Custom Development

Stop searching for
"a plugin for that".

Off-the-shelf plugins are bloated, slow, and insecure. We build lean, custom WordPress plugins that do exactly what you need—and nothing else.

The Bloat

"Plugin Soup" is killing your site.

You install a 10MB plugin just to add a single button. It loads 5 CSS files, 3 JS files, and makes 20 database queries on every page load.

The Vulnerability Risk

98% of WordPress vulnerabilities come from third-party plugins. Custom code means a smaller attack surface.

What we build

Custom Post Types
Real Estate listings, Team Members, Event Calendars.
API Integrations
Syncing WooCommerce orders to your ERP system.

Bespoke drag-and-drop components for your editors.
plugin-performance.php
// ❌ Generic Plugin (Slow)
add_action('init', 'load_everything');
function load_everything() {
// Loads on every single page
wp_enqueue_script('heavy-library.js');
}
// ✅ Montandon Custom Plugin (Fast)
add_action('wp_enqueue_scripts', function() {
if (!is_page('contact')) return;
// Only loads where needed
wp_enqueue_script('form-logic.js');
});
Performance

Code that respects your server.

We write object-oriented, standards-compliant PHP. We use transients to cache expensive database queries and ensure we only load assets on the pages that need them.

  • No Vendor Lock-in

    We follow WordPress Coding Standards. Any developer can maintain our code.

  • Maintenance Free

    Unlike marketplace plugins, our code doesn't break when WordPress updates, because we don't use hacky workarounds.
