The WPCTO WordPress tech stack: Tools we trust for scalable, secure, high-performance websites
A breakdown of our proven WordPress development environment, ideal for general-purpose sites, eCommerce and small to mid-level traffic projects.
Why a solid WordPress stack matters
At WPCTO, we don’t just fix or support WordPress websites, we build and optimise them with the future in mind. A solid, secure, and scalable tech stack is the difference between a website that simply exists and one that performs under pressure.
Our WordPress stack is tailored for:
General-purpose content sites
Charities, membership platforms and donation platforms
Websites needing robust security and integrations
Here’s what we use, every tool on this list is battle-tested, fast, secure, and ideal for WordPress at scale.
🧠 Content management & code
WordPress
The world’s most popular CMS — flexible, open-source, and endlessly extensible. We work exclusively with WordPress because it gives our clients full ownership and adaptability.
Elementor
Our preferred visual builder — perfect for clients who want to edit content themselves without breaking layout integrity. Highly extendable, well-supported, and plays nicely with custom fields.
HTML5, JavaScript, CSS3
Core web standards for front-end delivery. Our sites are written semantically and cleanly, to ensure performance, accessibility, and SEO-readiness.
PHP
The backbone of WordPress. We use current, supported PHP versions and code with stability and performance in mind.
W3C Standards
All code adheres to W3C validation for HTML and CSS — it’s about long-term compatibility, cleaner rendering, and better performance.
💳 E-commerce & payments
WooCommerce
Our go-to eCommerce platform for WordPress. Great for shops, donations, subscriptions, and product catalogues. Fully customisable and scalable.
Stripe
Secure, modern payment gateway for cards, Apple Pay, Google Pay and more. Our integration supports both single payments and recurring billing.
🛡️ Security & transactional email
