How to Bring Your Object Pascal Applications to the Modern Web — Without Rewriting in JavaScript
Why Quartex Pascal is the smart choice for Delphi and Object Pascal developers
The Developer’s Dilemma
Many of us have spent years building rock-solid desktop applications in Object Pascal — whether in Delphi, FreePascal, or Lazarus. But today, customers and users increasingly demand browser-based applications, mobile-friendly UIs, and remote access to their tools.
Rewriting everything in JavaScript — or trying to learn frameworks like React or Angular — is a painful and expensive proposition. And while Delphi offers options like TMS WebCore or IntraWeb, they come with extra cost and complexity.
Common Pain Points
- You have years of valuable Object Pascal code — why throw it away?
- Your team is productive in Pascal — why force them to learn a new stack?
- Delphi’s web tools are complex and costly (TMS WebCore requires extra licensing).
- Pas2JS is too low-level for many developers.
- JavaScript frameworks change constantly — making maintenance difficult.
Enter Quartex Pascal — The Bridge to the Web
Quartex Pascal (QTX) gives Object Pascal developers a fast, clean way to build modern web applications — without abandoning Pascal.
- Stay 100% in Object Pascal.
- QTX compiles your code to modern, high-performance JavaScript.
- Outputs responsive HTML5, CSS3, and JavaScript.
- Runs in all modern browsers — no plugins, no emulation.
- Reuse existing Pascal business logic — no need to rewrite core code.
- No Delphi license required — QTX is a standalone system.
- No extra frameworks to buy (unlike TMS WebCore).
- Direct DOM integration — full control over your app’s behavior.
How It Works
With QTX, you can:
- Build your app in the QTX IDE.
- Design forms visually or in code.
- Write business logic in Object Pascal.
- Compile — and QTX outputs fast, small JavaScript + HTML + CSS.
- Your app runs natively in any browser — desktop, tablet, or mobile.
- You can also target Node.js for server-side development.
What You Can Build
- Modern web versions of legacy Delphi desktop apps.
- Internal dashboards and admin tools.
- Mobile-friendly line-of-business applications.
- Embedded web UIs for IoT and industrial devices.
- Progressive Web Apps (PWA) — installable apps on desktop and mobile.
- Browser-based UIs for existing backend databases.
Why It’s Better Than the Competition
| Alternative | Drawback |
|---|---|
| Delphi + TMS WebCore | Expensive licensing, complex setup, heavier runtime |
| Pas2JS | Too low-level, lacks polished IDE and dynamic UI tools |
| Smart Mobile Studio | Older architecture, less modern DOM integration |
| React/Angular | Requires full rewrite, retraining team, and ongoing heavy maintenance |
