Agent-native site builder · no UI included

Say the site. Watch it ship.

Zero-UI has no editor, no canvas and no drag-and-drop. An AI agent writes the code, Zero-UI versions it, tests it in an isolated browser and publishes it to Cloudflare's edge.

001 / Build bay

Type a sentence. Get a website.

Describe the site you want. The agent drafts it, Zero-UI checks it in an isolated browser and publishes it to a real address you can open.

New / Learn Mode

Describe the course. Get the course.

Courses, workshops and guides from one sentence. The model writes the learning content; a tested template turns it into the page, so every build gets the same structure, interactions and accessibility checks.

Course microsite template: hero, outcomes and curriculum

Course microsite

A mini course on one page

Outcomes, a curriculum accordion, a live sample lesson, the instructor, FAQ and enrolment.

Module player template: outline sidebar, lesson view and progress

Module player

Self-paced modules

A course outline, one lesson per view, progress rings, resume and a printable certificate.

Workshop studio template: timed agenda and activity timers

Workshop studio

Timed workshops

An agenda with clock times, activity timers and a worksheet that gathers every reflection.

Signal lab template: Zero-UI style lesson console

Signal lab

Hands-on technical labs

The Zero-UI look: a module pipeline, a terminal-framed lesson console and a live progress receipt.

Field guide template: print-first participant and facilitator guide with an agenda ribbon

Field guide

Participant & facilitator guides

A print-first guide with an agenda ribbon, a participant or facilitator view, write-in pages and checklists.

Pick nothing. Learn Mode chooses the format and palette from your request.

002 / Pipeline

The interface is the agent.

Zero-UI exposes typed tools over the Model Context Protocol (MCP). Any capable agent can drive them. The page above runs exactly these steps.

  1. 001 / Intent

    One sentence in

    You describe the site in plain language. The model plans the structure, copy and interactions with no template picker.

    "build me a website that has…"
  2. 002 / Author

    Revision-checked source

    Every write is an atomic batch against an exact revision and file hash. No silent overwrites, and the full history is kept.

    apply_changes(expected_revision)
  3. 003 / Inspect

    An isolated browser looks first

    Generated code never runs on a host machine. A network-isolated Chromium renders it at desktop and mobile sizes and runs the declared checks.

    inspect_preview(steps, viewports)
  4. 004 / Publish

    Straight to the edge

    Release validation, Cloudflare Workers Static Assets hosting, a custom domain and live hash verification run as one durable call.

    publish_revision → get_publication
  5. 005 / Iterate

    Edit by asking

    Ask for a change. The same project, destination and URL are updated, and earlier revisions stay available for rollback.

    rollback_deployment(target)

003 / Ledger

From sentence to live URL.

0s

Wall-clock time for the recorded build: the model writing the site through OpenRouter, then Zero-UI checking it and verifying live hashes on the public domain.

Measured on 2026-11-06. Tokens and cost are what OpenRouter billed for this build; tool times are the measured Zero-UI MCP calls.

004 / Vibes

Dark mode, loud color.

Five palette directions for the showcase. Pick one and the whole page re-themes, including a hue shift on the generated hero image.

005 / Engine

A whole website for a quarter of a cent.

The recorded builds were written by GPT-6 Luna through OpenRouter, with Claude Haiku 5.5 and GLM 5.3 as fallbacks when a provider is busy. The hero art was made by a local FLUX model on Zero-UI's own GPU helper.

5,000
—per month with GPT-6 Luna

Per-build costs are what OpenRouter billed for test builds on 2026-11-06 using the Zero-UI system prompt (about 450–750 input and 4,000–8,000 output tokens). Six models were compared and all six outputs passed Zero-UI release validation. Prices change. The slider runs from 100 to 100,000 builds on a log scale; the total uses the primary model, and each card shows its own monthly cost.

006 / Signal

No UI.
All signal.

The builder is an API your agent already knows how to use. Connect Codex, Cursor or Claude Code to the Zero-UI MCP endpoint and start shipping.
