On November 5, 2026, Cursor launched a build-live-apps feature: without leaving the editor, you describe what you want to a cloud agent, and it builds the app, sets up a database, wires up authentication, and deploys it, handing you a link you can share. It moves Cursor's cloud agents from "help you write code" to "help you ship something that actually runs".
From one sentence to a live app
The flow has four steps. First, start a cloud agent and tell it explicitly that you want to build an app. Second, the agent scaffolds the app and spins up a Postgres database if one is needed. Third, authentication is wired up through Cursor SSO; if the app needs to connect to internal systems such as a data warehouse, the agent asks for the secrets it needs. Fourth, when you publish, you pick a unique domain and the app is deployed to that address once the checks pass, with access controlled by your team. Repos can be new or existing ones on Cursor Origin or GitHub; GitLab support is still on the way. Built on the existing cloud agent capabilities, this extends "writing code" into "delivering a usable product".
Two gates stand before anything goes live. At publish time, deterministic checks and agentic security checks run first, catching common problems such as secrets written into app files or exposed credentials; a failed check has to be fixed before publishing. Team admins can also see every app and secret on the team, add their own rules to the security review, approve publishes the review blocked, or unpublish an app. On individual plans, apps can be shared publicly as well.
The examples Cursor gives are very much "internal tools": event registration, desk seating, sales dashboards, customer presentations, new-hire onboarding, engineering service portals. In other words, the feature targets the lightweight tools every team wants but can never get onto the engineering roadmap. The limits are clear too: it is only available on paid plans with cloud agents enabled, and it only gets the app running — it does not guarantee the business logic is right on the first try, so complex systems still need human review. For teams that want to try it, the cheapest way to validate is to update Cursor to the latest version and have a cloud agent build one small tool.
