FAQ

Web Application Development questions

More answers on our FAQ page.

Can you build an MVP for my startup?

Yes. We help you define a focused minimum viable product — the smallest version that delivers value — so you can launch, learn and build from real feedback.

What does the £135 Web Application Starter cover?

It covers initial application setup, a custom interface, core functionality planning and basic database/API planning. A complete SaaS platform is a larger project and is quoted individually.

Which technologies do you use?

We typically use React, Next.js and TypeScript on the front end, with Node.js and relational databases such as PostgreSQL on the back end. We choose tools to suit the project.
