nautechsystems / nautilus_trader

Production-grade Rust-native trading engine with deterministic event-driven architecture

tangency-labs / solidcore

A Rust port of NVIDIA's SMLib B-rep kernel (CAD subset): safe, deterministic, wasm-compatible

copper-project / copper-rs

Copper is an operating system for robots - build, run, and replay your entire robot deterministically.

obeli-sk / obelisk

Durable & Deterministic Workflow Engine

flox / flox

The Deterministic Foundation for your SDLC

wasmi-labs / wasmi

WebAssembly (Wasm) Interpreter - An efficient, lightweight, and deterministic WebAssembly interpreter for embedded systems and plug-in runtimes.

archestra-ai / OpenAPPA

Deterministic guardrails that don't break agents

facebookexperimental / hermit

Hermit launches linux x86_64 programs in a special, hermetically isolated sandbox to control their execution. Hermit translates normal, nondeterministic behavior, into deterministic, repeatable behavior. This can be used for various applications, including replay-debugging, reproducible artifacts, chaos mode concurrency testing and bug analysis.

ThousandBirdsInc / chidori

The agent framework where every run is durable, replayable, and resumable by default.

skymanbp / autoshade

AI-assisted RAW photo developer: GPT vision advisor proposes an EditRecipe, a deterministic Rust engine renders it — Lightroom-compatible XMP sidecars, 24 RAW formats + baked images, measured (not guessed) Lightroom mask geometry, local GUI/web UI, AI denoise & segmentation sidecars

Sollimann / bonsai

Rust implementation of behavior trees for deterministic AI (now with Python bindings)

samvallad33 / vestige

Think before doing, prove before saving. Vestige is a local, deterministic safety kernel for AI agents. Every memory write and agent action is recorded in Strata, an append-only log, so you can see exactly what your agent did and why.

rust-lang / rustc-hash

Custom hash algorithm used by rustc (plus hashmap/set aliases): fast, deterministic, not secure

nwiizo / suiko

日本語文書の自然さと読みやすさを再現可能に診断するRust CLI / Deterministic diagnostics for natural and readable Japanese writing

balaurengine / balaur

A 2D & 3D node-based game engine, fully deterministic, with scripts that reload in milliseconds.

fzakaria / rewindvm

Deterministic Linux VMs you can scrub, rewind and fork. Find and replay flaky builds and tests.

dshbox / cordis-rs

A typed runtime for long-lived, plugin-oriented Rust applications — lifecycle, exact service placement, typed events, deterministic cleanup, scopes, and isolation.

Pixel-CLI / pixel

A tool that replaces everything that can be deterministic in repository work: search, symbols, callers, task scope, history, review and Git from one local CLI, so your AI coding agent spends its tokens on the hard part.

renew-engine / renew

renew engine: an AI-first game engine in Rust, built to be operated. Bit-deterministic fixed-timestep simulation in Q47.16 fixed point, Vulkan rendering through ash, and every capability driven from the CLI with schema-versioned JSON. 29 modular crates, desktop and mobile. Apache-2.0. Early development.

CasualOffice / opendoc

Apache-2.0, embeddable, local-first editor for Word documents, and the deterministic Rust engine underneath. Reads and writes DOCX and ODT, exports PDF, HTML and Markdown, and runs natively, headless, or in the browser as WebAssembly. An open alternative to ONLYOFFICE Docs.

Dicklesworthstone / franken_accounting

Universal, evidence-native double-entry accounting system of record in Rust on FrankenGraphDB: bitemporal, append-only with first-class restatements, exact money algebra, counterfactual branches, in-database forensic analytics, outsider-verifiable proofs, and an agent-first CLI/MCP surface for CPAs, regulators, litigators, and investigators.

tdaylan / NoiseScope

A control instrument for handshake state machines - lint protocol models, replay transcripts, and fly deterministic mutations until a trace diverges.
