Cursor cloud agents can build and deploy live web apps with a shareable link
On November 5, 2026 Cursor shipped Build Live Apps: a cloud agent can scaffold a web app, provision Postgres and auth, run security checks, and deploy a live URL after you explicitly publish.
What happened
- Kick off a cloud agent and ask it to build an app; Cursor scaffolds the web app, can spin up Postgres, sets auth behind Cursor SSO, and provisions hosting.
- Publishing requires picking a unique domain, then deterministic and agentic security checks (for example secrets in files or credential files). Nothing goes live until checks pass and you publish.
- Apps can come from new Cursor Origin repos or existing GitHub repos; GitLab support is listed as coming soon.
- Share with people, groups, or the whole team behind Cursor sign-in; individual plans can also share publicly. Team admins can see every app and secret and unpublish any app.
- Available on all paid plans with cloud agents enabled.
Why it matters: People who already use Cursor cloud agents can take internal tools past localhost without a separate hosting workflow, with an explicit publish step and security review before anything is public.
