ResponseOS is an open-source platform for reproducible clinical research analysis that re-examines medical studies to identify what truly drives patient outcomes. It aggregates and normalizes clinical trial data, applies Bayesian and meta-analytic methods to measure treatment effects against placebo signals, and highlights areas requiring further biological investigation. Designed for transparency and auditability, ResponseOS builds a continuously updated knowledge system where all analyses are versioned, reproducible, and open to scientific scrutiny under the AGPL-3.0+ license. https://roxanneardary.com/responseos/

Chainly is an open-source AI-powered data flow intelligence system that traces what happens to user data after login events across the web. It builds evidence-based graphs of how information moves between first-party services, third-party vendors, and data brokers, revealing real-world data sharing that is often hidden behind privacy policies. By combining network tracing, graph analysis, and AI-driven entity resolution, Chainly turns invisible post-login data propagation into a transparent, auditable system. https://roxanneardary.com/chainly/

MediscopeLedger is an open-source platform that provides full transparency in healthcare by combining verified product and provider data, AI-powered patient and provider insights, procedure pricing, and compliance monitoring. Patients can compare providers by total cost, safety, and outcomes, while providers receive automated alerts for pricing transparency and regulatory compliance. Built for accessibility, safety, and trust, MediscopeLedger empowers informed healthcare decisions. https://roxanneardary.com/mediscopeledger/

The Foundation for Deterministic Computing (FDC) is an open standards initiative dedicated to building reproducible, auditable, and human-governed computing systems. It defines modular specifications for deterministic execution, verifiable intelligence, structured knowledge, and transparent decision-making. The foundation provides a framework for ensuring that computational systems operate with consistency, traceability, and accountability across all layers of software and intelligent infrastructure. https://roxanneardary.com/foundation-for-deterministic-computing/

DashHub is an open source, AGPL-3.0+ universal automotive dashboard platform designed to retrofit any vehicle—regardless of make or year—into a modular, connected, and upgradeable system.
