Why Delphi Is Still Relevant Today

Delphi (Object Pascal) has a loyal user base – especially in the German SME sector. Many business-critical applications have been running stably for decades. Native Windows performance, rapid development, and direct hardware access are strengths that modern frameworks often cannot offer.

The problem: experienced Delphi developers are scarce. When the original developer leaves, many companies face a serious challenge. We have over 20 years of Delphi experience and also take on software without documentation.

Modernization vs. Migration

Not every old Delphi application needs to be replaced. Often, modernization is the better path: updating to current Delphi versions, new UI frameworks (VCL/FMX), improved database connectivity, adding web services.

Migration to .NET, Electron, or web makes sense when: dealing with very old unstructured code, wanting cross-platform support, or when modern web technologies are needed. We provide honest advice on what is optimal for your situation.

All Delphi Versions Supported

We work with all Delphi versions:

Turbo Pascal, Delphi 1–7: Legacy maintenance and migration
Delphi 2005–XE8: Unicode migration, VCL updates
Delphi 10+: Modern development, FMX, REST
Lazarus/FreePascal: Open-source alternative

Everything About Delphi Development Costs

Costs & Budget

How much does a new Delphi development cost?

A simple desktop application: €15,000–30,000. A mid-range business application: €40,000–80,000. Complex industrial software: €100,000+. Delphi is ideal for high-performance Windows applications.

How much does maintaining existing Delphi software cost?

Depending on scope: €300–1,500/month. One-time bug fixes: from €500. Code analysis for takeover: from €2,000. Experienced Delphi developers are rare – we have over 20 years of expertise.

How much does migration to modern technologies cost?

Gradual migration: €30,000–80,000. Complete redevelopment: €50,000–200,000+. A hybrid approach is often the most sensible: keep core systems in Delphi, develop new modules with modern technologies.

Technology & Versions

Which Delphi versions do you support?

All versions since Delphi 5: D5, D7, 2005–XE8, Delphi 10+. Also Turbo Pascal and Lazarus/FreePascal. Migration to current versions is also possible.

Should I modernize or migrate my Delphi application?

It depends: well-structured Delphi code can often be modernized cost-effectively. With very old or poorly maintainable code, migration (e.g., to .NET, web) may be more sensible.

Is Delphi still future-proof?

Yes, Embarcadero continues to actively develop Delphi (FireMonkey, REST integration, cross-platform). For new projects, however, it is worth weighing against modern alternatives.

Takeover & Support

Why are Delphi developers so hard to find?

The language is less widespread than C# or JavaScript. Many Delphi developers have retired. We have over 20 years of experience and also take on undocumented projects.

Can you take over software without documentation?

Yes, after a code analysis (from €2,000) we assess the condition and maintainability. With well-structured code, the takeover is usually straightforward.
