About this service

When no existing plugin does what you need, or the one you use is bloated and insecure, a small custom plugin is often the cleanest answer. We build it to WordPress coding standards, with proper security checks, settings pages and translation support, so it survives core updates and other developers can maintain it.

A small plugin instead of a big one

Many WordPress sites install a large plugin to use one small feature. The plugin loads code on every page, adds database tables, shows upsell notices and creates security risk for features nobody uses.

A small custom plugin that does exactly one job is often faster, safer and cheaper to maintain. We build it using WordPress hooks and standards, so it works with core updates rather than fighting them.

Security is not optional

Plugins are one of the most common entry points for attacks on WordPress sites. Missing permission checks, unvalidated inputs and unsafe database queries let attackers change settings, inject code or access data.

Every form and action in our plugins includes nonce verification, capability checks, input sanitisation and output escaping. Database queries use prepared statements. These practices are part of WordPress coding standards and part of every plugin we deliver.

Compatibility matters too. We test on staging with your theme and other plugins, and avoid editing commercial plugins directly. Extensions use hooks, so updates do not erase custom work.

  • Nonce and capability checks on every action
  • Sanitised inputs and escaped outputs
  • Prepared database queries
  • Hooks instead of edits to other plugins

Questions

Can you fix an existing plugin instead?

Yes. If it is a commercial plugin we usually extend it through hooks rather than editing its code, so updates do not wipe the changes.

Can the plugin go on WordPress.org?

It can be prepared for submission to the plugin directory. Approval is decided by the WordPress review team.

Who owns the code?

You do, under a licence compatible with WordPress.
