Cursor Live Apps: Complete Setup (Database + Login)

Cursor Live Apps, tested on my own account: I described an app in plain words, Cursor built it with a Postgres database and a sign-in, and published it to a private live link. Then it broke, the agent fixed it, and its security check blocked a fake secret key I planted. Like Lovable or Bolt, but inside Cursor. What you'll learn - What Cursor Live Apps is, and which plan you need (cloud agents: Premium, $30/month, or higher) - How to build one: the Cursor agents page, Start from scratch, Cursor Cloud - How to publish it: the web address, who can open it, Cursor's publishing terms - Who can open a private app, and what a stranger sees - What broke on the live version, and how the agent fixed it - Whether the security check really stops a secret key Timestamps 0:00 Cursor Live Apps, tested 0:42 What Live Apps does, and the plan you need 1:24 Build an app from a plain request 2:19 Publish it to a live link 2:47 Who can open a private app 3:12 What broke, and the agent's fix 3:45 The security check vs a fake key 4:23 Downsides and verdict Honest trade-offs - It isn't cheap: cloud agents start at Premium, $30 a month. Cursor's pricing page lists no price for hosting your app. - It's slower than the demo: my app took 13m 46s to build (Cursor's demo app: 3m 21s). - My first live version couldn't save anything. The agent fixed it in 12m 35s. - Every build uses your plan's usage, which I didn't measure here. - I tested on my own Super plan. My tests (6 Nov 2026, my own Cursor account) - Build 1, started from the Cursor API with no code folder: 31 min 09 s, and the agent reported that Cursor refused the publish ("This session has no repository attached"). - Build 2, from cursor.com/agents with Start from scratch on Cursor Cloud: worked for 13m 46s, published privately. - The published app showed "The board didn't load" when saving. After the agent's fix (plain web form posts, 12m 35s) an added idea and its vote survived a reload. - I asked the agent to add AWS's documentation example key (not a real one). Cursor's security review blocked that version, and Republish was greyed out.
