Highcharts is a JavaScript charting library for interactive charts, maps and Gantt timelines, free for non-commercial use and from $366 per developer seat per year commercially.
A commercial project needs at least Highcharts Core, $366 per developer seat per year.
About
In practice. What you can do with Highcharts.
Highcharts is a configurable JavaScript charting library covering standard charts (Core), financial and timeline charts (Stock), maps (Maps) and Gantt/project timelines (Gantt), plus a broader suite with Highcharts Grid for tables and Highcharts Dashboards for KPI dashboards.
It's free only for personal, school, charitable and non-profit non-commercial projects; any commercial product needs a paid license billed per developer seat per year, starting at $366/seat/year for Core (Stock, Maps and Gantt add $366, $128 and $73 per seat on top; Dashboards and Grid Pro are separate products at $264 and $316 per seat/year). A one-time 'Advantage Plus' option can be added for perpetual access to the version held when the subscription ends.

Pros and cons. What Highcharts does well, and what to expect.
Pros
Covers standard, financial, map and Gantt charts in one consistent library instead of combining several tools.
Free to use for personal, school, charitable and non-profit non-commercial projects.
Cons
Any commercial use requires a paid license; there's no commercial free tier.
Per-developer licensing means team costs grow directly with headcount.
When it makes sense. Keep Highcharts, or challenge it?
Keep if
You need a broad, configurable charting library (standard, financial, maps, Gantt) in one commercial product and can budget per-developer licensing.
Highcharts becomes worthwhile when
+You use it at least once a week
+The monthly cost ($30.50) is small next to the time it saves you
Challenge if
You're building a free, open-source or non-commercial project, since the free tier doesn't cover commercial use.
Highcharts becomes too expensive when
−You use it less than once a month
−chartjs (free) already covers the essentials for occasional use
Our verdict. What to know about Highcharts.
Why this verdict
Average
Added value
Per-developer-seat annual licensing (366 USD/seat/year for Core) scales directly with team size rather than a flat product fee, which raises cost for larger teams.
Simplicity
Ships ready-made chart types (standard, financial, maps, Gantt) rather than requiring charts to be built from a lower-level drawing library.
Fit for purpose
Delivers the advertised chart types and the extended Grid/Dashboards suite without needing a separate library for maps or Gantt timelines.
Performance
Covers standard, financial, map and Gantt/project charts plus tabular and dashboard products in one suite, more than a single-purpose charting library.
Reversibility
Neutral score: data and chart-configuration portability if switching away from Highcharts is not covered by the collected sources.
