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.

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 Mumbai creates editable pages for class timetables, trainer profiles, membership plans and trial signups, with payments through UPI or built-in payments. BYOB generates the site from a prompt, stores enquiries and health forms in data storage, and lets your team update schedules without a developer.

Timetables that update in seconds

A schedule is the most-visited page on most gym and studio sites, and the one most likely to go stale. Build a weekly timetable grouped by class type, level and trainer, and make each entry editable so a cancelled session or a new batch is fixed the same day. Show studio location and first-timer instructions alongside the schedule. A timetable people trust reduces the 'is the 7am class running?' messages that eat into a front-desk team's morning.

Trainers and the classes they teach

Members join people as much as programmes. Give each trainer a profile with certifications, specialities, and the classes or personal-training slots they run, and link those profiles from the timetable. Authentic credentials matter in a market with plenty of unverified 'expert' claims, so state qualifications accurately. These pages also capture searches for a specific discipline, whether that is strength training, yoga or rehabilitation, and give your team something worth sharing.

Trial passes and membership sales

The trial is your best sales tool, so make claiming one effortless. Add a trial-pass form that captures details into data storage, and present membership tiers clearly with what each includes and any joining fee. Take payment for memberships or class packs through built-in payments or an UPI link; BYOB does not run a native card checkout, so keep the actual transaction with your payment provider. A clear path from curious to booked trial is what fills a studio.

Local discovery for gyms and studios

Fitness searches are intensely local: 'gym near Powai', 'yoga classes in Bandra', 'personal trainer in Thane'. Publish a page for each area you serve, keep your Google Business Profile accurate with photos and timings, and gather reviews from members. A.in or.com domain that matches your brand reinforces locality. These simple steps bring the person who is comparing two studios within walking or a short commute of home or work.

Beyond the site: a member area

When the community grows, the same BYOB project can hold a login-protected member area with class credits, attendance history and progress notes. Authentication keeps each member's data private, and data storage stores bookings or check-ins. You can also let trainers update programmes or share resources. Because it is one codebase, the public site and the member tool share a design and never drift apart, so you are not buying yet another subscription for a small feature.

FAQ

Frequently Asked Questions

Can I sell memberships online?

You can take payment through built-in payments or an UPI link and record the membership. BYOB does not run a native card checkout itself.

Can members book classes?

Yes, a simple booking form can store requests or check-ins in data storage. It is not a full gym management system.

Can I show a weekly schedule?

Yes. The timetable is an editable page, so cancellations, new batches and holiday changes can be published quickly.

Can I collect health forms digitally?

Yes. A pre-participation form can record health details and consent into your data, which is more consistent than paper.

Is it suitable for a single personal trainer?

Yes. One trainer can start with a profile, packages and a trial form, then add a member area later.
