Openfu.Inc is a small game consulting and software development shop, run by Udo and friends. Our expertise lies in custom software made in C, C++, C#, Python, and JavaScript. We support small studios and agencies with tools and optimizations. We love working with in-house games and engines, but we also have experience with the Unity and Unreal engines as well as common middleware and libraries.

You got the game - we'll make it run (and run well).
