WebKitX enables legacy Windows applications to use modern HTML5 user interfaces without rewriting their existing code. It integrates a full Chromium engine into COM-based applications via a native ActiveX control, while running the browser engine out-of-process for stability and isolation. WebKitX is a production-ready component designed for enterprise, banking, government and industrial systems where reliability is critical.
Trusted for over 10 years in mission-critical enterprise, government and industrial systems

Licensing
WebKitX is licensed per developer workstation and build server for development purposes. Applications deployed on physical desktop environments do not require additional run-time licensing. Any hosted, SaaS, terminal-based or internal enterprise deployment requires an annual run-time subscription. Hardware/OEM distribution is licensed separately under a volume-based model.
