Puzzle Enterprise
Custom Web Development

When Off-the-Shelf Isn't Enough.

From complex features to fully custom platforms, we develop scalable web applications tailored to your exact needs: no limitations, just results.

Software that fits your process

Plugins and SaaS tools are great until your business needs something they can't do. Then the workarounds start: spreadsheets, manual exports and copy-paste between systems.

We build custom web applications that fit the way you work: customer portals, dashboards, booking and ordering systems, internal tools and integrations between the systems you already use. We work with modern, proven technology like Next.js, React and Supabase, and build for performance, security and growth from the first version.

Is This for You?

  • Your process doesn't fit an off-the-shelf tool
  • Your team copies data between systems by hand
  • You need a customer portal, dashboard or web app
  • You want a web app and a mobile app on the same backend

FAQ

Custom Web Development FAQ

When do I need a custom web application?

When your requirements don't fit existing tools, when you pay for several tools that don't talk to each other, or when the software itself is your product. If a good off-the-shelf solution exists, we'll tell you.

Which technologies do you use?

Mostly Next.js and React for the interface, Supabase with PostgreSQL for data and authentication, and React Native for mobile apps. We choose the stack for each project and explain why.

Can you build a mobile app as well?

Yes. With React Native we build iOS and Android apps that share the backend with your web application, so data and logic stay in one place.

Can you integrate with our existing systems?

Yes. We connect to CRMs, ERPs, payment providers and other services through their APIs, and build our own APIs where needed.

What happens after launch?

We monitor the application, fix issues, keep dependencies up to date and build new features as your needs grow.
