Astra ECS · C++20
A high-performance archetype ECS: over a billion iterations a second, with cache-friendly storage and zero-overhead abstractions.
One studio. The whole stack.
We don’t license an engine; we build it. Our games run on Arcane, our in-house C++23 engine, powered by Astra, Manifold2D and a carefully chosen open-source stack, all on Mosaic, our shared foundation.
The Game
Aphelyon
Our first game, in development
The Engine
Arcane
Our in-house C++ engine: rendering, tooling, ECS, physics, audio and profiling
The Foundation
Mosaic
Zero-dependency C++23 platform layer under Arcane, Astra and Manifold2D
Engines and libraries
Every layer, on GitHub.
Read the code, file an issue or build on it: each library has its own page and its own repository.
Arcane Engine · C++23
Our in-house 2D game engine, built around modern rendering, jobs, hot reload and the Astra ECS.
Manifold2D Physics · C++23
Deterministic 2D rigid-body physics modeled on Box2D v3: fast collision, constraints and game-ready simulation.
Mosaic Foundation · C++23
The zero-dependency foundation under every Starworks product: platform detection, deterministic SIMD, and the job, log and assert seams.
