FAQ

How much does a custom web app cost?

Smaller web apps and portals typically cost £4,000–£7,500. Larger platforms with several integrations, complex permissions, or mobile apps usually cost £7,500–£10,000 or more. Changes to an existing app are usually billed at £50–£120 per hour.

What technology do you use?

Next.js and React for the interface, Node.js for APIs, and PostgreSQL, MySQL, or MongoDB for data, deployed with automated CI/CD. It's a mainstream stack, so it's easy to hire for later.

Can you work on our existing application?

Usually, yes. We review the codebase on a call and tell you honestly what state it's in and what it needs.

Do you sign NDAs?

Yes. We're happy to sign a mutual NDA before you share details of your product.
