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.

  1. 01 Describe the product Start with the outcome, audience, and any constraints. BYOB turns the idea into a practical build plan.
  2. 02 Shape the UX Review the proposed flows, screens, data needs, and visual direction before code starts moving.
  3. 03 Generate the app Tool Mode writes SvelteKit code, connects integrations, and keeps each change visible in preview.
  4. 04 Test and refine Ask for edits, roll back when needed, run checks, and keep the project editable instead of disposable.
  5. 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
npm
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.

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

A San Francisco construction website builder creates editable pages for project galleries, services, permit and licensing information and estimate request forms. BYOB generates the site from a prompt, stores leads in data storage, and keeps your CSLB licence number and service areas easy to update as your crew takes on new work.

Project galleries that prove the work

San Francisco homes are full of Victorian and Edwardian detail, narrow lots and awkward additions, and homeowners can tell immediately whether a contractor understands them. A gallery organised by project type - kitchen, bath, whole-home remodel, ADU, structural work - with before, during and after photos is the strongest evidence you can publish. Include the neighbourhood and the scope, not just a pretty final shot, because the messy middle is what proves competence. Update the gallery as each job completes so the site reflects your current work rather than years-old highlights.

Permits, seismic retrofits and ADUs

Almost every substantial San Francisco project touches the permit system. Soft-story retrofit requirements, accessory dwelling unit rules and historic-district reviews all affect scope and timeline, and homeowners are often anxious about them. A plain-language page explaining how permits work, what typically triggers a plan review and where to check status helps you look organised and honest. Link to the San Francisco Department of Building Inspection for the authoritative details, and always present this as general information rather than legal or engineering advice.

Licensing, insurance and homeowner trust

Before they invite anyone into their home or hand over a deposit, owners check credentials. Display your CSLB licence number, confirm you carry the insurance and bond required for the work, and explain what those protections mean in one or two sentences. Avoid vague claims about being the best or the fastest; specifics about crew, experience and process are more convincing. A short page on how you run a job - schedule, communication, change orders and cleanup - answers the questions that otherwise stall a promising enquiry.

Estimate requests and qualifying leads

A construction enquiry is worth more when it arrives with detail. A form that asks for project type, property neighbourhood, approximate budget range and ideal timeline lets you triage without a long phone call, and storing each submission in data storage keeps nothing buried in a personal inbox. Photos of the existing space can be uploaded and stored with the lead so you can assess feasibility before the first visit. A clear note on response time and what to expect next sets the relationship off on the right foot.

Service areas across the city and Bay Area

Whether you work only within San Francisco or across the wider Bay Area, being explicit helps people self-qualify. Short pages for the neighbourhoods and nearby cities you actually serve, from the Sunset and Richmond to the Marina, plus a clear list of services per area, improve local search and reduce out-of-area enquiries. Keep your Google Business Profile, business hours and service list aligned with the site. If you travel to the East Bay or Peninsula, say so and note any travel or minimum-project considerations up front.

Showing progress on long projects

Remodels run for months, and clients appreciate a window into progress rather than guessing. A project journal with dated photos and short updates can double as marketing and as a client communication tool, and finished projects become case studies with the homeowner's permission. Written testimonials collected at handover are far more persuasive than a star rating with no context. Over time this archive becomes the most credible part of the site, because it shows not just what you built but how you worked.

FAQ

Frequently Asked Questions

Can I show before-and-after photos?

Yes. Project galleries with before, during and after images are one of the strongest trust signals on a contractor site.

Can I collect estimate requests?

Yes. A form can capture project type, budget range and timeline, then store each lead in your data.

Does the site handle permits for me?

No. Permits are handled with the city; the site can explain the process and link to the San Francisco Department of Building Inspection.

Can clients upload photos of their space?

Yes. File uploads can be stored with the lead so you can assess a job before the first visit.

Do I need to display my licence?

California contractors should display their CSLB licence number in advertising; check current requirements.
