Charts as infrastructure

Real-time charts,
one line of code.

The embeddable charting layer for every product that touches markets — streaming data, 60fps rendering and a fully themeable SDK.

$ npm i @chartx/sdk
chartx.io
The problem

Every product that touches markets rebuilds the same chart.

Months of engineering

A production-grade chart — pan, zoom, indicators, drawing — is a quarter of work before a single customer sees it.

60fps streaming is brutal

Coalescing thousands of ticks per second without dropping frames defeats most teams — and their users feel every stutter.

Then you maintain it forever

New chart types, browser quirks, theming, compliance — the burden never ends, and it isn’t your core product.

73% of fintech teams build charting in-house — and most call it their biggest distraction.

The solution

Charts as infrastructure.

Not a library you babysit — a managed stack you call. ChartX delivers markets-grade charts the way Stripe delivers payments.

Data plane

Connect any WebSocket or use our managed market feed. Coalesced, buffered, backfilled.

Edge render engine

Charts rendered close to every user across 30+ regions at a steady 60fps.

Drop-in SDK

One typed component for React, Vue, Svelte & vanilla. Themeable to the pixel.

<ChartX symbol="AAPL" feed={feed} theme={brand} />

Why now

The infrastructure layer is missing.

$240B
embedded-finance market by 2030, pulling markets data into every app.
150M+
retail investors now expect a live chart in everything they touch.
Real-time
is the new default — static, delayed data no longer ships.

Stripe did it for payments. Plaid did it for data. ChartX does it for charts.
