How it works

One API. The whole lifecycle of a website.

AgentBuild is what your agent reaches for when a human asks for a website. Templates, content, design, build, deploy, DNS, email — one surface, one call pattern, one bill.

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, 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 a template name, a theme, and the content. AgentBuild returns a live URL. From there, updates are another call to the same API.

agent.ts

import { AgentBuild } from "@agentbuild/sdk";

const ab = new AgentBuild({ apiKey: process.env.AB_KEY });

const site = await ab.sites.create({
  slug: "frankies-bakery",
  template: "restaurant",
  theme: "warm-artisanal",
  content: {
    hero: { headline: "Frankie's Bakery",
            subhead: "Fresh bread since 1998." },
    menu: [ /* ... */ ],
    hours: { /* ... */ },
  },
});

// { url: "https://frankies-bakery.pages.dev",
//   build_id: "bld_01H...", status: "ready" }

Why static, why edge.

We run the same architecture Webflow uses to serve millions of sites. Static HTML, global CDN, zero compute per pageview. This is a stack of small, real advantages stacked into a site that's simply better than the CMS-backed alternatives.

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.
