Key facts

• Shop price fetched 2026-08-21: Highcharts Core 366 USD/seat. Internal license does not cover public websites; SaaS adds one External Application; OEM for customer-hosted / redistributed products. From 2026-08-21-autoresearch-best-frontend-visualization-libraries.
• Grokipedia’s “$176/year” figure contradicts the live shop and is treated as stale. Same source.
• Accessibility module: WCAG 2.2 guideline; keyboard navigation; screen readers; ARIA on chart elements. Without it, the chart is “interpreted as an image with the chart title in the aria-label.” Final compliance still sits with the integrator. Same source.
