We stay in mission control after launch, updates, monitoring, fixes and new features as you grow.

Send us a few lines about your project. We reply with honest advice on scope, timeline and cost.
Scope, timeline and a fixed price in writing. No hourly billing, no surprises later.
You see and approve the design before we build. Two feedback rounds are always included.
Clean, well-structured code with regular progress updates. Tested on real devices, not just in theory.
We deploy, hand over everything, and stay around, 30 days of free aftercare on every launch.
Jupiter s.r.o. is a software studio built by engineers who care about how things work, not just how they look. We take an architecture-first approach: every decision is made with performance, clarity and long-term evolution in mind.
In three years we've shipped 20+ production systems, from web platforms and mobile apps to automation pipelines and data products, across a range of industries.
Architecture, data flow and long-term behaviour come before the first line of code.
Every choice is intentional, from tech stack to the last pixel of the interface.
Clean, testable implementations with performance and security built in, not bolted on.
We support what we build and evolve it as real-world usage teaches us more.
