The browser studio
An AI app builder online, nothing to install
Open a tab and build: sketch screens, connect your data, watch the preview follow you. When it looks right, launch it on your own domain.
Free to build for as long as you like.
Asset needed
Capture from bb dev run studio: the studio mid-build with screens, data, and the live preview visible together. 1440x820 at 2x, aspect-video.
From blank tab to live app
Describe or sketch
Start from your idea in plain words, or from a working example you make yours.
Shape it as you watch
Screens, data, and logic sit side by side, and the preview updates as you work.
Launch when ready
Your first live app is free, custom domain and HTTPS included.
An AI app builder online with a real backend
The tab holds the whole builder: a real Postgres backend, sign-in for your users, and a path to launch. The laptop you have is enough.
Questions, answered
Do I need to install anything?
No. The studio runs in your browser; the CLI and desktop app are optional extras.
What does it cost to try?
Nothing. Building is free, and your first live app is free with a custom domain.
Can AI do the building?
Yes, when you ask. AI work draws from a prepaid balance, 1 credit = 1 dollar, or bring your own Claude or ChatGPT subscription.
What happens when I close the tab?
The app stays. Everything is saved as you work, and the same app is there when you come back, from any surface.
Start in the tab you already have open
By tonight the idea could be an app with your name on the domain.
Free to build for as long as you like.
