Free AI Website Builder
Free AI website builders are easy to find and hard to judge. This page explains what 'free' usually includes, how to evaluate the generation quality behind a signup form, and when paying for a plan actually makes sense.

Live workspace
Code, chat, and preview in one place.
The workspace is built for repeated product work, not disposable demos. Every generated file stays inspectable, every change is visible, and every follow-up can target the exact part of the app you care about.
01 · EDITOR
Generated code, ready to edit.
Every file BYOB writes stays visible and editable. Follow-ups target the exact lines you care about instead of regenerating from scratch.

Prompt to app
From first prompt to a workspace you can ship.
Start conversationally, approve the shape, let Tool Mode implement, then refine and deploy from the same workspace.
- 01 Describe the product Start with the outcome, audience, and any constraints. BYOB turns the idea into a practical build plan.
- 02 Shape the UX Review the proposed flows, screens, data needs, and visual direction before code starts moving.
- 03 Generate the app Tool Mode writes SvelteKit code, connects integrations, and keeps each change visible in preview.
- 04 Test and refine Ask for edits, roll back when needed, run checks, and keep the project editable instead of disposable.
- 05 Deploy Ship the finished app, connect domains, and keep iterating from the same workspace.
Agent and backend
Code with your agent, ship with a real backend.
Connect Codex, Claude Code, or Antigravity to your project, then store data and ship to production without leaving the workspace.

Loved by builders
Rated 4.9/5 by developers and founders using BYOB to move from idea to shipped product.
Built for shipping
The parts that usually slow you down are already here.
BYOB handles product planning, implementation, preview, testing, database work, and deployment from one focused interface, with coding-agent access and production analytics when you want to keep working from your own terminal.
This part is hands-on. The cards drift until you touch them. Drag to rearrange, or press and hold one to feel it push back.
Agent integrations
Give Codex, Claude Code, or Antigravity scoped access through BYOB CLI or Agent MCP. Your agent reads context, edits code, tests previews, and deploys from your terminal.
Git history and diffs
Every change lands as a commit. Inspect history, compare diffs, and see exactly what changed since the last deploy.
Inbox in every project
Every project ships with an inbox. Collect messages, leads, and feedback from your app without wiring a third party.
Email sending built in
Send magic links, OTP codes, and transactional mail from your own sender address. Resend-backed, no SMTP setup.
Google and magic-link login
Offer Continue with Google plus passwordless email codes. Sessions and callbacks are handled.
Custom domains and SSL
Point your domain at BYOB with guided DNS checks. Certificates are automatic.
Visual editing
Click any element in the live preview and describe the change. Copy, spacing, color, behavior.
AI testing agent
Run full-site or feature checks and get implementation-level feedback you can apply in one step.
Version rollback
Step between saved states or redeploy a known commit when an experiment goes sideways.
One-click deploy
Builds publish to production hosting in one step. Deploys can auto-save the project state first.
Deployment analytics
Worker traffic, errors, CPU timing, subrequests, and custom-domain status from the workspace.
Supabase aware
Connect Supabase and BYOB reads schemas, drafts migrations, and generates types that match your app.
Team collaboration
Invite people in and keep sessions coordinated so work never overwrites work.
- Vision inputs
- Voice coding
- Project templates
- SEO-ready output
- Context tracking

A free AI website builder lets you generate and preview a website from a prompt at no cost, usually with limits on custom domains, usage or team seats. BYOB's free starting point lets you test the generation and editing workflow before upgrading when you need a domain, more capacity or app features.
What 'free' typically includes
Most free tiers give you the generator and a preview, then withhold a custom domain or add an usage cap. That model is reasonable as long as you understand it up front. The useful question is whether you can produce and refine a complete draft without a paywall interrupting the work. With BYOB you can describe a site, review the generated pages and keep editing, so the free experience demonstrates the real workflow rather than a cut-down demo.
How to test the generation quality
A giveaway free tier hides weak output behind a friendly signup. To evaluate properly, pick a prompt you actually need - a real business, a real audience, a real call to action - and see how close the first draft lands. Check whether headings and structure make sense, whether the copy reads like your industry, and whether forms and navigation work. Then try a change and watch how faithfully the builder applies it. Quality of iteration matters more than the first render.
Watch for the exits before you invest time
Free is only fast if you can leave with your work. Some builders keep generated sites in a format you cannot move, or charge to export. It is worth confirming that you can take the code or repository with you and host it somewhere else. BYOB outputs standard that exports as a ZIP, which means the free experiment cannot become a hostage. That portability also lets a developer review the result before you commit budget to a plan.
When it is worth paying
Paying makes sense when a free constraint blocks something real: connecting the domain customers will type, handling more traffic, storing data, or adding accounts. Those are production needs, not vanity. A sensible path is to publish on a BYOB address for free, gather feedback, and upgrade only when a custom domain or an application feature is genuinely next. Paying earlier than that buys nothing you can measure.
Do not confuse free with finished
Even a good generated draft needs your judgement. Review the wording, replace placeholder images, check that contact details are correct and confirm the calls to action match how you actually work. A free tool removes the blank-page problem and much of the production cost, but it does not replace deciding what the business should say. Treat the output as a strong first version that you sign off, not an automatic finish line.
FAQ
Frequently Asked Questions
Is BYOB really free to try?
Yes. You can generate and preview a website without paying. Custom domains, higher usage and app features sit on paid plans.
Will a free builder put ads on my site?
BYOB does not place third-party advertising on generated sites. Publishing on a BYOB subdomain is available without a paid plan.
Can I export a site I built for free?
The project is standard and can be exported as a ZIP, so the code is yours to keep and host.
What is the catch with free AI website builders?
Usually limits: no custom domain, capped usage or restricted features. Check what each free tier excludes before you start.
At what point should I upgrade?
When you need a custom domain, more traffic capacity, data storage or user accounts - the point where the site becomes a real product.
