Source: Fabric Engine
Version 1.0 of Fabric Engine is available for Windows, Mac OS X and Linux, but it can also be used in browsers (Firefox and Chrome), server-side and in cloud environments. The engine works by allowing developers to use special interfaces and a high-performance scripting language called KL for performance critical parts of the code; for the rest of the application they can continue to program in one of the supported scripting languages. FabricEngine say this does not require specific HPC skills or C++ experience.
The Fabric Engine core and language bindings are made available as open source under the AGPL v3 license, with commercial licensing options available on request and paid-for support options for developers. Version 1.0 is available to download from the company's site.
