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

A fitness website builder for Bristol creates pages for timetables, memberships, class and trial bookings and trainer profiles. BYOB generates them as editable pages from a prompt, takes membership or drop-in payments through built-in payments, and lets staff update the schedule without a developer.
Timetables and memberships in one place
The two questions a new member asks are what is on and what it costs. Publish a weekly timetable grouped by class type and a membership page that explains tiers in plain words, including what is unlimited, what is capped and how to pause. If you offer pay-as-you-go alongside monthly plans, show both so nobody feels trapped. Because the timetable is editable, a coach or front-desk staff member can move a class, cover a holiday period or swap an instructor without waiting on a web developer, which keeps the site as reliable as the noticeboard by the door.
Trials, drop-ins and a booking path that converts
Most Bristol studios live on the conversion from a first visit, so make the free trial or intro offer prominent rather than buried in a menu. Link to your class booking system, and where you take payment directly, a card checkout through built-in payments handles drop-in classes and memberships. For personal training or coaching blocks, a short enquiry form collecting goals, preferred times and experience level filters the serious enquiries from the curious. Store those leads in data storage so nobody falls through the cracks during a busy January sign-up rush.
Coaches and community
People join a gym for the room as much as the equipment. Give each coach or trainer a profile with their specialisms, whether that is strength, rehab, endurance, yoga or climbing, plus qualifications and a photo. A short page about the community, the atmosphere and the kind of member you suit helps the right people self-select. Running clubs, social rides and beginner courses are worth their own pages because they attract newcomers who might never have entered a gym before. Real photos and honest descriptions outperform generic fitness stock every time.
Getting found by people nearby
Fitness searches are intensely local: a gym near Clifton, a pilates class in Bedminster, a climbing session near the harbourside. Name the neighbourhoods and postcodes you serve on relevant pages so you can appear for those searches, and keep your Google Business Profile hours, photos and booking link current. A domain that matches your studio name is easier to share by word of mouth. Since many enquiries come from people who have just moved to Bristol, a short page on parking, bike storage and public transport removes a real barrier before the first visit.
When members need more than a schedule
As the community grows, the website can become a lightweight member tool. Add login so people can see their bookings, store waivers and health questionnaires in data storage, or publish a members-only page for challenges and event sign-ups. built-in data storage or a data source handles the data, and the email broker can send schedule changes or a monthly newsletter. Because it is one project, the booking page, the shop for merchandise and the member area stay consistent instead of becoming disconnected tools that each need separate upkeep.
FAQ
Frequently Asked Questions
Can I update the class timetable myself?
Yes. Timetables and class copy are editable visually or in chat, so staff can move, add or cancel a session without a developer.
Can members pay online?
Yes. Drop-in sessions and membership payments can be taken by card through built-in payments, while class booking can link to your existing system.
Can I capture trial sign-ups?
A free-trial or intro-offer form can collect goals and preferred times, store them in data storage and route them to your inbox or dashboard.
Is it suitable for personal trainers?
Yes. A solo PT can present packages, testimonials and a consultation form, while studios can add timetables and coach profiles.
Can I add a members-only area later?
Yes. The site can grow into a member area with login using built-in data storage or a data source, without rebuilding the marketing pages.
