Cursor can now turn a prompt into a hosted, shareable app
Build Live Apps has a cloud agent scaffold the app, provision a Postgres database and auth, run security checks, then deploy it to a link you choose.
Cursor shipped Build Live Apps on 5 November, letting a cloud agent take a description straight to a hosted app instead of leaving it on localhost. You start a cloud agent and ask for an app; Cursor scaffolds the web app, spins up a Postgres database if one is needed, sets up authentication behind Cursor’s own sign-in, and provisions hosting.
Before anything goes live, deterministic and agentic security checks run against the code, catching things like secrets or exposed credentials. Only once those pass, and you’ve explicitly published, does the app get a link on a domain you pick. Sharing can be scoped to specific people, a group or the whole team, all gated behind Cursor sign-in, or made fully public on individual plans. Team admins can add their own publish rules, approve a blocked release, or unpublish an app outright. It’s available on all paid plans with cloud agents enabled.
Why it matters: this folds the deploy step into the same agent loop as the code, which matters most for prototypes, internal tools and demos that would otherwise die on someone’s machine. It also puts Cursor in the same lane as Vercel and Replit’s agent-to-production pushes, competing on how little infrastructure a developer has to touch.
The caveat: the app lives behind Cursor’s own auth and domains unless you’re on an individual plan going public, so this is a fast way to ship a demo, not a replacement for owning your own deployment.
