Fenris Creations announced today that Carbon, their cross-platform game engine framework behind EVE Online (and EVE Frontier) is now completely open source.
Should be interesting for people to re-use and learn from, with it being able to support persistent online worlds that have seen insane space battles with thousands of players in them.
The press release noted how the full code release includes lots of different modules like Destiny, Carbon’s physics simulation and pathfinding technology, and Trinity, Carbon’s graphics module.
There’s plenty more including networking, UI, audio, resource management, scripting, scheduling and so on.
“Carbon was built for a very specific purpose: to support living virtual worlds that can endure for decades,” said Ben Hunter, Senior Development Director for Core Technology at Fenris Creations.
“It has carried EVE Online through more than 20 years of continuous operation, from everyday player activity to some of the largest battles in videogame history.
Open sourcing Carbon is about making that foundation visible, understandable, and useful to others.
It is a commitment to transparency, longevity, and the belief that the next generation of persistent worlds will be stronger when more people can study, challenge, and build on the technology beneath them.”
Formerly known as CCP Games, they went independent as Fenris Creations back in May 2026.
Nice to see more developers lean into open source – it benefits everyone.
