ApexCharts vs Fathom Analytics

ApexCharts is shipping the v6 line at an unusual clip — ten releases since 20 July, spanning a plugin platform, a hybrid SVG/canvas renderer, and two new chart types. The core is still zero-dependency and SVG-first, and every release states that existing configs render unchanged. What is new is a commercial layer: an offline licence check now sits over seven premium modules and one chart type, while the free catalogue keeps expanding alongside it.

The commercialisation arc tightens one notch per release. 6.5.0 introduced licensing with a watermark and an explicit promise that no chart type would be gated; 6.6.0 gated one; 6.7.0 changed enforcement from accepting any valid key to requiring an entitled plan. Running underneath is a genuine engineering push — incremental updateSeries, canvas cell rendering, a numeric fast path for line and area — that makes the paid layer easier to justify. The pattern is a generous free core with the new authoring and analysis surface behind a key.

Expect more premium chart types following `unit`, since the gating machinery and trial-mode watermark are now built and proven. The shared key format across the apex* family suggests entitlement checks propagate to the sibling libraries next.
