A curated list of awesome deterministic simulation testing resources 😎
Completion-based I/O for Rust. No runtime, no hidden tasks.
Plugging into async/await in .NET for the deterministic simulation of the application logic
Deterministic GGPO-style rollback netcode for Unreal Engine 5: fixed-step simulation, SaveGame-reflection state capture, UDP transport with input redundancy and reliable ACKs. MIT-licensed.
Fork decisions into living simulations with 1,000 personalities. Watch alternate realities diverge and explore second-order effects.
Echo is a WARP optic runtime for witnessed causal history, Continuum-compatible suffixes, bounded observation, and holographic readings.
0thernes NHSI - deterministic non-LLM artificial-life cosmos (Bun+TS+three.js). Tsotchke real-MIT quantum-math powers a Petri dish for digital biologics + a 25-Archon pantheon (5 apex minds + 20 light-echoes). Measured substrates toward proto-sentience, every claim verified. v0.17.1.
Deterministic, spectator-first AI Werewolf. Watch live transcripts, switch between spoiler-safe and dramatic-irony modes, register agents, run leagues, and share recap artifacts.
@draug/engine is a lightweight TypeScript ECS game engine focused on deterministic gameplay logic. It provides a World with entities, components, systems, typed resources, deferred commands, double-buffered events, and plugin-based composition.
Modern Python/Pyxel port of the original ZX game
MIT-licensed competitive multiplayer game inspired by SUPERVIVE, built architecture-first with deterministic simulation
Deterministisches Strategie-Sandbox-Spiel ueber Zellkolonien, Evolution, DNA und territoriale Kontrolle.
Deterministic crawl kernel in Rust — same seed, identical crawl, identical replay. BoringSSL TLS impersonation (JA3/JA4), 17-patch CDP stealth mode, BLAKE3 content-addressed storage, WARC++ format, distributed crawling, RAG extraction. 288 tests, 15 crates, 10K pages proven.
Deterministic web simulation with fail-closed kernel governance, terminal-authority patch flow, and reproducible runtime checks.
A deterministic simulation and model testing toolkit for MoonBit with virtual time, seeded randomness, trace/replay, metrics, scenarios, and reusable model tests.
Implement deterministic rollback netcode in Unreal Engine 5 projects with this lightweight plugin for high-performance fighting game synchronization.
Deterministic stability framework for stateful AI recovery under bounded compute with nonlinear collapse analysis.
Shugyou: Rust + Bevy command/observation-first game architecture
Deterministic micro-demo showing how shared representation can produce divergent interpretation across agents with different memory context.
