What actually is a web app

A web app is a program that runs in the browser. There's nothing to install, and it works on a laptop just as well as on a phone. Unlike a website, it doesn't just show content, it gets tasks done: booking appointments, calculating prices, managing orders.

  1. Runs everywhere

    In the browser on every device, without an app store and without installation.

  2. Works with data

    Logins, bookings, documents: stored securely and only visible to those who should see them.

  3. Grows with you

    We start with the essentials and add new features when you need them.

How your web app comes to life

  1. Conversation and requirements

    We look at your day-to-day: what is currently costing you time, who should use the app and what does it absolutely have to do at the start?

  2. Concept and clickable prototype

    Before we program, you see what the app looks like and how it's used. That way you notice early whether it suits you.

  3. Development in stages

    We build step by step and regularly show you where things stand. Your feedback flows straight into the next stage.

  4. Launch and support

    We take the app live and explain everything calmly. If you like, we then take care of maintenance, hosting and new features.

Built with modern technology

Your web app is built with the same tools big platforms rely on. Which of them suit your project, we decide together if you like.

  • Next.jsThe framework we build websites and web apps on. It ensures fast load times and good visibility on Google.
  • ReactThe foundation of the interface. Small building blocks become pages that feel smooth to use.
  • TypeScriptJavaScript with fixed rules for data. Many errors show up while programming, not only when your visitors hit them.
  • Tailwind CSSA system for the look of the site. Spacing, colours and fonts stay consistent everywhere.
  • GSAPA library for animations. Elements move softly and smoothly, even while scrolling.
  • Node.jsRuns JavaScript on the server. This is where forms, interfaces and everything in the background run.
  • PostgreSQLA proven database. It stores customers, bookings or articles securely and retrieves them quickly.
  • SupabaseDatabase, logins and file storage from a single source. That gets the foundation of a web app up faster.
  • PrismaThe link between code and database. Makes queries safe and easy to follow.
  • StripeA payment provider for cards, SEPA direct debit, Apple Pay and more. It lets your site accept payments securely.
  • SanityA flexible CMS. You maintain text and images in a clear interface, without any code.
  • Payload CMSA CMS built right into your Next.js site. Content and website live in one place.
  • StrapiAn open source CMS that can also run on your own servers. Good if your data should stay with you.
  • StoryblokA CMS with a visual editor. While editing, you see right away what the page will look like.
  • VercelThe platform your site runs on. It's delivered quickly worldwide and updated automatically after every change.
  • DockerPackages an application with everything it needs. That way it runs equally reliably on any server.
  • ResendSends emails from your site, such as confirmations or contact enquiries, so they reliably reach the inbox.
  • ShopifyA platform for online shops. You manage products, orders and shipping in one place, and the shop matches your brand.
