Pricing FAQ

Is PolySim really free?▾
Yes — all 390+ solvers run locally in your browser, free forever. You only pay for Pro features (saves, data import, exports, AI) or cloud compute.
Do I have to subscribe?▾
No. You can unlock any single solver for $2 or a full multi-solver workflow for $5 — one-time, no subscription. Pro just unlocks everything at once.
What's the difference between Pro and Team?▾
Pro is for one person. Team adds a shared workspace, pooled compute, admin controls, and seats for a lab, class, or firm.
Do students and educators get a discount?▾
Local use is free for everyone. Verified students and classrooms get additional discounts — just reach out.
Can I cancel anytime?▾
Yes. Cancel from your dashboard anytime; access continues to the end of the billing period.
How does this compare to MATLAB or COMSOL?▾
MATLAB toolboxes and COMSOL modules run into the thousands per year and need installs and licenses. PolySim starts free, runs in any browser, and tops out at flat, transparent plans.
