## What it is

SciChart.js renders through a WebAssembly engine with WebGL acceleration rather than through the
DOM or a 2D canvas context, which is the reason to consider it and the reason it is heavy. The
vendor claims real-time rendering of up to 100 million points at 60 FPS; that is a marketing
figure with no published method behind it, and nobody has run it here.

For finance it gives you the primitives — `FastCandlestickRenderableSeries`,
`FastOhlcRenderableSeries`, an `OhlcDataSeries`, multi-pane surfaces with synchronised zoom and
cursors, and an annotations API covering lines, boxes, text, axis markers and arbitrary SVG. What
it does not give you is a single technical indicator or a single financial drawing tool. The
published 5.2.69 package has no MACD, no RSI, no Bollinger Bands, no Stochastic, no Ichimoku, no
Fibonacci and no pitchfork anywhere in its 1,484 files; the trading drawing tools and indicator
panels in the demos are example source you copy into your own project.

Version 5.2.69 went to npm on 8 September 2026, with a 6.0.0 alpha publishing almost daily
alongside it.

## Pricing

Per developer, billed upfront, in US dollars. The store is a tab per platform — Product Bundles
first and marked "best value", then JavaScript, WPF, iOS, macOS and Android as individual products
— and inside each tab the price is shown per month against a term selector that **defaults to
three years**. So the first number you see is the cheapest one on offer, not what a year costs.

On the JavaScript tab: **SciChart.js 2D is $1,349.66 per developer for a one-year term**, shown as
$84.35 a month over two years and $67.48 over three; the mechanism is a 50% discount on the second
year and a further 10% off a three-year total. Adding 3D takes the one-year rate to $1,765.26,
$110.33 a month over two years and $88.26 over three. A 90-day money-back guarantee and a
50%-off small-business discount, conditions attached, sit above the table on every tab.

Standard Licensing — what the JS-only products carry — covers up to five websites or applications
and up to 15,000 end users per licence, with runtime keys locked to domains you register in your
account. Advanced Licensing, which is what you need for non-domain-locked keys, OEM distribution,
more than five projects or more than 15,000 users, is sold only with the cross-platform Bundles:
**$194.73 a month for 2D Pro on a one-year term**, $146.04 over two years and $116.84 over three,
with 2D/3D Pro at $289.97 / $217.48 / $173.98 and 2D/3D Source at $385.21 / $288.91 / $231.13. The
bundles are also the only tier that carries the library source code, and they double the support
allowance from five to ten.

Two things in that table are worth knowing before you pick a tier. The free Community build lists
**all 3D charts, which the paid SciChart.js 2D licence does not** — starting to pay for the
cheapest commercial tier takes chart types away. And every JavaScript product, free or paid, is
marked *not* Advanced Licensing ready and *not* cleared for non-domain-locked web apps, so if your
product ships to customers' own domains, the JS-only SKUs are not the ones you want however
attractive the price is.

The Community Edition has been the default since version 3.2 — `npm install scichart` needs no
key and starts up free, and the bundle says so out loud: "Defaulting to SciChart Community
Edition." It is non-commercial only, watermarked at the bottom left, telemetered, unsupported, and
valid for six months from the *release* date of the version you shipped, after which the chart
draws an error instead.

## Data & coverage

None. SciChart.js draws arrays and knows nothing about symbols, sessions or exchanges. It is a
general scientific and financial renderer that happens to have candlesticks; a market-data feed is
entirely separate.

## Integrations

`scichart` on npm with no runtime dependencies, plus a jsDelivr build for a plain script tag. The
first-party React wrapper is `scichart-react`, MIT-licensed, still on 1.0.0 from August 2025 — a
year behind the library it wraps, with a 2.0.0 alpha published in September 2026 and no stable
release behind it yet. The WebAssembly binaries load as separate files,
which means a bundler config step — `scichart2d.wasm` alone is 1.28 MB, with `scichart2d.js` at
162 KB and the JavaScript entry point at 247 KB. SciChart also sells iOS, Android, macOS, WPF and
Avalonia libraries; licences are per product and are not interchangeable.

## Limitations

- **No indicators and no financial drawing tools in the library.** For a product marketed at
  trading platforms this is the single most expensive thing to discover late.
- **Domain-locked runtime keys.** Every production hostname is registered by hand in your account,
  and a key is regenerated after each change. Electron, on-premises installs and customer
  subdomains all push you to Advanced Licensing, which is Bundle-only.
- **The cheapest way to an unlocked key costs more than the JS product itself.** The 2D Pro bundle
  is $2,336.76 per developer for a one-year term, against $1,349.66 for SciChart.js 2D on its own —
  and the bundle is the only route to a key that is not locked to domains you register.
- **The free build expires.** Six months from the release date of the version you shipped, then an
  on-chart error. Fine for a hobby project you keep current; a trap for anything you deploy and
  forget.
- **Telemetry cannot be disabled on the free build,** and the deployment URL is part of what is
  sent. An air-gapped licence exists and is a sales conversation.
- **The pricing page is hostile to inspection.** It sits behind a bot check, the headline number
  is the three-year rate, and the store labels its own figures "representative pricing".

## Alternatives

[Highcharts Stock](https://stockmarketstack.com/tools/highcharts-stock) costs a fraction as much per seat and ships 48
indicators, at the price of SVG rendering rather than WebGL.
[TradingView Advanced Charts](https://stockmarketstack.com/tools/tradingview-advanced-charts) is free and arrives with
indicators and drawing tools, if you are a company shipping something free to its users.
[KLineChart](https://stockmarketstack.com/tools/klinechart) is Apache-2.0 with 27 indicators and no licence to manage.
[Lightweight Charts](https://stockmarketstack.com/tools/lightweight-charts) is the small free canvas option, with neither
indicators nor a WebGL engine.

## FAQ

### Is the free Community Edition usable in a commercial product?

No. It covers non-commercial applications, personal and academic projects, non-commercial open source, and a commercial evaluation of "a reasonable time period, for example 30-60 days". Commercial development and deployment need a paid per-developer licence.

### What are the catches in the Community Edition?

Four, all documented. A watermark at the bottom left that can be moved but not hidden or resized; console messages naming the edition; telemetry to Azure App Analytics carrying version, deployment URL, product code and licence type, which cannot be turned off; and an expiry. The library's own console message is the plainest statement of it — "The community license is valid for 6 months from the date the version in use was released." Rebuilding does not reset it; you have to move to a newer version and redeploy.

### Does SciChart.js ship technical indicators?

No. Searching all 1,484 files of the published 5.2.69 package for MACD, RSI, Bollinger, Stochastic, Ichimoku, Fibonacci or pitchfork returns nothing at all. The only analytical transforms are `XyMovingAverageFilter` and `XyLinearTrendFilter`, beside a ratio filter and per-series scale-offset filters. The indicators and trading drawing tools in the demos are example code you copy, not library modules you import.

### What happens when a paid subscription lapses?

Runtime keys are perpetual, so deployed applications keep working with the version they shipped. You lose new versions, support and test domains, and you need a fresh key only if you upgrade to a build released after your licence expired.
