WebKitX - Chromium ActiveX Control

Embed modern HTML5 UI using CEF in COM, Win32 and HMI/SCADA systems

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.

Key Features

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.

Licensing Terminology

ISV (Independent Software Vendor): Organizations developing and distributing commercial software products to external customers.
Physical Desktop: Single-user installations on end-user machines without remote access or shared execution.
Hosted / SaaS / Terminal: Any multi-user, remote-access or shared environment, including SaaS platforms, web-based systems, virtual machines, Remote Desktop, Citrix and application servers.
Internal (Intranet) Systems: Enterprise or government applications (e.g. HMI, SCADA, back-office systems) accessed by multiple users, even when deployed on local infrastructure.
Embedded / OEM: Software distributed as part of hardware products or appliances.
Developer License: Required per developer workstation and build server for design, development and compilation.
Run-Time License: Required for hosted, SaaS, terminal-based and internal deployments, based on subscription or volume licensing.
