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

BYOB builds a Kolkata construction company website from a prompt: project galleries, service pages for civil, turnkey and interior work, quotation forms and a credentials section. You update projects and photos yourself and publish on your own domain, giving clients proof of work before they call.
Project galleries that win work
Construction clients judge you by what you have already built. Publish finished projects with photos, location, scope and duration, grouped by category such as residential, commercial, interior or civil. A dated before-and-after set for a Salt Lake office fit-out or a Rajarhat home says more than any brochure, and BYOB lets you add each new project as a simple entry.
Service pages for civil, turnkey and interior work
Buyers search for a specific service, not the word 'construction'. Create a page each for turnkey home construction, civil contracting, interior fit-outs and renovation, describing scope, typical timelines and what is included. Clear service pages help a homeowner in Behala and a facility manager in Sector V both find the page that matches their project, and they give search engines a specific topic to rank for.
Quotation and site-inspection forms
Most enquiries start with a rough budget and a request for a site visit. Generate a form that captures project type, plot or site location, area and timeline, and route it into data storage dashboard. Your team can then prioritise genuine leads, schedule inspections and keep a record of who quoted what, instead of juggling details across phone calls and forwarded messages.
Approvals, safety and credibility
Building in Kolkata involves municipal permissions, and clients worry about compliance. Present your registration details, safety practices and any relevant certifications plainly, and explain how you handle plan sanctions and approvals. Showing that you understand the paperwork reassures both individual owners and commercial clients, and it distinguishes a serious, accountable contractor from an informal team of masons with no traceable record.
Local search for ward-level projects
Construction enquiries come from a radius around your last job site. Name the areas you serve, such as Ballygunge, Jadavpur, Howrah or New Town, in your page titles and content, and keep a Google Business Profile map on the contact page. A fast, honest site that loads on a phone at a site visit is what actually converts a search into a callback.
FAQ
Frequently Asked Questions
Can I add new project photos myself?
Yes. Add projects and photos through a simple form or the visual editor, and they appear on the live site immediately.
Can the site collect quotation requests?
Yes. Generate an enquiry form that captures project type, location, area and timeline, then manage leads in a dashboard.
Can I build separate pages per service?
Yes. BYOB can generate individual pages for turnkey, civil, interior and renovation work so each service ranks on its own.
Do I need a developer to maintain the site?
No. You edit content visually or by chatting with the AI, and the underlying code stays yours to export.
