Comparison
PolySim OS vs Simulink
Simulink is the gold standard for block-diagram modeling of dynamic systems — and it's superb. But it's a paid add-on on top of MATLAB, desktop-first, and heavy to get started. PolySim offers a browser-native visual block/graph editor plus hundreds of ready-to-run dynamic simulations, free, with nothing to install.

Feature comparison
| Feature | PolySim OS | Simulink |
|---|---|---|
| Block-diagram modeling | Yes (visual node graph) | Yes — industry standard |
| Runs in browser | Yes | Desktop |
| Cost | $0–$24/mo | MATLAB + Simulink licenses |
| Setup | Instant, in-browser | Install + license |
| Ready-made dynamic sims | Hundreds | You build them |
Where Simulink is strong
- • Deep, validated block library
- • Code generation for embedded targets
- • Industry adoption
Where PolySim wins
- • Expensive (add-on to MATLAB)
- • Desktop-bound
- • Steep onboarding
Choose Simulink for production control-system engineering and code generation; choose PolySim to model, teach, and explore dynamic systems free in the browser.
