Cursor lets users build, deploy and share live apps from its editor

From localhost to a live app

Cursor says most apps and tools built by users never move beyond localhost. Its latest release is designed to take those projects through development and deployment in the same workflow.

Users begin by starting a cloud agent and explicitly telling it to build an app. Cursor then scaffolds the web app, creates a Postgres database when one is needed, configures authentication through Cursor SSO, and provisions hosting. If the app must connect to an external system, such as a data warehouse, Cursor will ask for the required secrets.

When the user is ready to publish, they choose a unique domain and Cursor returns a live link. The company says users in sales, operations, legal, finance, and engineering are already building internal applications with the capability.

Internal tools, dashboards and customer experiences

Cursor lists several examples of applications being built by its users. These include internal operations tools for event registration, account assignments, and desk seating, as well as multimedia presentations that combine slides, videos, and interactive demos.

Other examples include training, enablement, and onboarding experiences for new hires; live dashboards and tools for sales teams to understand their pipeline and opportunities; and portals for managing engineering services.

Cursor can deploy applications from new or existing repositories across Cursor Origin and GitHub. The company says support for other Git providers, including GitLab, is coming soon.

Security checks and team controls

Before an application goes live, Cursor runs deterministic and agentic security checks intended to catch common problems such as secrets stored in application files or exposed credentials. If a check fails, the agent tells the user what needs to be fixed.

Cursor says an app cannot go live until the checks pass and the user explicitly publishes it. Team administrators can view every app and secret on the team, add rules to the security review, approve publishes blocked by the review, and unpublish applications.

After publishing, users can share an app with specific people, groups, or their entire team, with access protected by Cursor sign-in. Individual plans also allow public sharing. A Cursor API key can be provisioned for a script or Grok Bot that needs to use the app.

Availability for paid plans

The live app capability is available now on all paid plans with cloud agents enabled. Cursor tells users to update the product to try it. The release gives organizations a path from a natural-language description to a hosted internal tool, while keeping deployment, access, and security review inside Cursor's workflow.
