Developing Graphics Software for Web-based BIM, Engineering and Medicine


xeokit SDK - Powering 3D Engineering Graphics on the Web

Get your IFC and CAD models on the Web using an open source toolkit of production-proven JavaScript components that save you costly research, development and maintenance.

The xeokit SDK powers the 3D IFC viewer within OpenProject, the world's most popular open source management software.


I'm Lindsay Kay, a software engineer developing browser-based 3D solutions for BIM, engineering and medical visualization.

Originally from Christchurch, New Zealand, I’ve lived in Berlin, Germany since 2011. I graduated with a degree in computer science from the University of Canterbury in 2005.

I'm now a full-time member of the team at Creoox AG. Together, we are developing the xeokit SDK, an open source SDK for viewing large AEC and BIM models in the browser.

Get in contact with us if you need a full-precision, high-performance, open source solution for viewing your BIM in the browser, or check out some of my previous work here at xeolabs.


We were really happy to work with Lindsay as he helped us increase our viewer’s quality and performance a lot. It was enjoyable to see a continuous incoming stream of quality JavaScript code coming our way. I recommend contracting with Lindsay without reservation. Stéphane Mor , CTO at BIMData, Lyon, France
