Describe an app.
Ship it on Cube.
Cube Studio turns plain-English ideas into real web and mobile apps — then deploys them zero-rated to the Cube Browser and the Cube App Store. No build tools, no servers, no setup.
Free · macOS, Windows & Linux
From idea to live app
Build it by talking. Ship it for free.
Cube writes the whole project, keeps a live preview running, and publishes it zero-rated — whether or not you write code.
Plain English in, real apps out
Describe what you want and Cube writes the whole project — every file — with a live preview that builds as you watch.
Web and mobile, one flow
Ship responsive web apps to the Cube Browser and phone-first apps to the Cube App Store. Pick a target, or let Auto decide.
Zero-rated by default
Cube pays for the data. Everything you publish costs your users nothing in mobile data — with nothing extra to configure.
Polished, every time
Every app is composed into the frozen Cube App Kit, so it looks consistent and ship-ready without any design work.
The Agent, building live
From a sentence to shipped — in seconds.
Type your idea and Cube writes a complete project — not just one file — streaming each file as it is created, with a live preview beside the chat.
Two ways to build
Talk to it, or take the wheel.
The Agent and the Editor share the same AI — pick whichever fits the moment.
The Agent
Describe your idea in everyday words. Cube handles the code, design, and deployment — you never have to touch a file. Chat on the left, a live preview on the right.
- Builds the whole project from one prompt
- Live browser or phone-frame preview
- Refine by chatting — “make it warmer”
The Editor
A full IntelliJ-style workspace: file tree, tabs, terminal, and Monaco code editing — with a docked Cube AI panel. Steer the build file-by-file and ship.
- File tree, tabs & a working terminal
- Monaco editor with a Run cluster and live URL
- Mix hand-edits and AI edits freely
How it works
Idea to live app in four steps.
Describe
Tell Cube what you want in plain English — the purpose, the sections, and the vibe.
Generate
Cube plans the project, writes every file, and a live preview appears as it builds.
Refine
“Make the header sticky”, “add a dark theme.” Each change applies and the preview reloads.
Publish
Go live zero-rated — a cube:// link in the Cube Browser, or a listing in the App Store.
The Cube promise
Zero-rated, so your users pay nothing.
Cube covers the data for everything you publish. People can open and use your app without it touching their data allowance — and there is nothing extra for you to configure.
For your users
Open and use your app without it eating their data.
For you
Every app you publish is zero-rated by default.
Data stays free
Remove the cost barrier so more people reach you.
Remembers data
CubeStore persists entries, settings and progress — no database to set up.
