Why we build every website on Next.js, in plain English.

What 'custom-coded' actually means underneath: the framework behind our sub-second sites, why it matters for Google, and the honest trade-offs.

Next.js is the framework we build every website on, and this page exists because business owners increasingly ask a sensible question: when a developer says "custom-coded", what is actually underneath, and does the choice matter to someone who just wants more enquiries? The short answer: Next.js is the technology behind some of the world's busiest websites, it is why our sites load in under a second, and the honest trade-off is that it is a developer's tool rather than a tinkerer's one. Here is what that means in plain English.

What Next.js is, in plain terms

Next.js is a framework, a set of professional building tools, used to construct websites from code rather than assemble them from themes. It is open source, maintained by some of the best-funded engineering in the industry, and used by household-name companies for exactly the kind of fast, search-friendly marketing sites small businesses also need. Choosing it is not exotic; it is the boring, robust choice a builder makes about materials before the customer ever sees a wall.

The part that matters to you is what it produces: pages that are prepared in advance rather than assembled while your customer waits. When someone taps your site from a Google result on a phone in a car park, the page arrives finished. That is the single biggest practical difference from the template stacks most small-business sites sit on.

Why pre-built pages change your Google position

Google measures how real visitors experience your site through Core Web Vitals, and speed is the heart of it. A WordPress site assembles each page from a database, a theme and a stack of plugins on every visit; caching plugins exist precisely because that assembly is slow. A Next.js site like ours skips the problem: the pages are built once, at publish time, and served instantly from fast infrastructure around the world.

This is not theoretical for us. This very website, along with every client site we build, runs on Next.js, and sub-second loading is a number we publish and are held to. The same speed also does quiet commercial work: fewer visitors give up waiting, and our guide to Core Web Vitals covers how Google folds that experience into rankings.

No plugin stack, and why that is a security feature

Most hacked small-business websites are WordPress sites with an out-of-date plugin, not because WordPress is bad, but because a typical install runs dozens of plugins with independent update schedules, and each one is a door. A custom-coded Next.js site has no plugin stack at all: the features your site needs are written into it, and the attack surface where most breaches start simply is not there. Security stops being weekly homework and becomes a property of the build, which is exactly the structural argument made in our website security guide.

The honest trade-offs

A balanced page has to say this plainly: Next.js is not the right answer for every business. You cannot log into a dashboard and rearrange your homepage the way a Wix or WordPress owner can; content changes go through your developer or through an editing setup wired in for you. If your business publishes daily and wants full hands-on control of layout, a traditional CMS may genuinely fit better. And a Next.js site is only as good as the developer behind it, because the framework hands power to whoever writes the code, for better or worse.

Our answer to the editing question is the maintenance plan: content changes are included, so "email Jack the new prices" replaces "log in and fight the page builder", which most trade and service businesses quietly prefer. But it is a preference, and you should choose it knowingly.

Does building on Next.js cost more?

With us, no, and it is worth understanding why the market sometimes suggests otherwise. Agencies often price custom frameworks as a premium because their processes around them are heavy. Our position is the reverse: building on Next.js is cheaper to run than maintaining a plugin stack, because there are no licence fees for premium plugins, no emergency updates, and hosting for pre-built pages costs a fraction of what database-driven sites need. That saving is baked into our published prices, from £675 +VAT for a full custom build, and into the £39 +VAT monthly plan that keeps everything fast and current. The technology choice funds the price, not the other way round.

What this means when you choose a developer

You do not need to care about frameworks, but the technology a developer reaches for tells you what they sell. Ask what your site would be built on and why. "A theme we customise" is a template business, fine at template prices. "WordPress with a page builder" means plugins, updates and hosting weight, workable but with running costs measured in attention. "Custom-coded", on Next.js or its peers, means the site is being built around you, which is the method behind genuinely bespoke website design and the reason we work this way at every price tier, from £675 +VAT upward.

The framework is not the point. The enquiries are. Next.js is simply the tool that lets us promise the speed, security and search structure that produce them, and put the numbers in public where you can check us against them.

Honest pricing

Frequently asked questions.

A professional framework for building websites from code rather than themes, used by some of the world's busiest sites. Its key trick is preparing pages in advance so they load instantly, instead of assembling them from a database and plugins on every visit.

The framework itself is not a ranking factor, but what it produces is: pre-built pages load faster, pass Core Web Vitals more easily, and carry none of the template weight that slows typical WordPress installs. The structure still has to be built well by whoever codes it.

Not through a drag-and-drop dashboard by default, and that is the honest trade-off. Our maintenance plan includes content changes, so updates become an email rather than a login, and an editing setup can be wired in when a business genuinely needs hands-on control.

Not with us. No plugin licences, no emergency plugin updates and cheaper hosting for pre-built pages mean the running costs are lower than a typical WordPress stack, and our build prices are published from £675 +VAT.
