Fast Web Sites Without the Hidden Costs
A real site should go live in about 30 seconds, not after weeks of setup and a stack of hidden fees. BYOB OnePage turns one prompt into a complete, editable site — the same product as the full app — and extends into data, accounts and more pages whenever you need them.

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.

- Voice coding
- Project templates
- SEO-ready output

What a fast web site really costs
A headline monthly price hides the parts that decide the real bill: how many pages you can publish, how much traffic you get before overage, and what happens at renewal. A plan advertised as inexpensive can double when a promotional year ends. Reading the renewal price and the usage limits tells you far more than the first invoice, and it is the honest basis for comparing two options.
The line items that quietly raise a bill
Watch for per-page charges on multi-page builders, visitor caps on landing-page tools, paid SSL or analytics add-ons, and premium templates sold separately. Some platforms also take a cut of sales or lock a domain to their publishing. None of these are scams, but together they turn a fast tool into a recurring cost. A site sidesteps most of them because there is only site and no store to commission.
Why site costs less to run
A single lightweight page needs fewer resources than a multi-page site with data storage and admin panel. It loads faster, hosts for less and does not require a CMS to update. That matters when you are paying by usage: fewer moving parts mean the page stays within a free or low tier for longer. The savings are not just the plan fee but the maintenance you never have to do.
Free to generate, paid to grow
BYOB OnePage lets you generate and publish a site without paying to start, so you can validate an idea before committing. Paid plans exist for custom domains, higher usage and the full app builder, which means cost tracks value rather than arriving before you have a visitor. That order, prove it first and pay later, is the opposite of how most typical subscription website builders work.
Looking sharp without the agency bill
Low cost should not show in the design. A generated page follows the same structure as an expensive landing page: clear headline, real benefits, proof and one call to action. Keeping it fast and uncluttered usually reads as more professional than a heavily templated site overloaded with widgets. Visitors judge credibility in seconds, and speed and clarity are free to get right.
FAQ
Frequently Asked Questions
Can I build a website for free?
You can generate and publish a OnePage site free to start. A custom domain and heavier usage are the point where paid plans make sense.
What is usually the biggest hidden cost?
Renewal pricing and usage limits. A promotional first-year rate often rises sharply, and traffic caps can force an upgrade.
Do I need to pay for publishing separately?
No. The generated site is hosted as part of BYOB, so there is no separate publishing bill to manage for a siter.
Is a fast-generated site bad for SEO?
No. Sites can rank well for focused terms, and a fast, lightweight page is an advantage rather than a drawback.
Can I move to a paid plan later?
Yes. Start free, then upgrade when you want a custom domain, more usage or a full data-backed application.
