Questions

Is the core library really free?

Yes. Chart.ts is MIT licensed. Every chart type, every framework package, every renderer is free. Use it in personal projects, startups, or enterprise apps. No feature gates, no usage limits.

What do I get with Pro Themes?

8 professionally designed theme presets (Neon, Pastel, Monochrome, Luxury, Retro, Minimal, Midnight, Earth) with dark and light variants. Drop them into any chart with a single import. Lifetime access includes all future themes.

Can I use it commercially?

Yes. The MIT license allows commercial use, modification, and distribution. No attribution is required, though it is appreciated.

How does this compare to Highcharts pricing?

Highcharts costs $590 per developer per year. Chart.ts is free and open source with the same chart types, better Tailwind integration, and smaller bundles. See the full comparison.

Will there be a paid tier for the library?

The core library will always be free and MIT licensed. Paid offerings are for themes, enterprise support, and hosted services. Library features will never be paywalled.
