BYOB New inbox in every project
Site Builder
A site asks a visitor to do exactly one thing, and every section should support that goal. BYOB generates the page as a real project, so you refine the structure instead of fighting a locked template.

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.
- Added lines highlighted the moment they land
<script lang='ts'>type Task = { id: string; title: string; done: boolean
}let tasks = $state<Task[]>([])function toggleTask(id: string) {task.done = !task.done // just added by BYOB}</script>02 · AI COMMAND
Plan, build, and refine in one chat.
Describe the outcome once. BYOB turns it into a build plan, implements it step by step, and keeps every change visible while you iterate.
- Build plan with live progress you can inspect
Your prompt
“Build a todo app for beginners”
Build plan
80%- Task list UI + empty state
- Add + toggle actions
- Progress summary…
03 · LIVE PREVIEW
See every change the second it lands.
The preview updates as BYOB works, with deploy status attached, so the path from edit to production stays inspectable.
- Real app state, not a static mockup
Team Tasks
Shared task tracking
- Wireframe landing page
- Task list component
- Responsive polish + QA
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.
- Approve project access from BYOB
- Installs the byob command
- Preview, deploy, git diff, DNS, credits, and code tools
npx -y byob-cli codex install Approve only the projects your agent can touch, then read context, edit files, inspect diffs, test previews, and roll back from your terminal.

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
- Model lock

A website builder generates a complete site from a description: hero, value sections, proof, FAQ and one primary call to action. BYOB builds these as editable pages you can refine by chatting or clicking any element, then publish free.
When a site beats a full site
One long page suits offers with a single decision: a product launch, a waitlist, an event, a freelancer's services, or a campaign that runs for a few weeks. Visitors scroll instead of navigating, which keeps attention on the offer and removes the dead ends that multi-page sites often create. It also means one link to share everywhere, whether that is a QR code on a flyer, a bio link, or a paid ad. If the project later needs separate pages, you can add routes without rebuilding what already works.
How BYOB generates the page
You describe the offer, the audience and the action you want, and BYOB drafts the whole page: a headline, supporting sections, a FAQ and a call to action. It writes this as a route rather than filling a locked template, so the result is a normal web project with real components, styles and content. The first draft is a starting point. Ask for a different tone, swap the section order, or add a testimonial block, and the preview updates as you go.
The blocks a focused page needs
Most effective sites repeat the same handful of blocks in different orders: a clear hero, a short explanation of the problem, two or three benefit sections, social proof, a pricing or plan area, objections answered in a FAQ, and one repeated call to action. BYOB generates a sensible arrangement from your description, then lets you delete what does not apply. Because each block is editable, you can turn a generic features grid into a specific proof section without touching a layout tool.
Edit by chatting or clicking
The visual editor lets you change text, images, spacing and colours directly on the page. For larger changes, describe what you want in chat - move the pricing table above the FAQ, make the hero headline shorter - and BYOB edits the underlying project. Every change is versioned, so you can compare drafts and roll back if a rewrite makes things worse. You are never stuck with a decision made in the first generation, which is the main difference between generating a page and buying a fixed template.
Publish and point a domain at it
When the page is ready, publish it with one click and share the live URL. You can attach a custom domain, and BYOB handles the connection so the page answers on your own address rather than a long temporary link. If you would rather host it yourself, export the project as a ZIP and run it wherever you like. There is no separate page builder to maintain and no platform holding your content hostage; the page is part of a project you control.
Leave room to grow
A site is a starting point, not a ceiling. If demand grows, add a second route for a case study, a blog, or a checkout flow using the same project, login and design system. Because the first page was generated as code, extending it does not mean starting again. You keep one codebase, one publishing and one place to make changes.
FAQ
Frequently Asked Questions
It can rank well for a focused topic because all the content sits on one address, but it competes poorly for many different searches. If you need to target lots of keywords, add separate pages later; the project supports it.
Yes. The site is generated as a route, so you can add more routes in the same project and link them into the navigation.
Generating and publishing a site is free to start. Custom domains and higher usage sit on paid plans, which are listed on the pricing page.
Yes. After publishing you can connect a domain you own, and BYOB configures it for the published site.
Yes. Contact and signup forms can post to your project, and you can store submissions in data storage or forward them to email.
