Fenris Creations has made two decades of proprietary game tech public on GitHub, Carbon, the game engine, including the rendering and physics modules built to handle thousands of concurrent players.
Fenris Creations has officially released the source code for Carbon, the proprietary cross-platform game engine framework that has powered EVE Online and the upcoming EVE Frontier for over two decades. The official open-source codebase release and press announcement occurred on 1 July 2026, with the studio making more than two dozen modular components available to the public via GitHub.
This allows developers and researchers to inspect, learn from, or modify the low-level architecture behind an engine specifically designed to handle massive, single-shard online worlds with thousands of concurrent players. The full repository release includes three core properties:
- Trinity: Carbon’s core graphical rendering engine, responsible for the signature, sweeping space aesthetics of the EVE universe.
- Destiny: The engine’s dedicated physics simulation, collision computation, and pathfinding technology, engineered to compute massive, multi-player interstellar space battles.
- Core Modules: Complete open-source repositories covering low-level C++ architectures, networking (CarbonIO), user interfaces (CarbonUI), spatial audio, resource distribution pipelines, and Python scripting hooks.
While these core pillars anchor the release, the actual GitHub repository lists several highly specific subsystems that will particularly fascinate developers:
- Carbon Scheduler: A custom Python extension built to provide Stackless-like deterministic scheduling and channel messaging for Greenlet coroutines, allowing vanilla CPython builds to handle massive simulation queues smoothly.
- Spatial Audio Object Clustering: A custom Wwise plugin developed to dynamically group and manage spatial audio objects based on proximity—essential for keeping systems from crashing when thousands of lasers and explosions fire simultaneously.
The vast majority of the core components are published under the highly permissive MIT License. Only two specific sub-modules utilise alternative licensing structures: the Apache License 2.0 and the Python Software Foundation (PSF) License.
While the underlying game engine framework is completely free to download, study, and fork, EVE Online’s live game logic, art assets, official server binaries, and proprietary database components remain strictly private and commercial.
