AI Chat App Builder
Chat is a deceptively fiddly interface: empty states, message grouping, scroll behaviour and error handling all have to work together. BYOB generates that interface and the storage behind it, so the conversation is real rather than a static mock-up.

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.

Plan, build, and refine in one chat.
Describe the outcome once. BYOB turns it into a build plan, implements it step by step, and keeps every change visible while you iterate.

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.

- Voice coding
- Project templates
- SEO-ready output

BYOB is an AI chat app builder that generates a working chat interface - message list, composer, typing and empty states - plus the routes to store conversations. You connect whichever AI model you prefer, or run the app as a messaging layer over your own data.
The interface details that take time
A chat screen looks simple and hides a lot of work. BYOB generates the scrollable message list, the input composer, a send button with pending state, typing indicators and sensible empty and error states. Buttons disable while a request is in flight, so the UI does not accept a double send. These details are usually the difference between a demo and something people will actually use.
Storing conversations
Messages need somewhere to live if users are to come back to them. The generated app can write each turn to built-in data storage giving you conversation history, per-user threads and a schema you can query. If you already run your own data source, connect a data source and the generated screens will match your existing tables. Storing messages yourself also unlocks features that are hard to add later, such as searching past conversations, exporting a transcript, resuming a thread on another device, or showing a summary on a dashboard.
Choosing the intelligence behind it
BYOB builds the application around an AI provider rather than forcing one. You can point the chat at a hosted model through a server route, keep your connections keys in environment variables, and switch providers without redesigning the interface. For support or community features that do not need a model, the same chat UI works as a straightforward messaging layer.
Protecting the endpoint
Any chat app that calls a paid model needs guardrails. Keep provider keys on the server, rate-limit requests, and validate message length before forwarding. Because the routes are ordinary endpoints, you can add login so only signed-in users reach the model, and log usage to keep an eye on cost. A per-user limit protects both your bill and the experience for everyone else, and running the provider call behind your own server means the key never ships to the browser where it could be copied.
Ship and iterate
Deploy the chat app to a public URL, connect a domain, and watch how people actually converse. Common follow-ups - system prompts, message search, attachments, a feedback button - are all prompt-sized changes on the same project. Real conversations tend to reveal the next feature faster than planning does, so getting a working chat in front of a few users early is usually worth more than another round of design. Each round lands as a version you can compare and roll back.
FAQ
Frequently Asked Questions
Can I use my own AI model?
Yes. Store your provider key as a server-side environment variable and call it from a generated route; BYOB does not force a single model.
Does the chat save history?
It can. Generated apps write messages to built-in data storage or a data source so conversations persist per user.
Is real-time messaging supported?
BYOB generates the interface and data layer; for live updates you can add polling or a socket connection in the code.
Can users log in?
Yes. Add login so conversations are tied to accounts and the model endpoint stays protected.
