BYOB New inbox in every project

Membership Website Builder

A membership business has two audiences in one project: people deciding whether to join, and members who already have. The public side sells the value; the private side has to deliver it behind a login.

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

BYOB is a membership website builder that generates the public sales pages first, then extends the same project with login, protected member pages and data-backed records. You keep one editable codebase, so marketing copy and member experience do not drift across two separate tools.

Sell the membership on the public pages

Before anyone logs in, they need to understand what membership gives them and what it costs. BYOB generates a benefits section, a comparison of free and paid access, pricing tiers and a FAQ that answers cancellation and billing questions up front. Deciding what to keep private is a positioning choice, and the public pages should be persuasive enough that the sign-up feels like the obvious next step.

Design the member experience

A member area is a small product in its own right. BYOB can scaffold a welcome dashboard, a library of gated resources, a profile page and an updates feed, all matching the visual style of the public site. You describe the resources members should reach, and the AI generates the routes and layouts. Keeping both halves in one codebase means a change to your brand colours applies everywhere at once.

Accounts and protected content

Membership requires identity, so the project needs login. BYOB can generate sign-up, sign-in and password-reset screens and protect routes so only signed-in members see gated pages. The login layer sits alongside the pages rather than being bolted on, which keeps the user experience consistent. This is the step where a membership site stops being a website and becomes an application.

Storing member records

Once people join, you accumulate data: profiles, join dates, plan tiers and activity. built-in data storage gives you persistent storage without provisioning a server. The AI reads your schema and can generate components that display or edit member records. If your organisation already uses your own data source, the data source integration lets you point at an existing project and stays type-safe.

Pricing pages that match your model

Membership pricing is rarely a single number. You might offer monthly and annual plans, a founding-member tier, or a free level that upsells later. Generated pricing sections are easy to restructure in chat, so you can add a tier or change the emphasis without a redesign. Billing itself is handled by a provider such as built-in payments; BYOB builds the page and the account flow around it.

FAQ

Frequently Asked Questions

Can members log in and see private content?

Yes. Extend the project with login and protect routes so only signed-in members reach gated pages.

Does BYOB handle subscription billing?

No. BYOB generates the pricing and account screens, while recurring payments run through a provider such as built-in payments.

Where is member data stored?

In built-in data storage on, or in your own an existing your own data source project if you connect one.

Can I start with just the marketing site?

Yes. Begin with the public pages and add the member area later without migrating to a new platform.
