Machinations vs GoldSim
Machinations puts an economy’s or system’s rules in one shared diagram that a team can inspect, Play interactively and test with repeated Forecasts during the design conversation.
Machinations and GoldSim at a glance
GoldSim and Machinations both represent complex systems visually, but they emphasize different analysis workflows. GoldSim highlights dynamic simulation and quantitative uncertainty; Machinations makes system rules and resource flows directly explorable.

Who should choose which
Where Machinations may fit
Consider Machinations when a team needs a shared diagram of an economy or other system, wants to inspect its resource rules, and values interactive Play and repeated Forecasts as part of the design conversation. Monte Carlo Forecasts, which Play a model many times to show the range of possible outcomes, run on Machinations’ cloud servers.
Where GoldSim may fit
Consider GoldSim when you need hierarchical dynamic models, Monte Carlo treatment of uncertainty, discrete events superimposed on continuously varying behavior, or specialized risk and engineering analyses.
How to decide
Match the tool to the model’s required detail, uncertainty treatment, deployment and validation approach. A scenario result is only as useful as the assumptions, evidence and boundaries behind it. In the table above, Cloud execution for Machinations means that its Monte Carlo Forecasts run on its cloud servers.
