Machinations vs Stella Architect
Machinations keeps a system’s rules and assumptions visible while people build, Play and discuss an economy or complex system in one shared resource-flow diagram.
Machinations and Stella Architect at a glance
Stella Architect and Machinations both make models visible through diagrams, while offering different modeling environments. Stella Architect emphasizes system dynamics and multimethod modeling with interfaces that can be published for others to explore.

Who should choose which
Where Machinations may fit
Consider Machinations when a team wants a shared resource-flow diagram where rules and assumptions stay visible while people build, Play and discuss an economy or other system. Monte Carlo Forecasts, which Play a model many times to show the range of possible outcomes, run on Machinations’ cloud servers.
Where Stella Architect may fit
Consider Stella Architect when you need to build a system dynamics model, combine supported modeling paradigms, analyze sensitivity or feedback loops, and publish a tailored interactive model interface.
How to decide
Compare the modeling language, analytical methods, interface needs and audience. Both can support system exploration; the right fit depends on which details need to be modeled and how the results will be reviewed.
