Question 1

Is diCharts a drop-in replacement for TradingView?

Accepted Answer

Not exactly. TradingView is a hosted iframe widget with its own data, indicators, and social features. diCharts is a self-hosted library that gives you full control of rendering, data, and branding. You bring your own data and deploy it on your servers. If you need TradingView's social features or 100+ built-in indicators, diCharts isn't the right fit — but if you need performance, data ownership, and white-label branding, it is.

Question 2

What does "WebGPU rendering" actually mean for my users?

Accepted Answer

WebGPU is a modern browser API that gives JavaScript direct access to the GPU. diCharts uses it to render candlestick charts with GPU-accelerated geometry batching, which means 100K+ candles at 60fps with no frame drops. For your users, charts feel instant — zooming, panning, and real-time updates are buttery smooth even on large datasets.

Question 3

How does diCharts pricing compare to TradingView and HighCharts?

Accepted Answer

TradingView charges per-view fees that scale with your traffic. HighCharts uses per-developer licensing with complex tiers. diCharts uses straightforward pricing: the Community Edition is free and MIT-licensed for open-source use, and commercial licences are a flat fee with no per-view or per-seat charges.

Question 4

Can I migrate from Lightweight Charts to diCharts?

Accepted Answer

Yes. diCharts supports the same OHLC data format and similar API patterns. The main changes are switching from Canvas2D to WebGPU rendering (which is automatic), adding built-in indicators instead of DIY calculations, and using the built-in streaming engine instead of manual data updates. Most migrations take a few hours.

Question 5

Does diCharts support the same indicators as TradingView?

Accepted Answer

Not yet. TradingView offers 100+ indicators through its hosted platform. diCharts currently ships 5 built-in indicators (SMA, EMA, Bollinger Bands, RSI, MACD) with more being added. The key difference is that diCharts indicators run client-side on your data — nothing is sent to external servers.
