Cursor Lets You Build Live Apps and Share Them With a Link
You can now build live apps in Cursor and share them with a link. Agents have made it easier to write code, but most apps never make it off localhost. Describe the tool you want - Cursor will build it, set up a database, run deterministic and agentic security checks, and deploy.
Context
Turning agent written apps into shareable live deployments, with database setup and security checks included, shrinks the gap between a localhost demo and something others can use.
Cursor (@cursor_ai) is an AI coding editor. On Nov 5 the company said users can build live apps inside Cursor and share them with a link. According to the post, Cursor will build the tool, set up a database, run deterministic and agentic security checks, and deploy, aiming to move apps past localhost.
Deep dive
Cursor (@cursor_ai) posted on Nov 5 that users can now build live apps in Cursor and share them with a link. The company said agents already make writing code easier, but most apps never leave localhost, and that Cursor will build the requested tool, set up a database, run deterministic and agentic security checks, and deploy.
If the flow works as described, it is a product step from code generation toward hosted, shareable tools. Database setup and security checks in the same path matter because those are where many agent demos stall. The post does not list pricing, regions, language support, or which security checks are automatic versus optional.
This lands in a crowded agents and coding tools race with OpenAI Codex, Claude Code, Devin and others. A one click share link is a distribution play: teammates and clients can try an app without cloning a repo. The security claim will be tested quickly if shared apps are abused or misconfigured.

What to expect next
Watch for docs on the security checks, hosting limits, and whether shared apps stay up under real traffic. Competitors may ship similar share links soon. Enterprise buyers will ask about data residency, secrets handling and audit logs before allowing staff to deploy from chat. Abuse reports on shared apps will show how strong the checks are in practice over the next weeks.
