Top 5 web developers in Cardiff (2026)

A web designer makes a site look right. A web developer makes it work: fast, secure, easy to update and found on Google. Here’s who to talk to in Cardiff.

November 2026 · 5 min read

The right developer depends on the job. A small business that needs a quick, well-built site wants something very different from an organisation planning a web application or a site with dozens of editors.

These five Cardiff developers cover that range, from a freelancer to a full agency.

A note on this list: this website is run by Nathan Constance, who also runs NC Digital, the developer ranked first. The others are listed on their own merits, using their public Google profiles and the services they advertise.

What we looked at

  • Speed and build quality
  • Proven results for real clients
  • Reputation and Google reviews
  • The kind of projects they handle well
  • Clear pricing and support after launch
  • Experience with Cardiff businesses

    NC Digital

    Serving Cardiff and the Vale

    NC Digital is run by Nathan Constance, a web developer who designs and builds every site himself, from the first plan to launch and the updates that follow.

    Builds are lean and mobile-first, so pages load quickly on a phone signal, and each one is set up for Google from the start: clean headings, fast images, schema markup and proper internal links. Most sites are built on WordPress with Bricks Builder, which keeps the code tidy and lets owners edit their own pages.

    Pricing is published: a custom website from £199 paid once, or a managed website from £20 a month with hosting and changes included. NC Digital holds a 5.0 rating from 17 Google reviews, and its case studies show what the builds go on to achieve.

Choosing the right developer

Ask to see live sites they’ve built and test them on your phone. Check how fast they load, ask who hosts and maintains them, and ask what happens if something breaks. A good developer will answer all of that plainly.

For most small businesses, a well-built WordPress site with local SEO in place is the best value. Our guide to what a website costs in Cardiff explains what you should expect to pay, and our pick of the top web designers in Cardiff covers the design side.

For a fast, properly built website at a fair price, NC Digital is our top pick for web development in Cardiff in 2026.
