OpenTwin Information

OpenTwin is an open initiative of United Cities focused on making simulation, scenario testing, and decision support more accessible to the people shaping cities, infrastructure, climate resilience, and the built environment. We believe many of the most important decisions are made before projects begin—when uncertainty is highest and information is hardest to access. Yet the tools needed to evaluate options, understand trade-offs, and explore potential outcomes often remain expensive, fragmented, or limited to specialists. OpenTwin explores a different approach. Through technology prototyping, collaborative research, and capacity building, we develop and test practical methods for helping communities, organizations, and institutions make more informed decisions about the future. Our work spans: • Simulation and scenario testing • Spatial intelligence and geospatial analysis • Climate, infrastructure, and urban systems • Decision support and public-interest technology • Open knowledge, tools, and methodologies We collaborate with cities, researchers, planners, technologists, community organizations, and industry partners to explore how emerging technologies can improve the way decisions are made across the built environment. Our objective is simple: help people make better decisions about the built world.
