Web app development in Hampshire: Booking forms, shops and a game in a wine label.
If your website has to do things, like take bookings, show live information, sell or let visitors play, we build those parts. We design and code them together in our Southampton studio, so they look and work like the rest of your site.

engineWeb app development for websites that have to do things
Beyond builds web apps in Southampton, Hampshire. A web app is the part of a website that lets people do something: book, buy, sign up or play. Most of ours sit inside websites we've designed for established brands and organisations.
We design and code them in the same studio, so your booking form or game looks like the rest of your site and works properly on every phone. You get the feature, the connection to the system behind it, and a plan in writing before we start.
What we can build into your site
- 01
Booking forms
Reservations that go straight into the booking system you already use, in a few short steps.
- 02
Menus and news your team updates
Menus that change with the season, and news or journal pages, kept up to date by your team.
- 03
Shops and sign-ups
A shop or sign-up page for your products, working with whoever runs your checkout.
- 04
Pictures and stories to explore
Illustrations that reveal a story when you hover over them, or a hidden treasure hunt.
- 05
Live social posts
Your guests' own social media posts appearing on your site as they share them.
Do you need a web app, or a website?
A website tells people about your business. A web app lets them do something with it: book, buy, sign up, play. Most of what we build is a bit of both.
If your visitors only need to read about you and get in touch, a well-built website is enough. You probably need some app work if one of these is true.
Signs you need more than pages
- 01
Visitors need to book, buy or sign up
A table for Friday, a case of wine, a place on a waiting list.
- 02
Something changes faster than a page should
Menus, availability or stock that your team updates all the time.
- 03
It has to talk to another system
A reservation system, a shop, a checkout partner or a social feed.
- 04
You want people to stay and explore
A game, a hidden world or a story that rewards a closer look.

How we build a web app

“It’s been a total pleasure working with Beyond. They took something so hard to convey, and made it look effortless. The vision I had for Incognito was clear – and I’m so happy, so glad I picked Beyond to deliver it. They just got it. It looks and feels exactly right for us.”
BeU: one page builder behind a website for every region
BeU provides mental health support in several parts of England, and each region needs its own website. Instead of building every site from scratch, we built one editing system they all share, so a new region starts from a working site rather than a blank page. BeU's sites for Nottinghamshire, Norfolk, North Yorkshire and BeU Hubs all run on it.
The editing system, Sanity, comes with more than 30 ready-made sections, from page headers and FAQs to contact forms and urgent-help contacts. Starting a new region is mostly setup and content, which keeps the cost of each new site down.
What BeU's team can do without us
- 01
Build new pages
Stack ready-made sections, edit them on the live page and drag them into order.
- 02
Change the whole site in one place
Menus, footer, colours, urgent-help contacts and pop-ups are all set once for each site.
- 03
Write once, use everywhere
FAQs, testimonials and shared sections appear on any page that needs them.
- 04
Make their own forms
Choose the questions, and the answers go straight to the right inbox.

Websites with working parts
Web app development questions
What is web app development?
It's building the parts of a website that let visitors do something: book, buy, see this season's menu, play a game. It usually means connecting your site to another system, like a reservation system or a checkout, so the visitor can finish what they came to do in one place.
What's the difference between a website and a web app?
A website gives people information. A web app lets them act: log in, book, pay, play. The line blurs, because many websites have app parts inside them. If your visitors only need to read about you and get in touch, a well-built website is all you need, and we'll tell you so.
Can you connect our website to the booking system we already use?
Usually, yes. We link your site to your reservation system so bookings go straight into it. Moor Hall's guests, for example, book directly into the restaurant's own system from its website. Name your system on the first call and we'll find out how it connects before we put a price on anything.
Can you build a game or interactive campaign into our website?
Yes. We can turn an illustration into something visitors explore, hide a treasure hunt in it, or tell a story as people scroll. Features like these give visitors a reason to stay and to tell their friends. Tell us the idea, even if it's rough, and we'll work out what it would take.
What technology do you build web apps with?
Next.js and React for what visitors see, Sanity for the words and pictures your team edits, and whichever booking, shop or checkout system the feature depends on. Pages are prepared before they reach the visitor, which keeps them quick even when they're full of illustration and animation.
How do you scope a web app?
We write down every feature, screen and connection, and who each one is for, before design starts. You get a plan you can hold us to and a price against it. If you want to change something along the way, we work out what the change costs with you before doing it.
How much does web app development cost?
It depends entirely on what it has to do, which is why we write the plan first. Linking one booking form and building a full game for your site are very different jobs. You'll get a clear price against the agreed plan before any development starts.
How long does it take to build a web app?
It depends on the features and the systems involved, so the written plan gives you a realistic timeline before you commit. If there's a launch date or a season you're aiming for, tell us early and we'll plan the stages around it.
Do you build web apps for Hampshire businesses?
Yes. Our studio is in Southampton, and we built the booking site, with its live feed of guests' social posts, for Incognito, whose flagship bar is in Winchester. We also build for clients across the UK and abroad. Tell us what your site has to do and which systems it uses, and we'll start from there.
