Build Live Apps

Build Live Apps is the Cursor capability announced in the 2026-11-05 changelog: cloud agents take an app from prompt to a shareable live URL, not just localhost. Official: https://cursor.com/changelog/build-live-apps .

Flow (official):

1. Start a cloud agent and say you want to build an app;
2. Scaffold the web app; spin up Postgres if needed;
3. Configure Cursor SSO auth and hosting;
4. Ask for secrets when connecting warehouses / internal systems;
5. Run deterministic + agentic security checks before publish (e.g. secrets in files); nothing goes live until checks pass and you confirm;
6. Pick a domain, get a live link; share to people/groups/org — individuals can also publish publicly.

Deploys from new or existing repos on Cursor Origin / GitHub (GitLab later). Team admins see every app and secret, add review rules, approve blocked publishes or unpublish.

Why it matters

After codegen got cheap, the bottleneck is often ship / auth / DB / share. Build Live Apps productizes that path so sales, ops, legal and finance can self-serve internal tools inside the org.

Peers

v0, Replit Agent and other hosted agents also generate-and-host; Cursor's version sits inside the IDE + Cloud Agents + SSO/org controls, with an explicit pre-publish security gate.

Limits

• Needs a paid plan with Cloud Agents;
• Governance still depends on admin rules and secret hygiene;
• Heavy enterprise compliance (audit evidence, etc.) is on you.

Who it's for

• Cursor Cloud Agent teams that want non-engineers shipping internal tools;
• Buyers who need SSO + admin visibility for internal apps;
• People comparing against persistent-agent products like Kiro bots.

Getting started

1. Update Cursor; confirm a paid plan with Cloud Agents;
2. Read https://cursor.com/changelog/build-live-apps and the docs;
3. Start a cloud agent and explicitly ask to build/publish an app;
4. Pass security checks, pick a domain, share with the team or provision an API key for scripts/Grok Bot.
