Comparison
ORTEX Charts Compared With SciChart JS
SciChart JS is a WebGL charting library sold perpetually from $1,349 per developer with a year of updates, and it is the library to beat for very large point clouds rendered all at once. ORTEX Charts is Canvas 2D, is 76.9 KB gzip in one file for a full financial shell, first paints 100,000 bars in 32 ms, holds 60 Hz while panning and zooming at that size, and costs $590 per developer per year. SciChart wins on raw point count and cross-platform reach; ORTEX Charts wins on the financial furniture around the chart, on payload and on price.
Payload and timing figures were measured on 2026-09-04 in Chromium against the vendors' own published files and public demos; the feature review was carried out on 2026-09-03. Prices are the vendors' own published prices where they publish one, and are marked as unpublished where they do not. Where SciChart JS is better, this page says so.
Head to head
How the Two Line Up
Every cell is either a measurement or a published term. A cell that says "not measured" or "not published" is not an omission to be filled in later with a guess: it is the honest state of the evidence.
| What | ORTEX Charts | SciChart JS |
|---|---|---|
| A full shell | 76.9 KB gzip in one file | Not measured |
| Renderer | Canvas 2D | WebGL |
| Create to first paint, 100,000 bars | 32 ms | Not measured |
| Millions of points on screen at once | No | Yes |
| License | Subscription, per developer or per product | Perpetual, per developer, with a year of updates |
| Price | $590 per developer per year; $299 per product per month unbranded | From $1,349 per developer |
| Order flow | Footprint, volume profile, market profile, delta, cumulative delta | Not a focus of the product |
| Platforms | Browser only | Browser and native |
What Is SciChart JS Good At?
- WebGL rendering, which is the right tool for millions of points on screen at once without decimation.
- Scientific and engineering workloads: very large series, real-time instrumentation and dense scatter data.
- Cross-platform reach beyond the browser, which ORTEX Charts does not attempt.
- A perpetual license with a year of updates, which some procurement processes prefer to a subscription.
What Does SciChart JS Cost?
- From $1,349 per developer, perpetual with a year of updates, with a small-business discount.
- That is per developer and up front, against $590 per developer per year for ORTEX Charts, or $299 per product per month unbranded.
What Can SciChart JS Not Do?
- The financial furniture around the chart is thinner: the toolbar, the drawing layer, the order-flow studies and the replay controls a trading page expects are not the center of gravity of the product.
- No footprint bars, volume profile, market profile, delta or cumulative delta of the kind ORTEX Charts computes from aggressor volumes.
Where Does ORTEX Charts Win?
- Financial completeness: candles, panes, indicators, drawings, markers, order flow, replay, linked charts and draggable alerts in one library.
- Payload. A full shell in 76.9 KB gzip in one file.
- Price. $590 per developer per year, or $299 per product per month with the mark removed.
- Purchasing. A card payment and a key by email rather than a seat negotiation.
Where Does SciChart JS Still Win?
- WebGL. ORTEX Charts is Canvas 2D and does not render millions of points all on screen at once without decimation. If that is the workload, SciChart is the right choice today.
- Cross-platform reach outside the browser.
- Scientific chart types and the breadth of a general-purpose visualization suite.
Which One Should You Choose?
Choose SciChart JS when the workload is millions of points at 60 Hz, or when the same charts have to run outside the browser. Choose ORTEX Charts when the workload is financial: bars, indicators, drawings and order flow at the sizes a market data page actually carries, where Canvas 2D holds 60 Hz and the payload is two orders of magnitude smaller than a licensed drop.
Licensing and price
The Part That Decides the Shortlist
ORTEX Charts
Per developer for Team, per product for White-label, OEM by contract.
$590 per developer per year for Team; $299 per product per month for White-label; OEM as agreed.
Canvas 2D rather than WebGL: built for financial data sizes, not for ten-million-point scientific plots.
SciChart JS
Per developer, perpetual with a year of updates.
From $1,349 per developer, with a small-business discount.
Built for very large scientific point clouds; the financial furniture around the chart is thinner.
