How Wibble Builds High-Performance WordPress Websites
Post by lead developer Karl Proctor on how Wibble approaches custom development within WordPress to ensure improved site speed.
For a long time, editing a WordPress website meant dealing with shortcodes, bulky page builders, or templates that were easy to break and hard to understand.
Clients either felt boxed in by what they could change, or worried that one wrong click might mess up a layout completely. That’s frustrating, and it shouldn’t be that way.
Thankfully, things have changed. Block-based WordPress themes have changed how websites are built and edited. They’re more flexible, more intuitive, and much easier for clients to manage day to day. At Wibble, we’ve fully embraced this approach because it gives our clients real control over their site, without adding unnecessary complexity.
Block-based themes are central to how we build WordPress websites today.
Traditional WordPress themes rely heavily on PHP templates, widgets, and custom fields to control layouts. They’re powerful, but they often feel disconnected from the actual editing experience, and usually require a developer to make even small changes.
Block-based themes work differently.
They use the same block editor you’re already familiar with when editing pages or posts, but extend it to your entire site. That includes things like:
Everything is visual. Everything is editable. No digging through theme settings, no custom HTML, and no guessing how things fit together.
It’s a much simpler, more user-friendly way to manage a website.
We build block-based themes for one simple reason: they’re easier to use.
Here’s what that looks like in practice.

With block-based themes, what you see is what you edit.
It’s all done in a few clicks. There’s no technical barrier and no need to ask a developer for small updates. That means your team can keep content fresh, make changes quickly, and stay in control of your site.
One of the biggest concerns we hear from clients is the fear of “breaking the site”. Block-based themes massively reduce that risk.
We define your brand styles in one central place – things like colours, typography, spacing, and button styles. These rules are then applied automatically across the site. So when you create or edit content, everything stays consistent and on-brand by default. You get flexibility, but with sensible guardrails in place.
Page builders promise flexibility, but often come with downsides:
Block-based themes avoid all of that. Our themes are custom-built, lightweight, and focused on performance. We only load what’s needed. The result is:
Your site works better, without being weighed down.
As your business evolves, your website should be able to evolve too. Block-based themes make that easier because:
It’s a flexible foundation that supports growth, rather than holding it back.
We’ve chosen to build block-based WordPress themes because they strike the right balance between:
Behind the scenes, we pair this approach with a modern development stack. This includes Tailwind CSS, PostCSS, Vite, and more, to make sure every site is fast, stable, and built to last.
Clients get a website they feel confident using. We get to build with tools that keep WordPress modern and efficient.
It’s a win on both sides.
Block-based WordPress themes represent a big shift in how websites are built and managed. They give clients more freedom, more clarity, and more confidence, without the technical headaches that used to come with WordPress.
If you’re planning a new website or want to move away from restrictive page builders, a custom block-based theme could be exactly what you need.

No. We do not tie you down like that. Your site will be built with a WordPress control panel for content updates so you can change, edit, add or remove content. We can do it for you if you wish, but that’s up to you.
