Quick answer

What is a custom web application?

A custom web application is software that runs in the browser and is built for a specific business need — a customer portal, booking platform, marketplace, SaaS product or internal tool. Unlike a website, it handles accounts, data and workflows. Unlike off-the-shelf software, it fits your process exactly and grows with you.

  • Accounts, roles and permissions
  • Workflows, data and integrations
  • Works on desktop, tablet and phone

Straight answers

Questions worth asking Questions worth asking

The things brands actually ask us before a build — answered properly, including the times the answer is that you do not need us.

  • How much does a custom web application cost?

    It depends on the number of user roles, screens, integrations and how complex the business rules are. An MVP costs far less than a full platform. After a discovery call we send a fixed, itemised quote.

  • How long does it take to build a web application?

    A focused MVP often takes eight to twelve weeks; larger platforms are built in phases over several months. You get a milestone plan with your quote and a demo every week.

  • What technology do you use?

    Usually React or Next.js on the front end, Node.js or NestJS on the back end, PostgreSQL or MongoDB for data, and AWS, Google Cloud or Vercel for hosting — chosen to suit your product and team.

  • Web app or mobile app — which do I need?

    A web app works on every device from one code base and needs no app store, which makes it the faster, cheaper start for most products. A native or cross-platform mobile app makes sense when you need device features, offline use or app store presence.

  • Who owns the code and data?

    You do. Once the project is paid in full, ownership of the custom code passes to you, and the hosting, database and accounts are set up in your name.

  • Do you support the application after launch?

    Yes. Every launch includes 30 days of fixes, and support plans cover monitoring, updates, security patches and new features.
