Built Something in Cursor? Deploy It in 10 Seconds

Cursor makes building apps ridiculously fast. You describe what you want, Cursor writes the code, you iterate until it works. Twenty minutes later you have a working app on localhost.

Then comes the part nobody enjoys: getting it live. Where do you host it? How do people log in? Do you need a database? Environment variables? A domain?

That's where Leash comes in.

One command

Open your terminal in the project directory and run:

leash deploy

Leash auto-detects what you built — Next.js, Express, Flask, Go, Rails, whatever Cursor generated — runs a preflight check, builds it, and deploys it. You get a live HTTPS URL in seconds.

No auth setup

Every app on Leash gets Google sign-in for free. No Clerk subscription. No auth code. No middleware config. Your app reads the authenticated user with one function call:

// Works in any framework Cursor generates
import { getLeashUser } from '@leash/sdk/server'

const user = getLeashUser(req)
// { id: '...', email: '...', name: '...' }

Share it with your team

Send the URL. Your teammates open it, they're already logged in, they can use the tool immediately. It shows up in the Leash dashboard alongside everything else your team has built.

No "can you add me to the Vercel project?" No "where's the link?" No "I can't log in." It just works.

The Cursor + Leash workflow

1. Open Cursor, describe what you need
2. Cursor writes the code
3. Test locally until it works
4. Run leash deploy
5. Share the link with your team

From idea to live app used by your team — in under an hour. That's the promise of AI-assisted development. Leash is the last mile.
