No-Code Website Builder
BYOB lets you describe a website and get a working draft without touching code. The difference is what happens underneath: the result is a real project rather than a locked canvas, so you are never stuck if your needs change.

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.

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

A no-code website builder lets you create a site through prompts, clicks, and visual editing instead of programming. BYOB generates a real project from your description, so you can launch without writing code yet still access the source if you later want deeper control.
What you can build without coding
Small-business sites, landing pages, portfolios, event pages, and simple product sites are all reasonable no-code projects. You can generate navigation, hero sections, feature grids, pricing tables, testimonials, and contact forms, then rearrange or rewrite them by describing the change. Because the AI handles layout and styling, you focus on content and structure. There is no need to learn a grid system or a CSS framework to get a page that looks finished.
Forms and data without SQL
Static pages are only part of the story. When a no-code site needs to store something, BYOB can connect data storage so form submissions, signups, or listings persist. You describe the data you need, and the builder scaffolds the storage and the screens that read it. You are not writing SQL or wiring a connections by hand unless you choose to.
Know the trade-offs
No-code is fastest when the design follows common patterns. If your site needs a highly unusual interaction or a bespoke integration, generation still gives you a head start, but a developer may need to finish the last mile. The advantage of BYOB is that this handoff is simple, because the code is already real and readable rather than a proprietary export.
A path beyond no-code
Many people start no-code and stay there. Others grow into editing the generated project as their needs expand. Because BYOB keeps a full codebase and version history, moving from prompts to code is a gradual step rather than a migration. You can open one file, change one value, and keep everything else exactly as the AI built it. Over time, that gradual exposure can turn a no-code user into someone who comfortably reads and edits a project.
FAQ
Frequently Asked Questions
Is no-code really possible for a real website?
Yes. For most small business, portfolio, and landing-page sites, prompts and visual editing are enough. Complex custom logic is where coding help may eventually be useful.
Will I be locked into BYOB?
No. You can export the full project as a ZIP and host it anywhere.
Can a no-code site have data storage?
Yes. BYOB can add managed storage so forms and user data persist, without you writing schema migrations by hand.
Do I need to understand?
Not to build or edit a site. It is there if you want to learn or hand the project to a developer.
