BYOB New inbox in every project
AI SaaS Website Builder
A SaaS product has to solve the boring problems before it can solve an interesting one. BYOB generates the account, session, settings and payment scaffolding from a short description of your product, so your first sprint goes into the feature customers actually pay for.

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

BYOB is an AI SaaS website builder that generates the common SaaS foundation - login, protected routes, a settings area, billing screens and persistent data - from a prompt, then publishes the app to a public URL where you can connect your own domain.
The unglamorous parts, generated first
Every SaaS begins with the same four screens: sign up, sign in, account settings and somewhere to manage a plan. Describing that base to BYOB produces working routes and forms for each, wired together with sessions so a signed-in user is recognised across the app. Instead of staring at an empty repository, you start from a product with a front door, a place to change an email address, and a settings page that already saves. From there every later feature is an addition rather than groundwork, which keeps early momentum and lets you demo something real to testers and investors far sooner.
Authentication without the boilerplate
BYOB projects use Better Auth for sessions. You can offer email magic links, Google sign-in, or both, and generate protected routes that redirect anonymous visitors to a login page. Because the login layer lands as ordinary code in your project, you can adjust redirect logic, add a provider, or move to a different strategy later without rebuilding the app. Password resets, session expiry and the difference between public and private pages are handled as part of the same generated structure, so security basics are not an afterthought you bolt on once customers start signing up.
Billing screens you can connect
BYOB scaffolds the pricing page, the plan-selection flow and an account billing view. Payment processing itself is handled by providers such as built-in payments, which you configure with your own account keys, so money and tax obligations sit with the provider while the interface stays inside your app. This keeps you in control of checkout copy, trial messaging and upgrade prompts. You can launch with a free tier, add paid plans when demand appears, and change how plans are presented without touching the provider that actually moves the money.
Where the data lives
Accounts, preferences and app records need durable storage that survives a restart. built-in data storage covers most SaaS projects without extra setup, and teams that already run your own data source can connect a data source instead. The generated frontend matches whichever schema you choose, so tables, forms and queries stay consistent as the product grows. When you add a new field or relationship later, the same generation workflow updates the interface to match, which means the data model and the screens users see do not drift apart over months of changes.
From shell to shipping
Once the foundation is live you can keep building features through prompts or by editing the code directly. Deploy to a BYOB URL, attach a custom domain, and iterate in public with real users rather than a demo. Because the output is a standard project with version history, nothing about the scaffold traps you on the platform: you can export it, hand it to a developer, or move publishing whenever your needs change. That combination of a fast start and an open exit is what makes the generated foundation safe to build a business on.

FAQ
Frequently Asked Questions
No. BYOB generates the billing interface; you connect built-in payments with your own keys, or leave payments out until you are ready.
Yes. Connect a data source and BYOB reads your schema so generated screens match your existing tables and login setup.
It is closer to a generated foundation: you get real code for login, settings and billing screens rather than a licensed template you keep paying for.
Yes. Continue prompting for changes or open the code editor; every edit stays in version history.
