Custom software development from Vienna.
JetCoders builds custom web applications for companies in Austria and the DACH region — working remotely or on site in Vienna. When standard systems are not enough, from replacing legacy software to creating internal web apps.
Custom web software with a clear job
We take on projects where web technology needs to create a concrete operational benefit: better usability, faster workflows, fewer technical leftovers.
B2B SaaS & web applications
Product interfaces, workflows and platform features that stay reliable in daily use and can be developed further with intent.
→ Example: OfficeToGo 02Frontend migrations
Existing interfaces are modernized step by step, for example from PHP to React, without putting avoidable pressure on live operations.
→ Example: clockodo 03Internal tools & dashboards
Web apps for operational teams: shipment tracking, user management, reporting and workflows in one place.
→ Example: SB Logistics 04Modernize software & replace legacy systems
Grown systems are renewed or replaced step by step while day-to-day operations keep running – as with OfficeToGo.
→ Software modernizationProven technologies, not a framework zoo.
We use modern web technologies that stay maintainable for teams and reliable in production.
How a project runs
The process stays pragmatic: understand first, shape the work properly, then deliver in short cycles.
Conversation & context
We clarify the goal, users, existing systems and the next decision that needs a reliable basis.
Scope & architecture
The scope is shaped so usable results appear quickly while later extensions remain possible.
Build in cycles
Development, review and alignment run in short loops. You see progress early, not only at the end.
Handover & maintainability
Code, decisions and operations are handed over in a way that keeps the application extendable after launch.
For maintainable projects with a direct line.
Custom development is worthwhile when a system needs to last, model real business logic and remain cleanly extendable over time. We work on mid-sized and larger projects.
A good fit
- modernizing existing systems
- bringing internal workflows into a web app
- developing established platforms over the long term
Not a fit
We don't build native mobile apps – we build web applications. For simple websites, Jet-Pages is the better route: our own product for multilingual websites.

01 What does it cost to have a web application developed?
It depends on the scope: number of workflows, integrations and existing code. Flat figures would be misleading — after a free intro call, you will receive an honest assessment of effort, costs and a sensible scope. More on the cost of custom software development
02 How does a project with JetCoders work?
In four steps: conversation & context, scope & architecture, implementation in cycles, handover & maintainability. You speak directly with the developers, not with sales.
03 Do you also take over existing projects?
Yes. Frontend migrations, performance work and modernization of existing applications are a core area — see the case studies on clockodo and Office to go.
04 Do you only work in Vienna?
We are based in Vienna and work with clients throughout Austria and the DACH region — usually remotely.
05 Which technologies do you work with?
With a deliberately lean, proven stack: React, Next.js, TypeScript and Astro — hosted in the EU.
