Frequently asked questions

What is web application development?

It is the design and build of browser-based software - portals, dashboards and online services - including the backend, database and APIs that power it.

What is the difference between a website and a web application?

A website mainly presents information; a web application lets users do things - log in, submit, book, pay, manage data.

Will it work on mobile?

Yes. Every web application we build is responsive and tested on phones, tablets and desktops.

Do you also build marketing websites?

Yes - see our Web Development page for websites and e-commerce.
