simulation-testing

Open-Source Agent Observability & Evals for AI Platform teams. Trace, test, route and govern every agent & coding assistant in the company.

Marionette is a deterministic simulation testing (DST) library for Zig.

A tutorial about how to apply property-based testing to stateful systems.

Test mode for your integrations, built for the way agents build

Deterministic Simulation Testing (DST) framework for TypeScript & Node.js. Reproduce distributed systems race conditions, network partitions, and heisenbugs bit-for-bit from a single integer seed. Inspired by FoundationDB & TigerBeetle.

A tool for comparing the design and analysis of surveys by simulating spatially-correlated populations

Raft consensus in pure Python with a deterministic fault-injection simulator and a linearizability checker

Memory for AI agents - entity extraction, dual retrieval, and evolution tracking

IX-HapticSight: open safety authority for AI-controlled robots/XR. RGB-D perception→3D hazards→ALLOW/MODIFY/DENY physical action, with consent, force/tactile/proximity/thermal gating, ROS2 control, recovery, WebXR, replayable evidence & 183 tested checks. MIT + Responsible Use.

Deterministic simulation testing (DST) for Go: run a distributed system on a simulated network, disk and clock inside go test, inject faults like partitions, crashes and failed fsyncs, and replay any failing run exactly from its seed. Built for AI coding agents and people.

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.

Idiomatic spec library for javascript

Testing the multivariate observer effects (MOE) framework

Find reproducible qualitative simulation transitions and turn them into pytest regressions.

An infrastructure-to-vehicle (I2V) wireless speed-control system that dynamically restricts maximum vehicle speed in designated safety zones (school zones, municipal limits, construction areas) using Sub-GHz RF beacons and Drive-by-Wire throttle interception.

This repository contains the multi-physics validation models, mechanical-thermal calculations, and trajectory telemetry for a next-generation high-RPM internal combustion engine powertrain.

Deterministic simulation testing for AI agents. Runs an agent inside a fake world where tools fail on purpose, and measures how often it claims to have done something it didn't — or does it twice.
