Experimental General-Purpose Entity Component System for Zig

Built with the use of Kilo Code and Claude 4.5 Opus

StaticECS is a compile-time configurable ECS framework that leverages Zig's comptime capabilities with the goals to generate highly optimized, zero-overhead entity component systems tailored to exact application needs.

This project is an attempt to leverage modern AI and Kilo Code to develop a pre-deisgned by a human ECS, Using comptimes and dead code elimination to allow it to work both as a general purpose single thread ECS in games, data pipelines, and simulations As well as provide abstractions to extreme performance multi-core systems and state management, to be used as a new "concept" of designing synchronous and asynchronous processes.

• Core ECS (World, Entity, Archetype, Query)
• Blocking and evented execution backends
• Work-stealing parallel scheduler
• Command buffers and deferred operations
• Multi-world coordination with lock-free transfers
• Entity ownership calculation strategies

• GPU compute executor - Placeholder only, returns error.GpuUnavailable
• SIMD worker pool - Sequential fallback, no actual SIMD intrinsics
• Cluster coordination - Framework only, no network transport
• External thread pool - Incomplete, tasks don't execute

This is an experimental project exploring the boundaries of compile-time ECS architecture. The framework demonstrates:

• Comptime type generation for zero-cost abstractions
• Platform-specific optimizations (io_uring, NUMA, huge pages)
• Optional adaptive runtime backend selection
