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.

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.
