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