First gitlab project, making an entire DirectX12 game engine entirely in Zig. I have not worked with Zig before so this will be entirely new to me. Might not start for a bit.

The Uncertain Machine is an open-source, AI-powered scientific simulation platform where players learn by interacting directly with dynamic models of reality. Instead of memorizing facts, users explore physics, biology, chemistry, and complex systems through experimentation, curiosity, and play. Built for all ages and skill levels, it adapts explanations in real time, turning every interaction into a discoverable, replayable learning experience where science is something you do, not something you read. https://roxanneardary.com/the-uncertain-machine/

A modular open-source investigative simulation platform where players use constitutional reasoning, structured evidence systems, and multiplayer collaboration to solve complex civic, legal, and criminal cases through logic-driven gameplay. https://roxanneardary.com/the-evidence-constitution/

GrowLocal is an open-source, AI-assisted, modular town simulation engine that models how real communities can grow and sustain themselves using local skills, resources, and cooperative systems. It transforms real-world towns into living simulations where economy, environment, infrastructure, and human activity interact dynamically, enabling users to explore sustainable development, emergent micro-enterprises, and community-driven planning. https://roxanneardary.com/growlocal/

EarthRoot Network is an open-source, AI-assisted infrastructure design system that generates location-aware, modular renewable energy and material solutions. It analyzes local environmental conditions, material availability, and cost constraints to produce optimized, buildable designs tailored to each region. Built around a modular architecture and continuous learning loop, the system enables adaptive, lifecycle-aware infrastructure planning that evolves through real-world deployment data under an AGPL 3.0+ open-source framework. https://roxanneardary.com/earthroot-network/

Infinity Arena is an open-source, AGPL 3.0+ modular fighting game where players create customizable male-and-female fighter pairs, design unique combat styles, and build synergistic abilities through fusion, DNA evolution, and modular weapon systems. Built as both a competitive fighting game and a community-driven creation platform, it empowers players to craft, share, and evolve fighters, combos, and entire combat systems in an infinite, expandable arena. https://roxanneardary.com/infinity-arena/

DesignFlux is an AGPL 3.0+ open-source engineering platform that combines physics-based simulation, AI-assisted design, manufacturing planning, and collaborative development into a unified ecosystem. Built for engineers, researchers, manufacturers, and innovators, DesignFlux provides modular tools for thermal engineering, aerospace systems, advanced materials, and future technology development, helping teams move from concept and simulation to validation and production. https://roxanneardary.com/designflux/

The open knowledge agent — codice del prodotto (Apache-2.0).

Weave Foundry is an open-source AI-driven fabric intelligence system that transforms creative ideas into real, buildable garments by connecting design, material science, and real-world resource sourcing. It enables users to generate modular clothing designs, compare material costs locally and online, receive step-by-step construction guidance, and evolve garments through repair and reuse, creating a complete lifecycle for clothing from imagination to physical reality. https://roxanneardary.com/weave-foundry/

VectorMeter is an open, modular metering and resource accounting system built on the Open Metering Specification (OMS) that provides immutable, auditable tracking of compute, time, and infrastructure usage across AI systems, cloud environments, and physical-world services. It enables deterministic billing, per-agent resource attribution, and verifiable audit trails so that every measured action can be traced from execution to invoice with full transparency and compliance support. https://gitlab.com/Roxanne_Ardary/vectormeter

Ruby on Rails CRM platform http://www.fatfreecrm.com

Forked from fatfreecrm/fat_free_crm

VaultCore OS is an AGPL-3.0+ financial intelligence platform that continuously verifies federally insured banks and credit unions, aggregates their financial products, and tracks real-time interest rates with full regulatory sourcing. Built as an open infrastructure system, it combines structured financial data, audit-grade verification pipelines, and an AI interface to deliver accurate, transparent, and source-backed insights into the U.S. banking system. https://roxanneardary.com/vaultcore-os/

TraceGraph OS is a scientific intelligence operating system for modeling, tracking, and reproducing how scientific discovery actually happens. It combines causal reasoning, temporal modeling, provenance tracking, and AI-driven simulation to ensure every hypothesis, experiment, and result is fully traceable, reproducible, and grounded in evidence. Built for materials science and extensible to broader research domains, it turns scientific workflows into structured, verifiable graphs that capture not just outcomes, but the full lineage of how knowledge is formed and evolves over time. https://roxanneardary.com/tracegraph-os/

ThreadGraph is an open-source, AGPL-3.0+ modular agent swarm runtime that transforms complex tasks into executable, graph-structured workflows. It orchestrates multiple specialized agents, tools, and memory systems through a dynamic execution graph, enabling parallel reasoning, structured decomposition, and fully observable workflows. Designed for extensibility and composability, ThreadGraph turns agent-based systems into scalable, reproducible infrastructure rather than linear prompt chains. https://roxanneardary.com/threadgraph/

Stratum is an AI governance layer for MCP systems that sits between model intent and tool execution. It enforces permissions, policies, context controls, approval workflows, sandboxed execution, and audit logging to ensure every action taken by an AI system is authorized, traceable, and constrained by explicit rules before it runs. https://roxanneardary.com/stratum/

Saturnet is a modular, AI-driven astronomy intelligence system that transforms the night sky into real-time, interactive knowledge. It identifies stars, planets, satellites, and space stations while providing live AI narration, predictive sky modeling, anomaly detection, and deep time simulation. Built as an extensible AGPL-3.0+ platform, Saturnet combines visualization, multi-agent AI reasoning, and a plugin ecosystem to help users understand and explore everything happening above Earth. https://roxanneardary.com/saturnet/

RoadCraft is an open-source AI motorcycle copilot system that combines helmet-based intelligence, real-time sensor fusion, and vehicle control integration to enhance rider safety without removing human control. It provides optional AI assistance for navigation, hazard detection, and emergency intervention, while supporting advanced features like V2X communication, stabilization systems, and edge-based processing. Built under the AGPL-3.0+ license, RoadCraft is designed for collaborative development of next-generation intelligent riding systems. https://roxanneardary.com/roadcraft/
