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.

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.

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.

- Installs the byob command

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

BYOB is free to start: you can generate a website, edit it, and preview it without paying. Costs appear when you outgrow free usage or want a custom domain, and paid plans add those. You can export the project at any time.
What free actually gets you
The free tier is meant for real evaluation, not a limited demo. You can describe a website, generate a full project, edit it in chat or visually, and view it in a live preview. That is enough to judge whether the output is the quality you want and whether the workflow suits you. You do not need a credit card to find out.
Where paid plans begin
Paying starts making sense when a project moves from experiment to production. Custom domains, higher generation limits, and team-oriented features sit on paid plans. If you are only testing an idea or drafting a page, the free workflow is usually sufficient. Check the pricing page for current limits rather than relying on second-hand comparisons, because plans change. The goal is to pay for production needs, not for the ability to try.
Free subdomain versus custom domain
Free projects publish to a BYOB URL, which is fine for sharing a draft or previewing on a phone. A custom domain, such as yourbusiness.com, needs a paid plan. If your main goal is a recognizable address for customers, budget for that rather than hunting for a free domain promotion that often bundles renewal costs later. If you plan to grow, treat the domain as part of the budget from the start.
Avoiding lock-in on a free tier
Some free builders make leaving painful: your site only exists inside their editor and nothing useful comes out. BYOB's free tier still produces a standard project you can export as a ZIP. That matters because the fastest plan is not really fast if abandoning it means rebuilding from scratch. Owning the output is part of what you get regardless of tier.
The fastest way to evaluate a builder
Start with the site you would actually build, not a throwaway toy. Generate it, refine it, and try the edits you expect to need in production, such as changing a layout or adding a form. If the free workflow handles those, you have a realistic signal about fit. If it does not, you have learned that before spending any money.
FAQ
Frequently Asked Questions
Is BYOB completely free?
No. It is free to start and evaluate. Custom domains and higher usage are paid features.
Do I need a credit card to try it?
You can generate and preview a project without one. A card is only relevant when you choose a paid plan.
Will a free site carry BYOB branding?
Sites are ordinary projects. Check the current plan details on the pricing page for any tier-specific branding.
Can I keep my site if I stop paying?
Export the project as a ZIP. It is standard code you can host elsewhere.
