Why SWT Evolve?

Your SWT/Eclipse RCP application runs critical workflows, and users now expect crisp, responsive UIs across Windows, macOS, Linux—and even the browser. Full rewrites to meet these demands are slow, risky, and expensive, often causing feature drift, constant context-switching to a new stack, and delayed timelines.

SWT Evolve replaces the legacy renderer with a modern engine while keeping your existing Java code intact. The result: a fully modern, responsive application with zero rewrites, full SWT API compatibility, and desktop + browser targets—all delivered in a single week so you can start delivering value immediately.
