A curated list of awesome deterministic simulation testing resources 😎

Completion-based I/O for Rust. No runtime, no hidden tasks.

Fork decisions into living simulations with 1,000 personalities. Watch alternate realities diverge and explore second-order effects.

A blank-slate, memory-safe, ultra-high-performance property-graph database in Rust — unified MVCC/time-travel/branches/replication over a fountain-coded commit stream, WCO+factorized execution, incremental everything, and deterministic auditable results.

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.

Plugging into async/await in .NET for the deterministic simulation of the application logic

Deterministic non-LLM A-Life cosmos on Tsotchke math. v0.23.0 adds race-safe Big Tree fruit/leaf food, a neutral social sanctuary, bounded ecology visits, and removes Xenomimic tether remnants. WebGL2/Three.js; consciousness/quantum metrics are classical proxies.

Echo is a WARP optic runtime for witnessed causal history, Continuum-compatible suffixes, bounded observation, and holographic readings.

A modern, open-source reimplementation of the Cultures game series

Deterministic simulation-to-telemetry framework in Rust: model systems, orchestrate runs, stream time-series data, and replay reproducible experiments.

A deterministic simulation and model testing toolkit for MoonBit with virtual time, seeded randomness, trace/replay, metrics, scenarios, and reusable model tests.

Deterministic AI simulation and diagnostics lab for Project Nova / HASHKRIEG — branch-independent matches, replays, metrics, movement tests, combat analysis and comparisons.

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.

Echtzeitstrategiespiel in der Command-&-Conquer-Tradition. Unity 6 + C#, deterministischer Unity-freier Simulationskern, offene Entwicklung. Arbeitstitel in Umstellung: Hashkrieg.

Modern Python/Pyxel port of the original ZX game

Echtzeitstrategiespiel in der Command-&-Conquer-Tradition. Unity 6 + C#, deterministischer Unity-freier Simulationskern, offene Entwicklung. Arbeitstitel in Umstellung: Hashkrieg.

A game engine in Rust, built code-first: fixed-timestep deterministic simulation, Vulkan rendering, and every capability operable from the command line. Early development - every module is at bootstrap maturity and says so.

Deterministisches Strategie-Sandbox-Spiel ueber Zellkolonien, Evolution, DNA und territoriale Kontrolle.

An idle/strategy toy: spread AS688, an unmanaged 10BASE-T repeater, across 20 real internet exchange points while the NOC's attention climbs toward the Great Deswitching. One self-contained HTML file — no build, no dependencies, no network calls — with seeded, replayable runs.
