Cursor lets cloud agents build, host and publish live web apps

On November 5, 2026, Cursor announced in its Cursor changelog that its cloud agents could build, host and publish live web apps, in an entry titled Build Live Apps in Cursor.

How it worked

• A cloud agent built the web app, added Postgres when needed, wired up login through Cursor SSO and provisioned hosting with a shareable link.
• Going live required passing automated security checks, for example for secrets left in app files, plus an explicit publish step.
• Team admins could see all apps and secrets, add review rules, approve blocked publishes and unpublish any app.
• Apps could be shared with chosen people, groups or the whole team behind Cursor sign-in, and public sharing was for individual plans.

What it meant for people building with AI

Cursor users could go from a prompt to a hosted internal app without setting up their own database, authentication or hosting. The security checks and the explicit publish step put a gate between an agent's output and a live link, and the admin controls let teams review and remove apps.

Availability

The feature was available on every paid plan where cloud agents were enabled. Deploys came from Cursor Origin or GitHub repositories, with GitLab support listed as planned.
