Web application custom development UK

19th October 2026

Script Monkey makes websites like this. We can include agents, databases and any other technology you wish.

We love custom web application development. We can register domains for you, host your site on our UK dedicated server, code your site, add a database, extend your office systems online and more. If you can describe what you want to achieve, we can help you achieve it.

We have engineered custom e-commerce sites in ASPX/C# from scratch with complete stock control for businesses from the music industry to telecoms. We don't do graphic design, but if you give us your graphic styles, we can shape a web presence for you to be the envy of the competition. We made this site entirely without a graphic designer to give you an idea about the possible end result we can achieve.

More than a website

A brochure website tells people who you are. A web application does something for them. The difference is the logic and data behind the page: a customer checking the status of an order, a site manager logging deliveries from a phone, or an engineer pulling up the latest drawings in a browser rather than hunting through a shared drive.

Because a web application runs in the browser, there is nothing to install and nothing to update on each machine. Staff can use it from the office, from home or from site, on a laptop, tablet or phone, and everyone always sees the latest version.

What we build for the web

  • Business websites, fast, responsive and built to be found.
  • E-commerce sites, with stock control, orders and payments tied together.
  • Online portals, giving staff, clients or suppliers secure access to the information they need.
  • Office systems online, taking an existing database or spreadsheet process and making it available anywhere.
  • Scrapers and data feeds, gathering information from around the web automatically.
  • Trading bots, for those who want their strategies running around the clock.
  • Interactive 3D and graphics, using WebGL and Three.js to bring data and designs to life.

Hosting and support under one roof

Plenty of web projects stall because the domain is with one company, the hosting with another, and the developer somewhere else again. We can handle the lot, from registering your domain to hosting your site on our UK dedicated server, so there is one point of contact when you want a change made or have a question answered.

Built to be seen

A beautiful site is wasted if nobody can find it. We write clean, standards based code that loads quickly, works on every screen size and gives search engines a clear picture of what each page is about. That foundation makes everything else, from marketing to search rankings, easier.

Questions we often hear

Can you put our existing office system online?
Often, yes. Many of the systems we build start life as a desktop database or a set of spreadsheets. We can move the data to a server and build a secure web front end, so your team keeps the process they know but gains access from anywhere.

We already have a website. Can you add to it?
Certainly. Whether you need an online shop, a customer login area or a connection to your office database, we can extend what you have rather than starting again.

Do we need a graphic designer?
Not necessarily. If you have brand colours, fonts and a logo, we can build a polished site around them. If you want a full visual identity created, we are happy to work alongside your designer.

See it in action

For a taste of what the browser can do, explore our interactive Mandelbrot and Julia set explorer or our experiment in 3D document management. And if your web application needs serious data behind it, take a look at our bespoke database development service.

Much of our online work is not for the public internet, being business solutions for commercial clients, but below are examples of our work, including a site for an astrophotographer and the Experience Facades site we built for facade expert Steve Daniels. And of course, we made our own site that you are looking at now. We will post more sites here in the coming months.
