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.

A fitness website builder for Seattle creates class schedules, trial sign-up and membership pages, online waivers and trainer profiles for gyms and studios. BYOB generates them as pages from a prompt, stores bookings and waivers in your own data, and supports built-in payments for membership billing.
Schedules and trial sign-ups that fill classes
Seattle's fitness market is built on small studios with loyal members, and the first step is usually a free or fast trial class. Publish a clear weekly schedule, let people reserve a spot through a form stored in your data, and send a simple confirmation. If you run on Mindbody, ClassPass or a similar platform, link to it instead of duplicating it. Show the class type, level and duration so the right people book, and make the trial button visible on every page rather than buried in the footer.
Memberships, class packs and recurring billing
Studios here sell a mix of monthly memberships, class packs and drop-ins. Describe each tier with what it includes and how to cancel, because unclear contracts are the fastest way to lose goodwill. Recurring membership billing can run through a supported payment provider; BYOB uses built-in payments rather than a native checkout, so you connect the plan that fits your business. Keep prices and inclusions on the site in sync with whatever you charge at the desk, and show an intro offer that gives newcomers a low-risk way in.
Online waivers and health forms
Every gym and studio needs a liability waiver, and collecting it before the first class saves time at the door. A waiver form can be filled in and stored in your data, alongside a basic health questionnaire for new members. Keep the wording honest and have it reviewed by a professional; the site simply gives people a clean way to complete it. Storing signed forms digitally means a coach can confirm a participant is cleared without hunting through paperwork, which matters on a busy weekday evening.
Coaching for a rainy, active city
When the trails are wet and the days are short, Seattle trains inside. That plays to the strength of climbing gyms, rowing clubs, strength studios and small-group training, and the site should say so plainly. Describe the atmosphere and the format rather than leaning on stock fitness photos. Neighbourhood matters too: people in Ballard, Capitol Hill or South Lake Union choose studios they can reach after work, so name your area and mention transit or parking alongside your class times.
Trainer profiles and honest credentials
Members follow coaches. Short profiles that list a trainer's specialty, certification and the kind of client they work best with help people choose a class or a one-to-one block. Only claim qualifications the person actually holds. Specialties like pre and postnatal training, strength work, climbing technique or endurance coaching each appeal to a different member. Pairing profiles with the schedule makes it easy to book with a specific coach, which is often what turns a drop-in into a membership.
Local search and community events
Fitness searches are local: a climbing gym in Ballard, pilates nearby, a personal trainer in Capitol Hill. Keep your Google Business Profile current with hours, photos and a class link, and create short pages for the areas you serve. Community events, challenges and beginner courses give the site fresh reasons to be visited and give members something to share. A newsletter keeps your list warm between sessions, so a new timetable reaches the people most likely to sign up.
FAQ
Frequently Asked Questions

Can I bill monthly memberships?
Recurring billing runs through a supported provider such as built-in payments; BYOB does not have a native checkout.
