Our technology: Laravel, PHP, APIs
We develop with Laravel – one of the most modern PHP frameworks. Laravel is stable, scalable and well documented. That means: your software runs reliably and can be maintained and extended long-term. For more demanding frontends and enterprise applications we also work with TypeScript and Angular – at united-domains, for example, across more than 3 million lines of code as part of the team.
Tech stack
Backend Laravel (PHP)
Frontend Blade, Vue.js, Alpine.js, TypeScript
Database MySQL, PostgreSQL
APIs REST, JSON

When is custom software worth it?
Not every problem needs a custom solution. But sometimes standard software is more expensive than expected – because it doesn't fit, because you need workarounds, because you have to adapt instead of the other way around.
Custom software is worth it when:
- You have processes that no standard software can map
- You need to connect multiple systems (ERP, CRM, shop)
- You need a customer portal or dashboard
- You want to automate recurring manual work
- You have a product idea you want to realise

Frequently asked questions
What does custom software development cost?
It depends on the scope. Small automations start at a few thousand euros, complex web applications can cost €20,000 or more. We give you a realistic estimate after the initial call.
How long does development take?
A small tool or API integration: 2–4 weeks. A complex web application: 2–6 months. We work iteratively, so you see first results early.
Why Laravel?
Laravel is one of the most mature PHP frameworks. It is well documented, has a large community and enables clean, maintainable code structures. For most web applications it's the best choice.
Can we continue development ourselves later?
Yes. We document our code and build in a way that another developer (or you yourself) could take over later. You are not dependent on us.
What happens after launch?
That's up to you. We offer maintenance contracts but are also available for one-off requests. No lock-in contracts.
