Looks interesting, but to be honest I'm put off by the idea that you had AI rewrite someone's library and now you're using their name and brand to promote your $20-$100 per month tool based on their work.
Calling it Manim in the browser and using 3Blue1Brown's name is really misleading when you discover that it's none of those things and you're trying to charge for it.
This is a very bad misappropriation of someone else's work and fame for your personal gain.
I can only hope that this inspires some people to vibecode and equivalent service but make it open source and free to all.
Just to let you know that "Live preview" in Windows on ARM fails to start with the message below. Chrome and Edge, I did not test FF.
animg.app shadertoy.com and glsl.app are working fine at the same time.

Live preview couldn't start
Your browser supports WebGPU but no compatible GPU was available. Try updating your graphics drivers, enabling hardware acceleration, or using another device or browser.

I built the core of the animation engine, and I think our wording may have created the wrong impression about how it was developed.
For the use case we have, we needed a fast animation engine. The engine didn’t begin as a port or rewrite of Manim. We originally built it under a different name as a standalone Rust/WebGPU 3D animation engine for real-time AI tutoring. I spent roughly two months building the renderer and animation system from scratch.
Our original engine had a different interface, different defaults and produced different visual results. Only after the engine was already working did we decide to make part of its Python interface compatible with ManimCE. We did that because many users already know the Manim API, and coding models are already familiar with its classes and common animation patterns. We spent substantial time matching ManimCE’s visual behavior as closely as possible. We believe this compatibility layer makes adoption easier; yet the underlying renderer, scene system, and implementation are our own.
So describing this as vibe coding Manim in Rust and then closing the source is inaccurate. The browser editor, rendering, and video downloads are free. You are free to write code, render and download videos as much as you want. The paid features are the AI-powered functionality, which are priced to cover their cost to us.
We respect that some people would prefer it to be open-source, but choosing not to open-source an independently developed engine is different from taking an open-source project and repackaging it as proprietary software.
In that case you shouldn't call it Manim or "3Blue1Brown's animation engine". At best this has a partly Manim-compatible API, similar to how XY [1] has a partly Matplotlib-compatible API.
We are fully compatible with Manim CE. Our goal is 1:1 API compatibility, so people can continue using the API they already know.
We never intended to use 3Blue1Brown's name in a negative or misleading way. We simply wanted to communicate that we have made the Manim API created by 3Blue1Brown accessible in the browser with WebGPU, without requiring any installation.
This is very cool!! I'm also mesmerized about the opening animation that transforms the interface of the editor to a complete viewport state. For some reason is pretty laggy on Chrome (macbook air M1) but Firefox is super smooth. Besides that, awesome idea :)
Thank you! We simply mount the entire app inside the landing page, but rotate and scale it down. When the page opens, it smoothly animates into full screen using CSS transitions.
You can use the editor however you like without signing up. The examples are simply sample prompts for the AI, but you can paste in any Manim code to editor from ChatGPT or anywhere else, and the preview will render it instantly.
Downloading videos is completely free. Only the AI-powered features are behind the paywall, and there's a 7-day free trial.
That was also unclear to me, so +1 for more code examples. Also, it seems like maybe this doesn't work in Safari but there's not error message or anything. I was looking for a Run or Render button or something to get things to happen, until I gave up and tried Firefox.

This looks really bad.
Just FYI: We also have animation libraries like Motion Canvas that run in the browser using TS/JS: https://motion-canvas.io/ , which can also be used by AI agents with the right AI skills (e.g., https://github.com/VideoZero/skills )

Not open source...?
Worse: It's a paid tool.
They're trying to ride on top of 3Blue1Brown's code and fame for personal gain.

I was expecting to see the code too.
So you vibe ported manim to rust, kept it closed source, and you’re selling access to it with a monthly subscription? This isn’t satire?

You submitted this with the title “Manim (3Blue1Brown's animation engine) in the browser via WebGPU”
Being misleading is exactly what you intended to do.
Such bad faith here.. Rip off and then caught (inevitable, because most on HN likely love the original), then backpedal like crazy when called out
> So describing this as vibe coding Manim in Rust and then closing the source is inaccurate.
Your team submitted this with the title “Manim (3Blue1Brown's animation engine) in the browser via WebGPU”
If anyone is being misleading, it’s your team.
Maybe manim should not have used MIT as the license in the first place, since the license permits it.
Yo that homepage zoom from the app screenshot straight into the experience was SMOOTH.
Thank you :)
manim mcp is open source and works with your existing agent

All of the examples besides the first one that is itself underwhelming are behind a paywall. For all we know it could be pre-recorded. Hard pass.

Great work! This can go huge
