Custom Website Builder
A custom website should reflect a specific business, not a template everyone else is using. This page covers how to get a bespoke structure and design from a description, and how to keep customising it long after launch.

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
- Context tracking

A custom website builder lets you define the structure, look and functionality instead of choosing a fixed template. BYOB generates a bespoke site from your brief, keeps every element editable, and lets developers extend the same project with custom components, routes and data - so the site stays unique as it evolves.
Brief the site you actually need
Most builders ask you to pick a template first and adapt to it. BYOB flips the order: you describe the audience, the pages, the content hierarchy and the feel you want, and the generator proposes a structure built around that. Sections appear where your story needs them rather than where a template happened to place them. That starting point is specific to your business, which is the first requirement of a custom site.
Design direction without a blank canvas
A truly blank canvas is a hard place to begin. BYOB renders a complete draft with typography, spacing and a coherent visual system, so you react to something concrete instead of imagining from nothing. You can then push it in a personal direction: change the palette, adjust the type scale, tighten or soften the layout, and reorder sections. Because these are generated styles rather than locked theme presets, the design can be shaped rather than merely recoloured.
Custom needs real code
Anything genuinely custom eventually needs code. BYOB projects are standard, so adding an unusual component, a bespoke animation, a third-party embed or a custom connections route is a normal development task rather than an impossible one. There is no plugin marketplace standing between you and the feature, and no proprietary runtime to work around. Developers can open the project, read it, extend it and test it like any other repository.
Content that fits your structure
Custom sites often carry content that does not match standard blocks: a project timeline, a technical spec table, a portfolio with unusual aspect ratios. BYOB generates components you can reshape around that content rather than forcing it into a fixed form field. Add a section, drop a column list into a page, or build a repeated card from your own data. The markup stays readable and accessible, so the custom layout does not come at the cost of clean HTML.
One project from launch onward
The advantage of custom code is that it does not stop scaling. A site that starts as marketing pages can gain a booking form, a client login or a data-driven directory inside the same project. You avoid building the custom piece on a separate platform and trying to match it later. BYOB keeps the marketing site and the functionality in one editable codebase with a shared history, which makes long-term maintenance and handoff straightforward.
FAQ
Frequently Asked Questions
How is this different from a template builder?
Templates give you a fixed layout to fill in. BYOB generates a structure from your requirements, then lets you edit the layout, styles and code freely.
Can I fully customise the design?
Yes. Adjust colours, typography, spacing and section order, or edit the generated CSS and components directly for finer control.
What if I need custom functionality?
The project is ordinary, so developers can add custom components, routes and connections integrations without leaving the codebase.
Will I lose the custom work if I stop using BYOB?
No. Export the repository as a ZIP and host it yourself; the custom code travels with the project.
