Publication-ready charts for every surface.

Create in the browser, from code, in Figma, or with an AI agent. The same chart definition renders as PNG or SVG, editable Figma assets, and interactive embeds.

The web editor is the no-code way to create the shared definition. Switch the type or theme and the chart rebuilds itself.

The full editor adds your data, labels, sizing, and a link that renders anywhere.

Your chart is JSON.

The editor writes the definition for you. You can also write it directly or ask an agent – the same small config produces the same chart everywhere.

Adapt any theme to your brand with themeOverrides.

Free to make. Priced by renders.

No per-chart fees, no view counts. Making and editing costs nothing – the only metered thing is a fresh render, and the cache keeps those rare.

250

renders a month, free

Before you even make an account. A free account raises the ceiling and adds saved charts and live embeds.

$0

for ten views or ten million

Charts are served from a global cache. Millions of views trigger just a handful of renders a day.

$29 flat

for Pro, seats included

A bigger render ceiling for the whole team. The meter counts renders, not people, not views.

The fine print is short: see plans and limits.

The difference is in the defaults.

Real data, default settings – nothing here was styled by hand.
