Machinations vs Lua
Machinations makes the economy or system you are designing visible: resources, rules and feedback in one diagram that designers, economists and engineers can inspect, Play and question before it is built.
Machinations and Lua at a glance
Lua is a lightweight scripting language that many games and tools embed to run their rules. Machinations is a visual tool for designing and testing those rules first. A Lua script is how an economy is built into a game; a Machinations diagram is how a team works out what it should do.
Side by side
| Decision factor | Machinations | Lua |
|---|---|---|
| Modeling workflow | Visual resource-flow diagrams where nodes and connections make system structure and relationships explorable. | Scripts and data tables that an engine reads; the model is whatever the code and the data define. |
| A strong fit when | You are designing an economy and want designers, economists and engineers to inspect, Play and discuss it before it is built. | You are implementing rules inside a game or tool that embeds Lua, or writing a script to test a rule in that engine. |
| Explore model behavior | Step, Interactive Play and Forecasts let teams inspect a diagram and compare repeated Plays without an engine. | You run the script in its host, usually the game or a test harness, and read what you chose to log or display. |
| Who can read the model | Anyone who can open the diagram, with no code to follow. | Anyone who reads Lua and knows the host’s conventions. |
| AI and integrations | An AI agent can build a diagram from a plain-language prompt or from uploaded files, including a .lua 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. | Lua is embedded in many engines and tools, which expose their own functions to scripts; what is available depends on the host. |
| Pricing and licensing | See current Machinations plans on the pricing page; plan terms and Credit allowances can change. | Lua is free software under the MIT license. Engines and tools that embed it have their own terms. |

Who should choose which
Where Machinations may fit
Choose Machinations when the economy is still being designed and designers, economists and engineers need to see and challenge it together. Play and Forecast show how the rules behave over many steps before anyone writes the final code, and an uploaded .lua script can be read by the AI to build a starting diagram from rules that already exist. Monte Carlo Forecasts, which Play a model many times to show the range of possible outcomes, run on Machinations’ cloud servers.
Where Lua may fit
Choose Lua when you are implementing the economy: the item tables, drop rules and pricing logic that ship with the game, or a quick script that tests a rule inside an engine that embeds Lua. It is small and fast to embed, which is why many game engines and tools use it for scripting.
How to decide
Decide which stage you are in. While the design is open, a diagram that everyone can read and Play is the faster way to find a problem. Once the design is settled, the script is what ships. Teams often draw first, then write the Lua. Validate parameters and boundaries against the real system whichever tool you use.
