Style: monochrome, oversized type, strict 12-col grid, visible outlines, sharp corners; cursor shows grid coordinates. Hero: stark headline, one-line value prop, two CTAs (“Start free”, “Docs”), background = live terminal demo typing a sample API call. Proof: SVG logo wall + light/dark invert toggle. Features: 3 code-snippet cards with tabs (JS/Python/cURL), copy-to-clipboard + tooltip. Pricing: 3-tier table with sticky header, CTAs open signup modal. Footer: keyboard-navigable site map + social links; only SVGs; responsive & fast.
Make it yours. Change "a brutalist developer platform landing page" to your own product, and the style line ("monochrome, oversized type, strict 12-col grid, visible outlines, sharp corners") to another look. Keep the section lines (Hero, Proof, Features, Pricing, Footer) and rewrite what goes in each.
Brutalist landing page for an API platform
A monochrome landing page for GRIDFORGE, a made-up API platform: oversized type, visible grid outlines, a cursor that reports grid coordinates, and a terminal typing an API call behind the hero. One of OpenAI's GPT-5.2 examples, made from one prompt.
“generated entirely in a single GPT-5 or GPT-5.2 prompt, without writing any code by hand”
How it was made
OpenAI's README says every demo in the collection was generated from a single GPT-5 or GPT-5.2 prompt with no code written by hand, and the gallery calls each one the zero-shot prompt that created the code. It doesn't say which tool ran it; the README suggests Codex CLI or ChatGPT. The same prompt run on GPT-5 is also in the gallery.

Look notesby Reference
A white, wireframe-like page for GRIDFORGE where every section sits in thin black outlines on a faint grid, from the hero headline down to a pricing table and a boxed footer site map.
- Color
- White with pale grey grid lines, black type and outlines; the only fills are black buttons and black tab chips.
- Type
- Heavy all-caps grotesque headlines ("SHIP AN API THAT FEELS LIKE A TERMINAL.", "THREE PRIMITIVES. NO MYSTERY."), small monospace labels and code, and a tiny grid-coordinate readout in the lower right corner.
- Framing
- 16:10. A left-aligned hero with a boxed "Brutalist contract" checklist at top right, then full-width bands split by rules: a two-row wall of outlined logo boxes, three code cards side by side, a three-column table, and a footer of outlined boxes.
- Structure
- Hero with Start free and Docs buttons over a latency strip, the "Used in places that hate surprises" logo wall with an invert toggle, code cards for Events, Auth, and Edge KV with JS, Python, and cURL tabs, the "Hard limits. Sticky header. No footnotes." pricing table, and the footer site map with social links.
