Delphi Development – Desktop & Legacy Applications

Professional desktop applications with modern Object Pascal technology. Native performance, rapid development, and cross-platform solutions for Windows, macOS, and Linux.

Expert Delphi Development for Desktop Applications

Delphi is still one of the most reliable tools for desktop apps. Many companies use it for daily work in manufacturing, logistics, healthcare and finance. Apps are compiled to native code. They are fast and need no extra runtime like Java or .NET. That suits tight resources and cases where startup must be instant.

We have used Delphi for over 15 years. We have built, maintained and modernized hundreds of apps – from small tools to large enterprise systems. We often help migrate old Delphi 7 (or older) apps to current versions so they work on modern Windows and get security and language updates.

Updating a Delphi app is often cheaper than rewriting it in another tech. With FireMonkey we can bring existing apps to macOS and Linux without rewriting all the logic. We give clear advice: when to stay on Delphi and when a different technology is better long term.

We work with VCL and FireMonkey, databases, REST APIs and cloud services. New app, migration to current Delphi, or new features on an existing app – we deliver solid results.

Frequently Asked Questions

Delphi Development

Delphi Today & Modernisation

Is Delphi still a sensible choice today?

Yes for maintainable Windows desktop apps, data-heavy tools and long-lived business software. Delphi offers fast development, native performance and a mature ecosystem.

Can you modernise our existing Delphi application?

Yes. We refactor legacy code, introduce modern UI (FMX, VCL updates), add APIs and integrate with web services. We keep the investment while improving maintainability.

How much does Delphi development or modernisation cost?

Small updates from around €3,000 excl. VAT; larger modernisation or new projects from €15,000 excl. VAT. We quote after a short assessment.

Do you support migration from Delphi to other technologies?

Yes. We can migrate to .NET, web apps or hybrid solutions when a full move is desired. We scope and plan the migration so risks are manageable.
