Cursor lets cloud agents build and host live web apps

Cursor says you can now build a web app in Cursor and share it with a link. You start a cloud agent and tell it you want to build an app; Cursor then scaffolds the app, spins up a Postgres database if needed, sets up authentication behind Cursor SSO and provisions hosting. When you publish, you pick a unique domain and get a live link. If the app needs to reach your systems, such as a data warehouse, Cursor asks for the secrets it needs.

Cursor says it deploys from new or existing repos on Cursor Origin and GitHub, with other git providers such as GitLab coming soon.

Before an app goes live, Cursor runs deterministic and agentic security checks, for example for secrets written in app files or exposed credentials. Nothing is published until the checks pass and the user explicitly publishes. Team admins can see every app and secret on the team, add their own rules to the review, approve publishes the review blocked, and unpublish any app.

Apps can be shared with specific people, groups or the whole team behind Cursor sign-in; on individual plans they can also be shared publicly. A Cursor API key can be provisioned for a script or Grok Bot to use an app. Cursor says the capability is available on all paid plans with cloud agents enabled, and that its own staff use it for internal tools such as event registration, sales dashboards and onboarding material.
