Cursor's Build Live Apps Turns a Prompt Into a Hosted Web App

Nothing here is sponsored — no affiliate links on this page. This breaking article is not the daily buyer-intent post. Facts below come from the sources listed at the end, checked 6 November 2026. We have not tested Build Live Apps hands-on, and nothing here is a hands-on finding.

Cursor shipped Build Live Apps on 5 November 2026, and it changes what Cursor is. You describe the app you want to the cloud agent, and it builds it, wires up a Postgres database if the app needs one, puts login behind Cursor SSO, hosts it, and hands you a link you can share.

I have watched this exact pitch from Lovable and Replit for a while now. The difference here is where it lives: inside the editor developers already spend their whole day in. Cursor stopped being just the place where code gets written. Now it wants to be the place where the thing gets shipped too.

What it actually does

The flow, as Cursor describes it in the changelog, is short:

• You tell the cloud agent what to build, in plain words. It writes the app, and sets up a Postgres database when the app needs one.
• Login comes from Cursor SSO, so you are not wiring up auth yourself.
• It hosts the app and runs security checks on it.
• You get a shareable live link — but only after the checks pass and you publish it yourself.

That last point matters more than the rest, and it gets its own section below.

A few boundaries worth knowing up front. This only works from the cloud agent, not the local agent in your editor. A new app starts in a repo on Cursor Origin, Cursor's own hosting for this, or you can deploy an existing GitHub repo. GitLab support is listed as coming soon, which is the polite way of saying it does not exist yet.

The part I actually like

Nothing goes live by itself. An app stays unpublished until it passes both deterministic and agentic security checks, and then you still have to publish it yourself. Admins can see every app and every secret in their workspace, and they can unpublish anything.

That is a real design choice, not a footnote. The vibe-coding tools that came before this made shipping so easy that people shipped database credentials and open admin panels by accident. Cursor looked at that failure mode and put a gate in front of it. The gate will annoy someone, eventually, when a check blocks a deploy they were sure was fine. That is the point of a gate.

I have not run Build Live Apps myself, and I am not going to pretend otherwise. Everything above is what Cursor published and what the early coverage reports. The honest review — the one where someone builds a real app, hits the rough edges, and finds out what breaks at 2 a.m. — does not exist yet.

Who this is for, and who should wait

• If you already live in Cursor and you prototype constantly, this is the most interesting thing Cursor has shipped in a while. The loop from "I have an idea" to "here is a link, try it" no longer leaves the editor. For internal tools, demos, and hackathon-style builds, that is a genuine time saver.
• If you build client work or anything with real user data, wait for the answers in the next section before you put anything serious on it. The security gate is reassuring, but a gate is only as good as what it checks, and nobody outside Cursor has stress-tested it yet.
• If you are on the $8 Plus plan, this is not for you at all — Plus does not include the cloud agent. Build Live Apps is on the paid plans where the cloud agent is available, starting with Premium at $30 a month.

What we still don't know, and it is the part that decides everything

• Hosting price. Cursor has not said what hosting costs beyond the plan, or whether there is a usage-based charge on top. As of 6 November, nothing.
• Quotas and limits. How many apps, how much traffic, how much database storage — unpublished.
• Backups and getting your data out. No published answer on backups, or on how you export your app and your data if you decide to leave.

Those three questions decide whether this is a tool you build on or a demo you play with for a weekend. A hosted app you cannot back up or export is a hostage situation with good branding. I am not saying Cursor will trap anyone — I am saying nobody can verify otherwise until they publish the answers.

Every number in this article that comes from Cursor is labeled as Cursor's claim, because that is what it is. No prices, no limits, and no performance figures beyond the verified facts above have been invented to fill the gaps.

The bottom line

Cursor's move makes sense on its own terms. Lovable and Replit proved people want prompt-to-live-app; Cursor is betting its users would rather do it without leaving their editor, with a security gate in front of the publish button and SSO handling the login. That is a reasonable bet, and the gate is the most grown-up part of the whole launch.

But a hosted app is a commitment, not a demo. Until Cursor publishes the hosting price, the quotas, and the exit path for your data, the smart move is to build something small on it, see how the gate behaves, and keep the serious stuff where you already host it.

So here is my question: if you use Cursor, would you ship a real app through it today — or does the missing pricing and export story keep you waiting? I am genuinely curious where the line is for you, because that is the decision this launch is really asking you to make.
