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

For a Paris retailer, BYOB builds an elegant storefront with French-first content, EUR pricing and VAT at 20% handled at checkout. It supports Apple Pay and major cards and a.fr domain, so customers in Paris and across France can browse and buy with confidence.

The arrondissement advantage for independent shops

Paris retail is intensely local. A boutique in Le Marais, Montmartre or the Batignolles draws a loyal nearby following, and that neighbourhood identity can shape the whole website. Use local references, opening hours that reflect the area's rhythm, and clear metro directions so people actually visit. For stores with more than one address, give each its own page. Letting the online store echo the personality of the physical shop, rather than looking like a generic template, is how small Parisian retailers compete with larger chains.

Fashion weeks, tourism and the international shopper

Paris receives a steady flow of visitors, and demand spikes around fashion weeks, trade fairs and the summer holidays. A store that welcomes international customers should state sizes, shipping destinations and return rules in plain French with an English toggle. Offer guidance on delivery to hotels and gift packaging, which tourist buyers value. Residents, meanwhile, care about repairs, exchanges and loyalty. Serving both audiences in one coherent storefront avoids the trap of a site that only makes sense to locals.

French copywriting that never reads translated

French shoppers notice clumsy language immediately, so product descriptions, size guides and policies should be written naturally rather than translated word for word. Use correct accents and typographic conventions, and keep a warm but precise tone. Category names and filters should match the words customers actually use. Good French copy also helps visibility in local search, where phrasing and spelling carry weight. Where you sell internationally, add English beside French rather than replacing it, so neither audience feels like an afterthought.

Click-and-collect and the Paris delivery map

Paris is dense, and many customers prefer to reserve online and pick up at the shop. Click-and-collect shortens delivery expectations and lets people see goods before committing. For the rest of France, state realistic courier times and fees, and note that fragile items ship better in protective packaging. Because the city's streets, parking and building access vary enormously, make pickup instructions specific. A clear, honest logistics section does more for repeat business than a vague promise of fast delivery.

Between the soldes: keeping the store alive

French retail is built around two regulated sale periods, in winter and summer, along with Christmas and the September rentree. Outside those windows, year-round discounting can erode a premium position. Instead, use editorial content, styling guides and seasonal emails to keep the store useful and visible between campaigns. Plan stock and campaign pages well before each peak so the site stays fast under extra traffic. A steady content rhythm, rather than constant promotions, is what sustains an independent Paris label.

FAQ

Frequently Asked Questions

Must my Paris shop's site be in French?

French customers strongly prefer French content, and national commerce rules encourage it. Lead with French and offer English as a secondary option for international visitors.

How is VAT shown on French retail prices?

French consumers expect VAT-inclusive prices, with VAT at 20% built into the displayed amount. Keep this consistent across products and at checkout.

Do Paris customers use Apple Pay?

Yes. Apple Pay and major cards are widely used, so supporting them removes friction for both local and visiting shoppers.

Is click-and-collect worth offering?

In a dense city like Paris, reserve-and-collect is popular and shortens delivery expectations. It also gives customers a reason to visit the shop in person.
