Fenris Creations today announced that Carbon, the next-generation cross-platform game engine framework behind EVE Online and EVE Frontier, has fully completed its transition to being completely open source. Built and evolved over more than two decades, Carbon was created to support entire universes: persistent online worlds where tens of millions of players have travelled, fought, built, traded, and shaped their own stories across the vastness of space.
Carbon powers EVE Online’s single-shard universe, its player-driven economy, and some of the largest battles in video game history, including EVE Online’s Guinness World Record-setting multiplayer PvP battle with 8,825 players. Every line of code, every pixel, and every system shaped by Carbon has been developed to push the boundaries of living virtual worlds.
The open-source release now spans more than two dozen Carbon modules, covering major parts of the platform used by Fenris Creations to build and operate its games. This includes Destiny, Carbon’s physics simulation and pathfinding technology, which helped facilitate EVE Online’s record-breaking battles, and Trinity, Carbon’s graphics module, which sits at the heart of its large-scale sci-fi aesthetics. Other Carbon components support core engine functionality, networking, UI, audio, resource management, scripting, scheduling, and the tools required to create scalable online experiences.
“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.”
Unlike many game engines created for broad commercial licensing, Carbon was developed inside a live game studio to meet the needs of EVE Online and Fenris Creations’ wider portfolio. It was built for speed, scale, performance, and long-term operation, supporting large-scale player activity, community-built tools, technical evolution, and the realities of maintaining a living universe for more than 23 years.
For Fenris Creations, fully open-sourcing Carbon is the next step in a long history of collaboration with players and developers. EVE Online’s community has built around the game for decades through third-party tools, public APIs, economic analysis, corporation infrastructure, alliance logistics, and player-created services. Opening Carbon brings that philosophy closer to the foundation layer, giving developers, researchers, players, and builders access to technology they can use, contribute to, and build upon.
Carbon will continue to support Fenris Creations’ own projects, including EVE Online and EVE Frontier. For EVE Frontier, Fenris Creations’ in-development hardcore space survival MMO, open technology supports a broader vision of a moddable, player-shaped virtual world where builders can create systems, tools, and experiences that persist within the Frontier.
