Pricing FAQ
How does the free trial work?
Install the npm package and start building — no credit card required. The trial unlocks every feature for 30 days so you can fully evaluate the library. When you're ready, add a paid license key and keep the features you need.
What happens after the trial expires?
The chart stops drawing the chart body and shows a "License expired" prompt over the canvas. Your data, configuration and drawings are preserved — add a license key and everything comes back instantly.
How does domain licensing work?
Your license key is locked to specific domain(s) — see the feature comparison above for how many each plan includes. localhost is always allowed for development.
Can I use it in a mobile app?
Plans that list mobile support work with React Native, Flutter and Capacitor. The license is locked to your app's bundle ID instead of a domain.
How do I pay?
Checkout is handled by our secure payment provider with card payment (Visa & Mastercard). Click any plan to complete the purchase — your license key is issued to your account right after payment.
