Why not just move to Theia or VS Code?

Eclipse Theia is a web-technology framework (TypeScript/HTML/CSS) for building IDEs. It runs in a browser or as a desktop app via Electron.

VS Code is an Electron/Chromium editor with an extension model in JavaScript/TypeScript. Porting features means writing VS Code extensions, not running SWT UIs.

vs.

The core difference is 100% SWT API compatibility. SWT Evolve provides a modern rendering engine that allows your existing application to run natively on the desktop or in a browser with zero code changes. This drop-in solution bridges the gap between your proven legacy code and the demands of a modern user experience without re-thinking workflows, and re-training teams on new tech stack.

Why companies pick SWT Evolve over a rewrite

Modern look & UX: pixel-perfect, themed UIs; 60/120 fps with GPU acceleration.

Cross-platform, cloud-ready: run native or in the browser without architecture upheaval.

Lower risk, faster ROI: avoid multi-month migrations and “feature parity” gaps.

Reduced development costs: Rewrites demand years of work, duplicate testing, and expensive retraining.

Zero rewrites, proven logic: Retain your entire SWT application logic and investment. Evolve updates the presentation layer without disrupting the stable core of your product.
