AI site builder — bring your own key

Every AI site builder generates a website. This one refuses to generate a bad one.

Multipage sites from a single prompt — planned, designed against eleven anti-pattern gates, animated, with working forms and SEO compiled into static HTML. Publish to your own cloud. Use your own API key.

Design Discipline

Eleven things it will not do

Most generators optimise for plausible. Plausible is where the tells live — emoji standing in for icons, italic headings, invented statistics, a fake browser frame around a screenshot. StackingGrapes ships a written list of anti-patterns and checks every generated page against it. The list is code, not a prompt.

What ships

  • Icons drawn on one grid, one stroke weight
  • Headings that get emphasis from weight, not slant
  • Claims you could check against the repository
  • Screenshots shown bare, on a shadowed plane
  • Invented metrics content.invented-metrics
  • Italic headings typography.italic-headings
  • Split section headings structure.split-section-heading
  • Simulated device chrome decoration.simulated-device-chrome
  • Emoji as icons icons.emoji-substitution
  • Ordinal eyebrows structure.ordinal-eyebrows
  • Unbounded image grid tracks layout.unbounded-image-grid-track
  • Missing focus-visible a11y.missing-focus-visible
  • Indiscriminate transitions motion.indiscriminate-transition
  • Layout-property animation motion.layout-property-animation
  • Root overflow clipping layout.root-overflow-clipping

This page passes all eleven. Scroll back and look for a fake browser frame — there isn't one.

Full Site

It plans the site before it writes a page

A prompt becomes a plan: how many pages, what each one is for, which sections in which order. Then every page is generated against the same design system and the same structural archetypes — so the nav, the footer, the hero and the section heads agree across the whole site instead of drifting page by page.

82 design-system presets across 9 industry groups seed the look; deterministic archetype rotation keeps sections from repeating.

Clone & Screen2Code

Start from a URL. Or a screenshot.

Point it at a site and it captures a full-page screenshot, reads it with a vision model, and returns structured design DNA — category, design context, UI kit spec. That DNA feeds generation. You get a site built on the same design logic, not a copy of someone's markup.

Captured

Extracted DNA

{
  "site_category": "saas_tech",
  "design_context": {
    "mood": "confident, technical",
    "density": "airy",
    "palette_seed": "#6366F1"
  },
  "ui_kit_spec": {
    "nav": "slim-fixed",
    "hero": "headline-left",
    "corner_radius": "12px"
  }
}

Design System Studio

One source for colour, type and shape

Colour, typography and shape live in one token layer. Change the system and every page follows — because no section carries a private copy of a brand colour. 82 presets across 9 industry groups, or generate one from a description.

Motion & Media

Motion that behaves

Ten scroll and hover recipes. They animate transform and opacity only, they honour reduced-motion, and they are the same modules running on this page right now.

fade-in
reveal-up
reveal-left
scale-in
stagger-reveal
stagger-parts
soft-parallax running in the hero
scroll-progress
hover-lift
focus-emphasis

Generate the media too

Generate or replace any image on the site — Flux 2 Pro, Nano-Banana 2, Seedream 5 — or video with Kling 3 Pro, Seedance 2, and MiniMax H3, through fal. Bulk-generate every placeholder in one pass.

Stacking Forms

Static sites can't take submissions. Yours can.

A static export has no server. That is why the contact form on most generated sites goes nowhere. StackingGrapes gives every site a real form backend: managed forms built in the editor, rewritten at export to post to a hosted endpoint, with spam checks, domain allow-listing, rate limits, email notifications, signed webhooks and a submission inbox.

Classic forms work with JavaScript switched off; AJAX forms are progressively enhanced.

  1. form in editor
  2. static export
  3. POST /f/:key
  4. spam & domain checks
  5. stored
  6. email + signed webhook
  7. inbox

SEO & Blog

Search-ready on export

Per-page title, description, canonical, robots, Open Graph and Twitter cards, with site-wide defaults and AI generation per field — derived automatically when you leave them alone.

A native static blog ships with it: posts move through draft, review, ready, published and archived, and render into the same static output.

FAQ

Questions

Do I need an API key to start?

Yes — a free OpenRouter key is enough to generate your first site. StackingGrapes never resells inference.

What happens to my sites if I stop paying?

Your exports are plain static HTML sitting in your own storage. They keep working. You lose the editor, not the site.

Are the forms really hosted?

Yes. The endpoint is ours; the site is yours. Submissions land in your inbox and your webhook.

Can it edit a site it didn't generate?

Yes — import via Screen2Code from a URL or a screenshot.

Is the generated HTML mine?

Yes. Portable static export, with no runtime dependency on us except forms, if you use them.
