Web development — Subnetix, Cornwall

SERVICES / WEB DEVELOPMENT

Websites built like software. Because they are.

Plenty of agencies will sell you a heavy WordPress theme, stack plugins on it until it works, and disappear. We write the code ourselves, set a performance budget before we start, and stand behind it after launch.

Rescue & rebuilds

Inherited a slow, fragile site nobody dares touch? We audit it, tell you plainly whether it's worth saving, and either fix it or rebuild it properly.

One build. Every screen.

Layouts reflow rather than shrink — designed mobile-first, then tested at every width in between. Hover either device to scroll it.

Why the engineering matters

A slow site costs you twice: visitors leave before it loads, and search engines rank you below competitors who load faster. A site nobody can maintain costs you a third time, every time you need a change.

So we set a performance budget before design starts, write code a stranger could maintain, and document what we hand over. It's not glamorous. It's the job.

Show us the site you've got.

We'll tell you what's slowing it down and what a rebuild would cost — before you commit to anything.
