Genspark Build — Preview

AI Website Builder that actually ships.

Tell the AI what you want. It writes the code in front of you, refreshes the live preview with every file, and in a few minutes you have a real site you can deploy.

Start from a preset:

How it feels to build

The whole workspace is the prompt

Chat on the left, live preview in the middle, files on the right. Type, watch it render, keep going.

Chat

A dark editorial portfolio for a freelance photographer. Five sections, warm typography.

Drafting `index.html`, `about.html`, `/assets/styles.css`. Adding a film-grain treatment on the hero…

Why Genspark Build

Not a generator that spits out a mockup.

This one writes real files, runs a live preview, and lets you ship the result.

Real code, not screenshots

HTML, CSS, JavaScript — yours to keep

Every page is a real file. Download it, edit it, pass it to an engineer. No proprietary editor, no export fee.

<section class="hero"> <h1>Stories in light.</h1></section>

Claude-powered

Claude Opus 4.7 under the hood

Claude plans the site, writes the files, and fixes its own mistakes when the preview looks off.

Multi-page

Whole sites, not one-pagers

Home, About, Work, Pricing, Contact. All generated together. Navigation stays in sync, and the design system carries across every page.

Live preview

Watch it render, file by file

The preview updates the moment a file is written. No build step to wait on. Hover states, animations, and responsive breakpoints all work live.

Deploy in one click

Ship to Cloudflare Pages

Hit Build it. Genspark drops the prototype into a real project, wires up Cloudflare Pages, and hands you a public URL.

Also apps

Websites today, mobile apps on the same canvas

Flip the target to app. The canvas switches to an iPhone frame and Build it hands you a Flutter project with Dart code.

Start from a proven prompt

What people are building

These are the actual starter prompts inside Genspark Build. Click one and the AI takes it from there.

From prompt to production

Four steps, no build pipeline, no learning curve.

Describe

Type what you want in one sentence, or in a paragraph. If something is ambiguous, the AI asks instead of guessing.

Preview

Files appear in the tree and the preview renders them. You can hover-test animations and responsive breakpoints as the code gets written.

Refine

Select any element on the canvas and edit it inline, or ask the AI to rework a section. Style changes carry across every page.

Ship

Hit Build it. The prototype becomes a full Cloudflare Pages project with a public URL you can share the same minute.

Two targets, one canvas

Websites today. Or switch the target and the same prompt ships a mobile app.

The canvas previews both targets — a browser on one, a phone frame on the other. Pick one and Build it gives you the matching project.

Target: Website

HTML / CSS / JS on Cloudflare Pages

Same-domain iframe so the preview matches production
Signed preview URLs — only people you share them with can open them
Ship to Cloudflare Pages via the Build it handoff

Target: App

Flutter project with a live iPhone preview

iPhone device-frame preview on the canvas
Real Dart and Flutter code, not a mockup
Hand off to a full Flutter project for iteration

Frequently Asked Questions

How does the AI website builder actually work?

You describe the site in the chat panel. Claude Opus 4.7 plans the pages and writes the code; the preview iframe renders each file as it lands. When you are happy, hit Build it and Genspark packages everything into a Cloudflare Pages project with a public URL. No local build tools required.

Is Genspark Build free?

You can try Genspark Build and preview a site for free. Ongoing generation and the Build it deploy step sit inside the Genspark Plus and Pro plans. There is no unlimited-free offer — each build costs real compute.

Is this an AI website builder or an AI website generator?

Both, really. Genspark Build generates the site from a prompt and then keeps building on the same files as you iterate. The old split between builder and generator stops mattering once the code is live in front of you.

Can I ship the website to my own domain?

Yes. Build it creates a Cloudflare Pages deployment with a public URL out of the box, and you can point a custom domain at that deployment. If you prefer to host elsewhere, download the project — standard web code you can serve from anywhere.

What kinds of websites can I build?

Landing pages, SaaS homepages, portfolios, pricing pages, dashboards, signup flows, decks, onboarding screens. The starter prompts above aren't mockups — Genspark Build generates each one end to end.

Can it also build a mobile app?

Yes. Flip the target from website to app. The canvas switches to an iPhone frame, the AI writes Dart and Flutter code, and Build it hands you a full Flutter project instead of a Cloudflare Pages one.

Do I own the code the AI writes?

Yes. Download it, edit it, fork it, hand it to an engineer. There is no proprietary editor holding the code and no export fee.

How is this different from Wix, Squarespace, or other website builders?

Traditional builders give you blocks to drag around. Genspark Build gives you a chat box. You describe the site, the AI writes the code, and you iterate by typing. What comes out is real code that belongs to you.
