Postgres built in·11 stacksOne-click deploy·Custom domains
SpinBuild writes the frontend, backend and Postgres database from your description, then deploys it all to a live URL or your own domain in one click, with the code in a GitHub repo you own.
Your idea. Your stack.
11 supported stacks. From your first website to a full-stack app or backend service, choose what fits your idea and start building.
Frontend libraries, full-stack frameworks, and backend tools. Real source code in the stack you choose.
The facts
SpinBuild is an AI development platform for vibe coders and developers. Describe a website or app, choose your stack and AI model, and iterate with a live preview. People who don't write code get changes applied automatically. Developers accept or reject each diff. Sync with GitHub and publish over HTTPS.
Our team is working on continually improving a development workflow that brings prompting, code review, live previews, private Postgres, GitHub sync, and publishing together.

Who it's for
You don't need to write code to start, and you can still read every line if you do.

The short version
SpinBuild turns a description into a live app: you describe it, review the diff, and deploy it to an HTTPS URL.
THE PROMPT
Your words. The starting point.
THE CONTROL
Apply changes automatically or review the diffs.
THE LAUNCH
One deploy. A live URL. All yours.
Every model, one dropdown
GPT-6.1 Sol is our recommended starting point for building, and it is included on the free plan. Claude Opus 5.5, Claude Sonnet 5.5, and the rest of the catalogue are on paid plans. Choose a model and compare its current context window and pricing.

You're in charge
Changes land in your preview as you go, so you judge the thing itself rather than a diff. Nothing reaches the public until you press Publish — and every version is one click away if you want to go back. If you'd rather approve every edit first, turn review on in Settings and SpinBuild waits for you, file by file.
Watch each change appear in the live preview.
Jump back to any earlier version, any time.
Developers: switch review on for diffs and per-file accept.

The whole thing
SpinBuild builds a complete app from the first prompt: the interface, the backend, and a Postgres database, running live in its own space. You can keep that database on SpinBuild, or Continue with Supabase on your own account. The preview is the real app, not a mockup.
Interface, backend, and database together.
A real Postgres database for every project.
Continue with Supabase if you want that Postgres on your account.
A live preview that's the actual app.

It keeps up with you
SpinBuild streams the code as it writes it, and the preview updates when you accept a change. You see the new version on the preview before anything is published.
AI responses stream in as they're written.
Your preview refreshes the instant you approve.
Everything stays in sync, moment to moment.

From build to live
On a paid plan, SpinBuild syncs your project with a GitHub repository you own, both ways. Your changes are pushed up, and commits made on GitHub, by you or a teammate, are pulled back in while the project is open. Publishing to an HTTPS URL is one click, and the code uses your selected stack and can run elsewhere with the appropriate dependencies and hosting.
Two-way sync with a repo you own.
One-click deploy to a live HTTPS URL.
Your code, yours to keep.

Try asking your assistant
“Find my booking project, inspect its form, and add date validation. Show me the changes before pushing to GitHub.”
List projects, inspect files, and let your assistant write changes directly to your SpinBuild project.
File edits sync to an already-running preview. Open SpinBuild to inspect the app as you iterate.
Check recorded production build logs and push changes through your connected GitHub account.

Remove the old SpinBuild server from your client and add it again using this setup. Old Authorization headers or bearer-token settings prevent the browser sign-in flow from starting. Your projects are kept in SpinBuild.
Real apps, not just pretty pages
From your very first message, SpinBuild builds the whole thing: what people see, what happens when they click, and where the information is saved.
Every app gets its own private database, set up automatically. One app can never see another’s data.
Publish to your-app.apps.spinbuild.ai over a secure connection. Your own domain on paid plans.
What you see is your actual working app, not a mock-up. Click around and try it.
Every change is saved as a version you can go back to at any time.
Your app’s visitors can sign in with email and password, Google, GitHub or LinkedIn — no setup.
Send your preview link to friends, clients or teammates to get feedback first.
Built-in analytics for your live site and preview: visitors, pages, referrers, countries and devices.
Each app runs in its own locked-down space, so nothing else can affect it.
Your code, your GitHub, your database — always yours. Take it anywhere you like.
How it works
The same simple process works for your first idea and every change after it.
Describe your idea in your own words. SpinBuild plans the pages, the logic and the data before it starts.
Build an invoicing app for my agency: clients, invoices with line items, PDF export, and a dashboard of what's overdue.
Your app shows up in a live preview and updates as you ask for changes. Every version is saved, so you can return to an earlier one at any time.
Press Publish and your app goes online with its own secure web address. Nothing goes public until you say so.

FAQ
Pick what fits you best, and we'll show the answers that matter to you.
Sign up with email, Google, or GitHub, choose a supported stack, and describe what you want to build. SpinBuild generates the project and lets you work with a live preview in your browser. Starter is free with no credit card; paid plans provide larger allowances.
No. You can start by describing what you want, checking the preview, and asking for changes. Coding knowledge helps with more complex requirements and troubleshooting. If you write code, you can inspect the source and diffs in your selected stack and connect your GitHub repository.
SpinBuild is an AI platform for building websites and web apps from plain-language descriptions. Choose your stack and AI model, generate and refine your project with a live preview, and publish it to a live URL. Private Postgres is available for app data, and optional code review lets you inspect changes as diffs.
Vibe coding means describing the software you want instead of writing every line yourself. In SpinBuild, you describe changes, inspect the running preview, and refine the result. You can enable code review to inspect diffs before accepting changes.
