy

Plugins need a plan for WordPress core bumps, PHP version lifts, and conflicting page builders. Discovery lists supported versions, whether auto-updates are allowed, and how rollbacks work on production. We document uninstall behavior so deactivating the plugin does not orphan patient-facing shortcodes or commerce SKUs.

Relationship to full replatforms

When you intend to exit WordPress within two release cycles, we say so in the roadmap. It may be cheaper to fund a migration through website migration than to invest heavily in new PHP when Astro or Next.js is the end state. Plugin work still makes sense for interim importers, editorial blocks, or compliance forms that must ship before cutover.

Proof and confidentiality

Large plugin-heavy stacks appear in the healthcare WordPress rebuilds story: Elementor, ACF, and WP All Import were replaced by typed content and imports in Cursor. We cite nine sites rebuilt with full handoff; client URLs and lead metrics remain confidential.

Release engineering

Some clients distribute via private git; others use marketplace zips. We match your channel with signing, changelog, and semantic version notes. Staging environments that mirror PHP versions on production reduce surprise fatal errors on activation.

Agency partners

If you are an agency delivering for a healthcare or other regulated end client, expect longer review on forms and tracking hooks—patterns we document on migrations rather than invent per project. Share brand guidelines and consent copy early so plugin admin screens do not block launch.

Deactivate paths deserve the same attention as activation: orphaned options in the database slow migrations later. We document cleanup steps when a plugin is retired in favor of code-first replacements from custom software development.

Multisite WordPress networks and role matrices need explicit test plans before rollout. We validate each site ID that will activate the plugin, not only the developer’s local single-site install.

Describe your release channel on contact so we scope packaging correctly. List conflicting plugins up front to avoid surprise incompatibilities during QA. Point us to website migration when the plugin is only a bridge to a planned replatform. We align milestones with that program so you do not pay twice for the same import logic.
