App Development Platform
an app development platform should carry a product from first description to running publishing, not stop at a clever demo. BYOB pairs AI generation with an editable codebase, managed data storage and publishing, so the same workspace stays useful as requirements harden.

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.
- Approve project access from BYOB
- Installs the byob command
- Preview, deploy, git diff, DNS, credits, and code tools

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.
- Vision inputs
- Voice coding
- Project templates
- SEO-ready output
- Context tracking
- Model lock

an app development platform is the environment where an application is generated, extended and shipped. BYOB turns a written brief into a working project, then keeps the source, data and publishing reachable in one place, so teams move from prototype to production without switching tools or losing ownership of the code.
A platform is more than a one-shot generator
Many tools generate a screen and then leave you to assemble the rest. A platform keeps working after the first output: it remembers the project, understands the schema, and lets each new request build on the last. That continuity is what turns an idea into a maintained product. With BYOB, the description you gave on day one still informs the changes you make in month three, because the assistant reads the existing routes, components and data model rather than starting blind each time.
The whole lifecycle lives in one place
Consider the stages a small product passes through: define the workflow, generate the interface, add login, model the data, connect payments, preview, publish, then iterate. Doing that across five subscriptions creates handoff friction and stale documentation. BYOB folds those stages into a single project, so a change to the data model is reflected in the screens that read it and the publishing that serves it, without an export-and-import step between each tool.
Engineered for handover
Platforms fail teams when the person who started the project leaves. BYOB keeps a real version control repository behind every project, with commits you can diff and revert, plus a browser editor for reading the source. A new developer can clone the workspace, understand the structure and continue, rather than reverse-engineering a proprietary configuration file. That makes the platform safe for agencies, internal teams and founders who expect to bring in help.
Extensible, not sealed
A capable platform admits what it does not do. BYOB connects to external services such as a data source for teams with an existing backend, exposes an and an agent for local workflows, and supports built-in payments for payments. When a requirement is genuinely specialised, you are not blocked; you open the route and write it by hand. The platform accelerates the common case without capping the uncommon one.
How to judge a platform fairly
Weigh four things: what the output is, how portable it is, what the running costs become, and what happens at the edges. Ask whether you get standard code or a hosted black box, whether you can export and self-host, whether pricing is transparent, and how the tool behaves when your need falls outside its happy path. BYOB answers those with output, and ZIP export, published plans, and a manual coding route when generation is not enough.
FAQ
Frequently Asked Questions
What should an app development platform include?
At minimum: generation, editing, data storage, login, preview and publishing. BYOB adds version control, export and integrations so the project survives contact with real requirements.
Is this only for people who cannot code?
No. Developers use it to skip boilerplate, then edit the source directly, run it locally through the and manage it with version control.
What framework does BYOB generate?
with and Tailwind. If your organisation standardises on another framework, that constraint is worth weighing first.
Can a team collaborate on one project?
Yes. The project lives in a shared workspace with version history, so changes are traceable and reversible across contributors.
Can I leave the platform later?
Yes. Projects export as standard code through the or a ZIP download, with no proprietary runtime required to run them.
