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.

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's Supabase integration inspects an existing Supabase project, then generates SvelteKit screens with matching TypeScript types, queries and login flows. You keep your own data source, row-level security and migrations under your own control, while the AI writes the frontend code that connects users to that data.
Keep the backend you already trust
If your data lives in Supabase, moving it to a new service is rarely worth the risk. This integration treats Supabase as the source of truth and only generates the layer above it. Your tables, foreign keys, policies and backups stay exactly where they are, managed through the Supabase dashboard and CLI you already use. BYOB acts as the frontend engine, producing the SvelteKit routes and components that read from and write to your schema.
Schema inspection and type generation
The first step is understanding what you have. BYOB reads your Supabase schema and derives TypeScript types for tables, columns and relationships. Generated queries and form handlers then use those types, so a misspelled column or a nullable field is caught at build time rather than in production. The result is frontend code that behaves like it was written by someone who knew your database from the start, because it effectively was.
Authentication that respects your setup
Supabase Auth handles sessions, providers and user records. BYOB does not replace it with a competing scheme; it generates login, signup, password reset and protected route guards that talk to your Supabase configuration. Because requests carry the user's session, your row-level security policies continue to apply exactly as intended. Pages that should be private stay private, and each user sees only the rows your policies permit.
Migrations and version control
Schema changes deserve the same care as application code. When a feature needs a new table or column, BYOB can draft the SQL migration for review instead of altering your database silently. You apply it through Supabase's migration tooling, keeping a reviewable history that matches your repository. The frontend is regenerated against the updated schema, so database and interface evolve together with a clear, auditable trail rather than undocumented manual edits.
Supabase or the built-in database?
Not every project needs your own data source. BYOB also offers a managed Cloudflare D1 database, which is simpler when you are starting fresh and your data model is modest. Choose Supabase when you depend on your own data source, extensions, nuanced RLS or an existing team workflow. Either way, the generation experience is the same: describe the screens you need and BYOB writes the code that connects them to durable data.
FAQ
Frequently Asked Questions
Does BYOB replace my Supabase project?
No. Supabase remains your backend. BYOB reads its schema and generates the SvelteKit frontend, leaving your database and policies intact.
Will the generated code be type-safe?
Yes. Types are derived from your Supabase schema, so queries and forms use columns and relationships that genuinely exist.
Can it handle Supabase row-level security?
Yes. Generated requests carry the user's session, so your existing RLS policies continue to govern access.
Does it create migrations automatically?
It can draft SQL migrations for review; you apply them through Supabase so the schema history stays under your control.
