Machinations vs Python
Machinations makes the economy or system you are designing visible: resources, rules and feedback in one diagram that economists, designers and engineers can inspect, Play and question together.
Machinations and Python at a glance
Python is a general-purpose programming language, so a model written in it is exactly as flexible as the code you write. Machinations is a visual modeling tool for resource systems. Both can explore how a system behaves; they differ in who can read the model and how much you build yourself.
Side by side
| Decision factor | Machinations | Python |
|---|---|---|
| Modeling workflow | Visual resource-flow diagrams where nodes and connections make system structure and relationships explorable. | Code: you choose the data structures, the update rules and the libraries, and write the loop that advances the model. |
| A strong fit when | You want a team to understand how resources, incentives and feedback shape an economy or complex system, using a model they can build, Play and discuss together. | You need custom logic, large data sets, statistics or machine learning, or a model that lives inside a larger software project. |
| Explore model behavior | Step, Interactive Play and Forecasts let teams inspect a diagram and compare repeated Plays without writing a loop. | Run a script as often as you like, loop over parameters, and plot results with libraries such as Matplotlib; the experiment design is yours to write. |
| Who can read the model | Anyone who can open the diagram: the structure is drawn, and a Play shows its behavior. | Anyone who reads Python; the structure is in the code, and its clarity depends on how it is written and documented. |
| AI and integrations | An AI agent can build a diagram from a plain-language prompt or from uploaded files, including a .py script. Claude, ChatGPT and other AI tools can build, edit and Play diagrams through the Machinations MCP connector, and Google Sheets import/export depends on the plan. | Python has a very large ecosystem of libraries for data, statistics, machine learning and simulation, and connects to almost any service. |
| Pricing and licensing | See current Machinations plans on the pricing page; plan terms and Credit allowances can change. | Python is free, open-source software. The libraries you add each carry their own licenses; confirm them before you rely on one. |

Who should choose which
Where Machinations may fit
Choose Machinations when the model must be read and challenged by people who do not write code, and the question is how resources, rules and feedback shape an economy. The diagram is the model, and an uploaded .py script can be read by the AI to build a starting diagram from logic you already have. Monte Carlo Forecasts, which Play a model many times to show the range of possible outcomes, run on Machinations’ cloud servers.
Where Python may fit
Choose Python when the model is better expressed as code: custom logic, large data sets, statistics and machine learning, repeatable experiments kept in a version-controlled repository, or a simulation library such as SimPy for discrete-event work or Mesa for agent-based work.
How to decide
Settle who needs to read the model. If only the people who write it do, code is a fine home. If designers, economists or stakeholders must inspect and change it, a diagram they can open shortens the loop. Many teams do both: the diagram explores the design, and Python checks it against data. Validate parameters and boundaries against the real system whichever tool you use.
