Alpha Risk Review is a modular adversarial intelligence system that analyzes business plans by decomposing assumptions, stress-testing structural weaknesses, and simulating real-world failure scenarios. It identifies where a business is most likely to break, what conditions are required for success, and how confident the system is in its evaluation. The result is a structured, explainable risk assessment that transforms abstract business ideas into measurable, stress-tested outcomes.

SimGear - simulation libraries for FlightGear

HarvestIQ is an open-source AI-powered land intelligence and simulation platform that helps property owners optimize every square inch of their land for maximum productivity, profitability, and sustainability. By combining geospatial mapping, zoning law compliance, market forecasting, and user-defined skills and goals, HarvestIQ generates actionable, real-world land-use strategies and allows users to simulate outcomes before implementation.

FlightDynamics is an open, AI-native specification for launch planning, mission engineering, orbital dynamics, and space operations. It defines a modular, implementation-agnostic standard for modeling and optimizing every stage of a space mission lifecycle, from early mission design through launch execution, orbital operations, and end-of-life planning. Designed for local-first deployment with optional integration into distributed systems, FlightDynamics enables interoperable, explainable, and extensible mission planning systems without vendor lock-in.

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.

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.

The Modular Non-Invasive BCI Engineering Platform is an open-source, AGPL-3.0+ neuroengineering framework designed to unify wearable brain-computer interfaces, hardware abstraction, and real-time neural decoding into a single modular system. It enables developers to build, simulate, and deploy EEG-based applications through interchangeable wearable and hardware modules, supported by machine learning pipelines, sleep and dream state analysis, hardware development tooling, and legal assurance systems for design validation and compliance.

LAVE (Low-Altitude Vehicle Experiment) is an open-source research platform exploring human-scale hover in the sub-meter regime using distributed electric thrust, real-time stabilization, and fully transparent hardware and software systems. Built for reproducibility and experimentation rather than productization, it focuses on measuring the unstable transition between ground contact and sustained flight, with all telemetry, failures, and design iterations openly shared as part of the research process.

KineticKind is an open-source SUV platform designed to make entering and exiting a vehicle safe, comfortable, and dignified through intelligent seat-assist technology. By combining rotating lift seats, accessibility-focused engineering, and a fully open development model, the project reimagines mobility around real human movement rather than mechanical constraints. Built under the AGPL-3.0+ license, KineticKind invites a global community to collaborate on creating more inclusive transportation for everyone.

Circulis Aqua is an AGPL 3.0+ modular infrastructure design system for desalination, water purification, reuse, and geospatial distribution. It uses AI-assisted configuration to design scalable, plug-in water systems that range from residential units to municipal and regional grids. Built on a graph-based water flow model, it enables local-first optimization, closed-loop water reuse, and intelligent routing to ensure no water is wasted across interconnected infrastructure networks.

AETHER STAGE is a cinematic spatial intelligence system that transforms filmmaking into a structured, physics-aware, and fully directable simulation. It replaces prompt-based generation with a layered architecture of persistent 360° assets, mass-based spatial constraints, causal narrative systems, and a Director Override Layer that enforces creative intent above all simulation rules.

Applied Unknowns is an open-source action-adventure scientific sandbox where gameplay becomes structured contribution to a persistent, deterministic simulation. Players explore, experiment, and build systems that are measured, validated, and permanently integrated into the evolving world. Instead of traditional progression or disposable content, every meaningful action can become lasting infrastructure, shaping how the world functions for everyone.

Agility Ascension is an open-source dog agility training and competition simulation game designed for ages 5+. Players form a handler–dog team and progress through structured practice fields, distraction-heavy environments, advanced distance handling challenges, and competitive trials. The experience evolves from foundational skill-building into high-pressure performance scenarios shaped by the Leaf Module’s environmental effects and a modular progression system, ultimately leading into multiplayer global competition where teamwork, timing, and focus determine success.

Menura is a space plasma simulation code. It is built around a hybrid Particle In Cell (PIC) solver, running on Graphics Processing Units. More informations on https://menura.readthedocs.io
