Business Website Builder
A business website is judged in a few seconds: can a visitor tell what you sell, whether you can be trusted, and how to get in touch? BYOB generates that structure from a short brief and keeps it editable as the business changes.

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

A business website builder should produce a site that wins work, not just a set of pages. BYOB generates the offer, services, proof, and contact flows a business needs from one brief, keeps them editable without code, and can grow into bookings, payments, or a customer portal later.
What a business site is actually for
Most business sites are asked to do three jobs: make clear what the business sells, convince a stranger it is credible, and give that stranger an obvious next step. Design matters, but so does structure, the order of the sections and the questions each one answers. BYOB generates a page hierarchy around those jobs, so the site opens with the offer rather than the company history, and the path to contacting you is never more than a click away.
Start from your offer, not a template
Templates start with someone else's business and ask you to swap in your own details. BYOB works the other way: you describe your customers, the services you sell, the areas you serve, and what a good enquiry looks like, and the generated pages mirror that. Service pages get names your customers would search for, and the homepage speaks to the problem you solve rather than a generic tagline. If the first draft misses, you refine it in chat instead of rebuilding from a blank canvas.
Services, pricing, and proof
Buyers want to know what something costs and whether others have trusted you. Generated pages can include a services or pricing section, testimonials, credentials, and a FAQ that answers the objections that stall a sale. You fill in real numbers and real quotes; the AI handles the layout, spacing, and responsive behaviour. Because every section is editable, you can change a price, add a case study, or remove a claim the moment it stops being true, which keeps the site honest.
Making it easy to get in touch
A contact form is often the highest-value component on the site. Forms generated by BYOB submit to your project inbox, so enquiries arrive somewhere you control instead of a third-party account you might forget. Ask for the details your follow-up needs, such as budget, timeline, or location, and trim fields that only add friction. Phone numbers, opening hours, an address, and a map can sit alongside the form for customers who prefer to call or visit in person.
Being found locally
Many businesses live or die on local searches, so the site should make your location and service area obvious in the headings and body copy. BYOB can generate pages that name the towns, regions, or neighbourhoods you cover, and structured contact details that search engines can read. Pair that with a verified Google Business Profile that points to the same site, and people searching nearby are far more likely to find a page that answers them.
Editing the site after launch
Websites go stale when every change requires a developer. In BYOB you click an element in the live preview and describe the change: a new service, changed opening hours, a seasonal banner, an updated team photo. Each edit lands as a normal change with version history, so a mistake can be rolled back. That means the person who knows the business best can keep the site current, and the site keeps earning after launch instead of quietly drifting out of date.
When pages are not enough
Some businesses eventually need more than pages: appointments, customer accounts, quotes, or a small internal tool. Rather than moving to another platform, the same BYOB project can gain login, data storage, and payment flows through built-in payments. The public site and the new functionality stay in one codebase, which is simpler to maintain and faster to run than stitching two systems together later.
FAQ
Frequently Asked Questions
Can I build a business website without coding?
Yes. Describe your business in chat, then refine the generated pages by clicking and typing. Code access is available if you want it, but it is not required.
How do I collect enquiries from the site?
Generated contact forms send submissions to your project inbox, so leads arrive in one place you control.
Can I update the site myself?
Yes. Service lists, prices, copy, and images are editable from the visual editor, and every change is versioned.
What if my business needs booking or payments?
The same project can add data-backed booking or payments through built-in payments as you grow.
Does a business site from BYOB rank in search?
It generates real pages with sensible headings and metadata, so the fundamentals are in place; rankings still depend on your content and competition.
