Polycode vs Duality

Polycode uses Lua and C++ to create native applications for Windows, Mac, and Linux. Mobile platforms are planned for the future.

Polycode is free and open source (released under the MIT license). The source code is freely available on GitHub.

Recently, the editor and its integrated tools have been released in compiled form. Features coding and scene editing in one application.

Polycode is distributed in a C++ form as well as with IDE. And there's an additional LUA-based scripting system.

The full source code is available on GitHub, where the framework is actively developed. All of the editor, core and plugin code is written in C#.

Duality includes a powerful visual editing system that can be used for previewing, integrating, editing and testing game content.

Because both Core and Editor are completely plugin-based, Duality not only incorporates a clean and modular design, but is also very extensible - even if it wasn't Open Source. In fact, most of the standard editing capabilities comes in form of Editor plugins.

It can be configured to serialize all data in a text-based format, which has been structurally optimized for version control systems.

It has been used in a production environment without burning the place to the ground. Supposedly artist-proof editor workflow with an API for tailoring the system to fit your team.
