Ship ideas before doubtkills them.
The AI-powered web IDE built for makers who move fast. Write, preview, and deploy — all from one tab. No context switching. No excuses.
Built for the gap between idea and shipped.
Most tools make you choose between speed and power. Dubleu removes the choice — the full stack, from prompt to production, in one place.
AI that writes, refactors, ships.
Describe what you need in plain English. The agent plans, codes, and applies changes directly — no copy-paste, no context switching.
See it live as you type.
WebContainer-powered previews run your actual Node.js app in the browser. Real HMR. Real terminal. Zero latency between edit and reality.
One click. You're live.
Deploy to Vercel or Netlify from the top bar. Custom domains, preview URLs, and env vars — handled. Shipping feels like cheating.
Postgres in seconds.
Provision a Supabase database, run SQL migrations, and wire up auth — all from chat. Your schema lives next to your code.
Ship with your team.
Link projects across your org. Assign cross-project tasks, share previews, and coordinate deploys — without leaving the IDE.
Capture what users actually feel.
Ship the feedback widget with one click. Users annotate screenshots, pin comments on pixels. You see it all in the AI tab — ready to act on.
We replaced three tools with Dubleu. Our first paying user signed up 48 hours after we started building. I've never shipped that fast in my life.
