Cursor: Repo-Free Cloud Agents with Live Preview and Vercel Publishing

CursorView original changelog

Cursor removed the requirement for a connected GitHub or third-party source-control provider before starting a Cloud Agent. Developers can now prompt an agent from a blank slate, and Cursor automatically provisions a Cursor Origin repo behind the scenes to hold the work. The release also adds a live browser preview of the agent's running environment via port-forwarding, plus one-click Vercel publishing to get a shareable live URL once the build is ready.

Key Takeaways

  • No repo, no problem — Cursor's Cloud Agents can now be prompted from a completely blank slate, removing the prior requirement to connect GitHub or another SCM provider first.
  • Cursor auto-creates an Origin repo in the background as the agent works, so nothing is lost even before the developer decides to formally save it.
  • The "Create repo" button lets developers name the repo (or accept a suggestion) and choose private or internal visibility once they're happy with the result.
  • A new live browser preview port-forwards the agent's running environment directly into the browser, enabling tools like design mode against the live app.
  • Vercel publishing is built into the flow — connecting a Vercel account and hitting publish produces a live, shareable URL straight from the agent session.
  • This feature deepens Cursor's push toward Origin as the native home for agent-generated projects, following Origin's broader beta launch on August 17, 2026.

Starting Without a Repository

Cursor's Cloud Agents previously required a connected GitHub or other third-party source-control provider before an agent could begin working. That requirement is now gone. Developers can select "Start from scratch" in the repo picker and prompt the agent immediately, with no pre-existing codebase or repo connection needed.

Behind the scenes, Cursor automatically creates a Cursor Origin repo to hold the agent's work as it progresses. This lets developers go from a blank prompt straight to a running project without first setting up version control, which is particularly useful for quick prototypes, throwaway experiments, or greenfield projects where the repo doesn't exist yet.

Saving Work to an Origin Repo

Once the agent's output looks good, developers can click "Create repo" to formally save the work into a Cursor Origin repository. At that point, they can choose a custom repository name or accept one of Cursor's suggested names, and set the visibility to private or internal. The result is a fully scaffolded Origin repo, ready to share with teammates or continue building on with further agent sessions.

This workflow ties directly into Origin, Cursor's native code-hosting platform introduced earlier in August, giving repo-free agent sessions a natural home once they're worth keeping.

Live Preview and Publishing

Cursor now port-forwards a cloud agent's live running environment directly into the browser, so developers can preview what the agent built in real time and use tools like design mode against the live app rather than only reading code or logs.

For projects ready to go live, connecting a Vercel account lets developers hit publish directly from the agent session to get a working URL, closing the loop from prompt to deployed project without leaving Cursor.
