Doesn't work on my Android phone because no GPU (but I have webgl is that not enough?)

You have a GPU, and you have WebGL but what's missing is WebGPU support, the latest way of doing GPU-stuff in browsers.

No Firefox support? It has had WebGPU support since version 141. Even when I turn on dom.webgpu.enabled, I still get "WebGPU is disabled by blocklist" even though your domain is not in the blocklist, and even if I turn on gfx.webgpu.ignore-blocklist.

Works for me with 146.0.1 (Linux) and having dom.webgpu.enabled set to true.

Which platform? I think FF has only shipped WebGPU on Windows so far.

Wa, this is smooth, man. This is so cool. This is really sexy and cool, the examples page ( https://chartgpu.github.io/ChartGPU/examples/index.html ) has many good. I hope you have a way to monetize/productize this, because this has three.js potential. I love this. Keep goin! And make it safe (a way to fund, don't overextend via OSS). Good luck, bud. Also, you are a master of naming. ChartGPU is a great name, lol!

Thanks! The name was honestly just "what does this do" + "how does it do it" haha. Interesting you mention three.js - there's definitely overlap in the WebGPU graphics space. My focus is specifically on 2D data visualization (time series, financial charts, dashboards), but I could see the rendering patterns being useful elsewhere. On sustainability - still figuring that out. For now it's a passion project, but I've t…

Have you thought about leaning into some of the fintech space? They'd happily pay for the sorts of features they need to stream financial data (which is usually bazillions of data points) and graph it efficiently.

Off the top of my head, look into Order Book Heatmaps, 3D Volatility Surfaces, Footprint Charts/Volatility deltas. Integrating drawing tools like Fibonacci Retracements, Gann Fans etc. It would make it very attractive to people willing to pay.

Cool to see that this project started 5 days ago! Unfortunately, I can not make it work on my system (Ubuntu, chrome, WebGPU enabled as described in the documentation). On the other hand, It works on my Android phone...

Funny enough, I am doing something very similar: a C++ portable (Windows, Linux MacOS) charting library, that also compile to WASM and runs in the browser...

I am still at day 2, so see you in 3 days, I guess!

This looks great. Quick feedback, scrollbars don't work well on my mac mini M1. The bar seems to move twice as fast as the mouse.

Thanks for the bug report! That's the data zoom slider - sounds like a momentum/inertia scrolling issue on macOS. Which demo were you on? (million-points, live-streaming, or sampling?) I'll test on M1 today and get a fix out. Really appreciate you taking the time to try it :)

I also noticed it. On million-points. MacBook Pro M2 on Firefox Nightly 148.0a1 (2026-01-09) (aarch64)
