Build working apps, websites, and AI agents by describing them
Describe an idea and get a working app with database, authentication, payments, and hosting already wired up — no server or infrastructure setup.
Generates complete websites with layout, copy, and design, plus built-in SEO tools and custom domain support, ready to publish in one click.
Create 24/7 AI agents that connect to your tools, take real actions, manage data, and automate recurring workflows autonomously.
Connects to Google Calendar, Gmail, Slack, Notion, HubSpot, Salesforce, and more, with API access for anything else you use.

Combine all your computers into one supercomputer for you and your agents
Turn the computers you own into as many lightweight desktops as they can hold, listed in one place and streamed to you as live desktops.
An MIT-licensed driver that lets agents use native desktop apps on macOS, Windows, and Linux without taking over your cursor or keyboard.
Move an app's session bundle — open tabs, profile, sign-ins — from your Mac into a Space, with approval and Touch ID gating sensitive items.
Run Spaces on your Mac, on machines you own, or in your own cloud account; Cua provides the app, sharing, and relay, not the hardware.
