NetLogo is a free, open-source modeling environment for simulating systems through interacting agents. It is used by educators, researchers, and students for...
Pros
- Free and open source
- Handles agent-based simulations that Loopy cannot represent
- Includes a large library of educational and research models
Cons
- Programming is required for many custom models
- Less direct for simple causal-loop diagrams
- Visual explanations take more setup than in Loopy
