Cursor announced the Live Apps feature in its changelog on 5 November. Most apps that users build stay on the developer’s own machine, where no one else can use them, the company said.

How publishing works

The user starts a cloud agent, a coding agent that runs on Cursor’s servers, and explicitly asks it to build an app. Cursor said the agent scaffolds the app, creates a Postgres database if needed, puts the app behind Cursor single sign-on (SSO) and provisions hosting. To publish, the user chooses an address and receives a link. The code can live in a new Cursor Origin repository or on GitHub, and GitLab support is coming, the company said.

Before publishing, Cursor runs rule-based and agent-run security checks. These look for secrets written into app files, among other things. Nothing is published until the checks pass and the user publishes the app themselves, the company said. Team administrators can add their own rules to the checks and approve blocked publishes. The 7minai guide site says Cursor’s documentation excludes blocks caused by malicious code, secrets written into code or exposed credentials.

Apps can be shared with specific people, groups or the whole team. Anyone using the app must then sign in to Cursor. On individual plans, apps can also be shared publicly. The same guide says the documentation states that hosting is provided as is and that a published app can be disabled.

In testing, the first version saved no data

Mervin Praison, who makes videos about AI, tested the feature on a personal account on 6 November. Praison’s idea-voting app took 13 minutes 46 seconds to build. A different app in Cursor’s demo video took 3 minutes 21 seconds. The agent said Cursor had refused to publish an earlier attempt, which had been started through the API without a repository.

The published app saved nothing. The agent fixed the bug in 12 minutes 35 seconds by switching saving to plain web forms. The explanation comes only from the agent, which said Cursor’s server had rejected the original saving method. Praison advises testing the published link, not just the preview.

When the agent added an example key from AWS’s documentation to the app, the security check blocked publication. The check only warned about a risky software library. These results come from one user’s tests.

Voice chat and availability

Cursor also released voice chat on 6 November. Users can talk with the agent in a real-time voice call and hear short status updates as the work progresses. The feature is based on Grok Voice and works in the editor, on the web and in the iOS app. Cursor said conversation data is not retained when privacy mode is on.

Cursor said Live Apps is available on all paid plans with cloud agents enabled. Praison said Cursor’s pricing page includes cloud agents in the Premium plan at $30 a month and in more expensive plans, but not in the $8 Plus plan. The pricing page does not list a price for hosting. Building draws on the plan’s usage limit, but Praison did not measure how much.
