About

What is StateSmith?

StateSmith is a cross-platform, free/open-source tool designed for generating state machines in various programming languages. It creates human-readable code with zero dependencies, making it highly suitable for diverse applications ranging from tiny bare metal microcontrollers to video games, apps, and web platforms. A key differentiator is its avoidance of dynamic memory allocations, which is crucial for safety and performance-critical embedded systems. StateSmith ensures the diagram is always accurate by generating fully working code directly from the documentation, eliminating the common problem of manual synchronization between code and diagrams. The tool boasts a strong suite of over 730 integration tests that verify behavior across all supported languages, providing confidence in its reliability and allowing for refactoring without breaking specified behavior.
