bozoslav/crabbyengine is a 2D/3D game engine written in Rust. The latest release in the repository is v1.0.0. What changed in this version is not separately listed in the provided material. The repository description and README present parallel ECS, hot reload, an in-game inspector, and AI agent control as the main features. The README describes the engine as aiming to simulate millions of objects.
The engine is built to update assets and code while the game is running, and to let you inspect game state in the in-game inspector. It also provides a separate simulation clock. With the MCP server, AI agents can run the game and inspect or modify entities. The same project also supports web execution and a C++ API. The license is Apache-2.0. This combination focuses on letting agents directly handle game physics and simulation.
However, on the basis of the published evidence alone, it is hard to judge real performance. The README is recorded as containing figures for large-scale simulation and rendering performance, but the figures themselves and the measurement conditions are not in the provided material. The repository has 4 stars, and the momentum of the scoring data is 1.1. The feature descriptions are concrete, but the information backing performance and use cases is limited, so large-scale processing capability is better read as a goal until separate evidence is confirmed.
