• IFC.js is a javascript library for handling IFC data
• Xeokit is a Web Programming Toolkit for AEC Graphics, including IFC
• IfcOpenShell is a collection of C++ libraries with Python bindings and integration with FreeCAD and Blender
• IFC-dotnet is a C# IFC library for .NET Core under an MIT license (innactive for several years)
• XbimEssentials is a .NET library to work with data in the IFC format. This is the core component of the Xbim Toolkit and under a CPPL license
• GeometryGymIFC C# classes to generate and parse OpenBIM IFC (Industry Foundation Class) files. (GeometryGym is a whole suite of tools and plugins)

There is a discussion on the forum comparing some of these libraries. The IfcOpenShell project has done a study to see exactly how much each open source technology currently is capable of scaling.
