béton brut means "raw concrete" in French, and in architecture that's what brutalism is. I'd say only sites that look like they use the default style of HTML with no CSS on Netscape 1.x could be called "brutalist"...
E.g. https://stallman.org
IMO the design is more "Windows 3.1 Hot Dog Stand Theme" https://blog.codinghorror.com/a-tribute-to-the-windows-31-ho... combined with MS WordArt...
> Neobrutalism is a mix of regular brutalism in web design and more modern typography, illustration, and animation standards. Neobrutalism refuses the usual components of UX-UI design and embraces uncomfortable design elements, and it is more fearless to use distinctive color palettes.
neobrutalism should have sharp edges, very vibrant saturated colors, and virtually none of these flowery spiral shapes. (neo)brutalism is forcing a square peg in a round hole with a hammer, and leaving it like that on purpose, because the raw swedge is the aethetic.
If I create something called Neo-Cuisine, you'd expect the result to be edible. If I see something calling itself "Neo-Brutalist Architecture", I'd expect it to look like Brutalism, or have some hallmark of the style. e.g. raw, but a different material new to the time period).
As far as web design, there's nothing "raw" about 100s of dependencies and animated charts and rounded rects and opinionated fonts and the rest of the this pastiche in "64 components, charts and star shapes for React and Tailwind v4. Built on shadcn/ui and Base UI." This is just Corporate Memphis + dialog aesthetics[0]
Broadly, it's a move away from flat, low contrast Material-type UIs and also away from the 'gradients and curves' AI-era designs and back into something that's more like the early web.
