Show HN: Shader Lab, like Photoshop but for shaders

Nice interface -- I made something similar but for a specific game (Binding of Isaac) because it has a specific way of implementing shaders for mods. https://sublimnl.github.io/IsaacShaderStudio/

A while ago (8 years in fact) I wanted to make something like this. I made a slightly half-assed React library that used twgl to overlay a shader on an element on a page (or a canvas for some effects). One thing I had was measuring where an element was on the page and then using absolute positioning to put a canvas over it so effects could expand beyond the confines of the element. I still think that has potential for some fun things but browsers aren't really fast enough to keep it in the right place with scrolling so it never works properly. https://react-neon.ooer.com/ + https://github.com/onion2k/react-neon

These new libraries are much better than anything I came up with.

Doesn't seem to load for me except the side windows. Firefox/Linux. HN hug of death?

The design language screams vibe coded to me.

looks like a slopfork of the fairly new https://shaders.com - frustrating for them!

I started https://unicorn.studio (first of its kind for layer based shader composition) back in 2020! Thankful that I did because I actually had to learn GLSL the hard way. Not sure that I would have bothered if building it today.

Bookmarking for later. Really curious to explore this when the brain cells are back online in the AM.

Is this lacking FPS caps or is something very unoptimized? Everything is smooth, but this website makes my computer run super hot and laptop fans spin up like nothing else does, even other shaders. (recent Chrome, recent MBP)

That is so laggy, but the UI looks really cool!
