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.

BYOB helps a Liverpool gym or trainer generate an editable site with class timetables, online booking, membership plans, recurring payments and free-trial forms, ready to launch in a day. Your team updates schedules, prices and offers without waiting on a web developer.
Timetables and class booking
A club timetable that lives only on a noticeboard loses bookings. Publish your class schedule, let members reserve a spot, and run a waitlist so popular sessions do not show up half empty. Personal trainers can offer bookable one-to-one slots with their own availability. Liverpool has a strong fitness culture that runs from waterfront parkruns and Sefton Park loops to lunchtime sessions near the commercial district, and clients expect to book from a phone between meetings. BYOB generates the schedule and booking logic as editable pages you can update when the timetable changes each term.
Memberships and recurring payments
Recurring revenue keeps a gym alive. Sell monthly memberships, class packs and pay-as-you-go drop-ins, and choose a payment method that suits your members: recurring card payments for boutique studios, or a direct-debit provider for larger clubs. Offer a discounted first month or a free trial class to turn a curious visitor into a member. BYOB can generate the plan pages, sign-up flow and a member area backed by a real data, so you can see who is active and pause or renew plans without maintaining a spreadsheet by hand.
Show the space and the coaches
People join gyms they can picture themselves in. Use real photos of your floor, studio and changing rooms, and feature the trainers who make the place feel welcoming. A short walkthrough video helps a member decide before they travel across the city to a site near the docks or in the Knowledge Quarter. Highlight the community side too, such as beginner-friendly classes and small-group sessions, because first-timers worry about feeling out of place. BYOB makes these a couple of editable sections rather than a custom build, so updating coach profiles takes minutes.
Leads, trials and local search
Most new members start with a search like gyms near me or personal trainer Liverpool. Build a page per location or service, keep your Google Business Profile accurate, and put a free-trial or tour-request form on every page so interest converts immediately. Add class-specific pages for things people search for, such as reformer pilates, spin or strength coaching, and link them to your timetable. BYOB pages ship with editable metadata, so your local search presence improves as you publish new programmes and offers across Merseyside.
Online coaching and challenges
Coaching does not have to stop at the gym door. Sell online programmes, six-week challenges or remote PT check-ins, and deliver plans and progress tracking through a member portal. Liverpool clients who travel for work or study value that flexibility, and it gives you revenue that is not tied to floor space. BYOB can generate the programme pages, a secure login area and a place to store client progress in the data, all in the same project as your timetable and memberships.
FAQ
Frequently Asked Questions
Can members book classes online?
Yes. You can publish a timetable with reservations and a waitlist, and store bookings so your team sees class numbers in real time.
How should I take membership payments?
Recurring card payments suit small studios, while larger clubs often use a direct-debit provider. BYOB connects to supported providers for plans and one-off passes.
Can I offer a free trial?
Yes. Add a trial-request form to every page, capture the lead in your data, and follow up automatically.
Do I need separate pages for each class?
It helps with search. Pages for popular classes like pilates, spin or HIIT match how people search and can link straight to the timetable.
