Why ByggCode

Craftsmanship, not a corporate machine

Direct & personal

No project manager in between. You talk directly to the developer who writes the code.

Solid quality

Handcrafted precision instead of copy-paste solutions. Every detail is built to last.

European standard

GDPR-compliant, EU-based, reliable. Your data and your project stay on European ground.

Flexible & fast

Small projects start in days, not weeks. Short paths, quick decisions, real momentum.

About

The studio behind ByggCode

ByggCode Studio is a software studio based in Sweden. We build apps, websites and digital solutions for small and medium-sized businesses — mainly in Germany and Sweden.

It all started over 20 years ago — with a first website, written by hand, line by line. Today we work full-stack: from the native iOS/Android app to the Linux backend server. Our best-known project is PrimeMap — an explorer app with over 4 million historical places worldwide.

A small studio with a direct line — for you that means short paths, fast decisions and no layers in between.
