What Dubleu can do

Your whole dev workflow, in one place

From blank canvas to deployed product — Dubleu handles every step so you can focus on what you're building, not how you're building it.

AI that writes real code

Chat with Dubleu and it writes, edits, and refactors code across your entire project. Agent mode runs multi-step tasks autonomously — plan, code, deploy.

Live preview in the browser

Your app runs in a real Node.js environment inside the browser via WebContainers. See changes instantly — no local setup, no Docker, no headaches.

One-click deploy

Deploy to Vercel or Netlify straight from the chat. Every project gets a free subdomain. Custom domains managed right inside the IDE.

Database & auth, instant

Provision a Supabase database, run SQL migrations, and wire up auth — all from chat. Credentials stored securely, injected automatically at deploy.

Blueprint & Canvas mode

Ask Dubleu to draw a wireframe before writing a line of code. Or generate live architecture diagrams and ER diagrams rendered directly in the editor.

Connect any tool

MCP integrations for Stripe, GitHub, Linear, Slack, Supabase, and more. Your AI IDE plugs into your whole workflow — not just your code.

How it works

From idea to live in minutes

No boilerplate. No config hell. Just describe, build, and ship.

01

Describe what you want to build

Type your idea in plain English. Dubleu's AI understands context, asks the right questions, and draws a visual blueprint before writing a single line of code.

02

Watch it build in real time

Dubleu writes code across every file, runs the app live in the browser via WebContainers, and shows you a working preview — all without leaving the editor.
