Tectogeny

A first build of a website, different on every seed

A Stylogeny style becomes a guideline (what the style leaves open, and how strongly it leans), and a seed rolls one site inside it on a Topogeny page. The same seed always rebuilds the same site, another seed gives another site, and contrast, sizes, focus and reflow are floors no roll can move.

Works no.

Tectogeny’s compare view: three seeded rolls of a Bauhaus restaurant page side by side, each with its typefaces and the choices it made.

What is inside

  • Compare six seeds side by side, or open one and read why each decision went as it did
  • Any Topogeny part, kit or layout style dressed in a style, with Morphogeny’s patterns or historical works as pictures
  • A build is a folder you own: page, tokens, fonts, recipe, and a contract an AI builds further pages from

How it is built

TypeScript in Node, with a plain one-page app and an MCP server. The floors are checked in real browsers at five widths; no model or critic judges the page.

It takes a Stylogeny style and a Topogeny page, and asks Morphogeny for its pictures.
