How it works

One API. The whole lifecycle of a website.

AgentBuild is where an agent operates a business web presence: templates, content, design, build, deploy, DNS, email, forms, SEO. One surface, one call pattern, one bill, whichever AI the human uses.

What happens when your agent calls the API

Template + content

Your agent picks a template from our curated library (15 section types, ~25 variants), fills in the content, picks a theme preset, and the site takes shape as structured JSON, never HTML.

Validate, then build

The platform validates every field before the build starts: broken links, missing required content, and invalid embed URLs are caught in milliseconds. A clean build generates static HTML for every page.

Deploy to the edge

Static files go to Cloudflare Pages, served from every CDN edge location. Every page is a cached file fetch. No runtime database, no cold starts, no autoscaling bill.

Domain + email

Your agent connects a domain (registrar-agnostic), configures DNS, and sets up email routing so hello@yourdomain.com lands in the inbox you already use. One API call each.

One call

From zero to deployed.

Your agent passes the business facts, a design preset, and the page structure. AgentBuild builds and deploys a preview site. From there, updates are another call to the same API.

site_build — one MCP tool call
site_build({
  slug: "frankies-bakery",
  business_name: "Frankie's Bakery",
  business_type: "bakery",
  preset: "warm-artisanal",
  description:
    "Family bakery with a sourdough focus, " +
    "baking fresh since 1998.",
  pages: [
    { slug: "home", title: "Home",
      sections: [ /* hero, features, ... */ ] },
  ],
  discovery_notes:
    "Hours + menu are placeholders pending owner input.",
})

Why static, why edge.

We run the same architecture Webflow uses to serve millions of sites. Static HTML, global CDN, zero compute per pageview. A stack of small, real advantages that add up.

  • Zero compute per pageview. Static files from CDN. A viral moment costs nothing.
  • Sub-30ms global TTFB. Cached at every CF POP. Singapore, São Paulo, Reykjavík: same speed.
  • Core Web Vitals boost. Static HTML scores near-perfect on LCP, TTFB, CLS.
  • Build-time validation. Typos, broken links, and schema errors fail the build and never reach a visitor.
  • Resilience. No database in the request path. The site keeps serving during infrastructure incidents.
  • No rate limits at scale. CDN handles whatever traffic the site gets. No Worker quotas, no cold starts, no autoscaling bills.
  • Lower attack surface. No runtime query layer, no admin UI, no plugin system.
