Web applications

Web apps, dashboards and the APIs behind them

Fast, responsive web applications built with React, Next.js and TypeScript, plus secure backends and APIs that power your web and mobile apps together.

A web app is often the quickest way to put a product in front of users: nothing to install, instant updates and one link to share. It's also where admin panels, dashboards and internal tools usually live.

We build the front end and the backend together. The same API can serve your website, your iPhone app and your Android app, so features and data stay consistent everywhere.

FAQ

Common questions

Should I build a web app or a mobile app first?

If your users mostly work at a desk, or you need to validate an idea quickly, start with the web. If the product depends on the camera, location, notifications or daily habit, start with mobile. Many products need both and share one backend.

Can one backend serve web, iOS and Android?

Yes, and it's how we build: one API with one source of truth, so every app sees the same data.

Do you build marketing websites too?

Yes. Every one of our apps has its own fast, static product site with support and privacy pages.
