Web app and SaaS development for companies in Austria and the DACH region

LONI DIGITAL builds web apps and SaaS platforms for companies and start-ups in Austria, Germany and Switzerland. You meet your contacts in person in Austria, and we work with you in German or English. You get production-ready software on a modern, maintainable stack, and you own the code from day one.

Who it is for

  • Start-ups that want to turn an idea into a market-ready SaaS product
  • Small and mid-sized companies that want a custom web app instead of spreadsheets for their internal processes
  • Companies whose existing application has reached its limits and needs to be rebuilt
  • Teams without an in-house development department that need a reliable technical partner

What you get

  • A production-ready web app or SaaS platform that runs in the browser on every device
  • User management with roles and permissions, and for SaaS, multi-tenancy and subscription billing if you need them
  • A clean API and integrations with the systems you already use
  • Automated tests, reproducible deployments and hosting in the EU
  • Documentation and full access to the code, the repositories and every account

How we build your web app

  1. Discover: We clarify goals, users and workflows, and decide what the first version really has to do.
  2. Plan: We design the architecture, the data model and the interface, and agree on scope, timeline and budget up front.
  3. Build: We work in short iterations. Every week you see working software, not just status reports.
  4. Launch and iterate: We take the app to production, watch how it is used and keep improving it where it matters.

Typical projects

  • Customer portals where your customers manage orders, documents and invoices themselves
  • Internal tools that replace spreadsheets, email loops and paper forms
  • Booking and scheduling platforms with calendars, reminders and online payment
  • B2B SaaS products with subscriptions, teams and roles
  • Dashboards that bring data from several systems together in one place

Technologies

We work with a proven stack that many developers know and that you can keep running without us. On the frontend that means TypeScript, React and Next.js, on the backend Node.js or PHP with Laravel. For data we use PostgreSQL, MySQL, MongoDB or Supabase, Docker for reproducible deployments, and Hetzner servers in the EU for hosting. We only bring in new tools when they give your project a clear advantage.

Personal contact, our own development team

Your contacts are in Austria. We hold workshops and check-ins with you in person, in German or English, or over a video call if you prefer. Development happens in our own team in Leskovac, Serbia, and for technical questions you talk directly to the developers who build your application. Read how the collaboration works in detail on our page about working with us.

FAQ

Frequently asked questions

How much does it cost to build a web app?

It depends on the scope: the number of features, roles and integrations, and your security requirements. After a short intro call you get a fixed estimate or a clear range before development starts.

How long until a first version is live?

We usually ship a first usable version, an MVP, in 6 to 12 weeks. After that we keep building in weekly iterations, so you can see and test new features all along.

Which technologies do you use for web apps?

On the frontend we use TypeScript, React and Next.js, on the backend Node.js or PHP with Laravel, and PostgreSQL as the database in most cases. The choice depends on your project and on what your own team can maintain later.

Can I develop the app further myself or switch to another provider?

Yes. The code, the repositories and every account belong to you from the start, and we document the architecture and the deployment. Another team or your own developers can take over at any time, with no lock-in.
