How to use Cursor to Cursor Live Share

Cursor's Live Share feature enables seamless real-time collaboration between developers, allowing multiple users to view and edit code simultaneously. This guide provides detailed instructions on setting up and using Cursor Live Share effectively.

Introduction to Live Share Feature​

Cursor Live Share is a powerful collaboration tool that enables real-time code sharing and editing between multiple developers.

      • Read-only: Participants can only view files
      • Read/write: Participants can view and edit files
      • Full access: Participants can view, edit, and execute commands

Joining a Live Share Session​

  1. Receive an invitation link from the host

  2. Open the link:

    • Click on the link you received
    • Cursor will automatically launch and connect to the session
    • If Cursor doesn't open automatically, copy the link and paste it in Cursor's command palette with the command "Live Share: Join collaboration session"

  3. Wait for connection:

    • A notification will appear when you're successfully connected
    • The shared workspace will open in a new window

  4. Verify your permissions:

    • Check the Live Share status bar to see your access level
    • Request additional permissions from the host if needed

Managing Shared Sessions​

Effective session management ensures a smooth collaboration experience for all participants.

Host Controls​

As a session host, you have several controls to manage the collaboration:

  1. Monitor participants:

    • Click on the Live Share icon in the status bar
    • Select "Show Participants" to see who's connected
    • View each participant's cursor position and current file

  2. Manage permissions:

    • Change access levels for individual participants
    • Revoke access for specific participants if needed
    • Lock the session to prevent new participants from joining

  3. Focus requests:

    • Send "Follow me" requests to direct participants to your current file
    • Accept or decline "Follow me" requests from participants

  4. End the session:

    • Click on the Live Share icon
    • Select "End Collaboration Session"
    • All participants will be disconnected

Participant Controls​

As a participant in a Live Share session, you can:

  1. Navigate independently:

    • Browse through the shared workspace
    • Open and view files (edit if you have permission)

  2. Request focus:

    • Ask the host to follow your cursor
    • Click on the Live Share icon and select "Request Follow"

  3. Chat with other participants:

    • Use the integrated chat panel (if available)
    • Share code snippets and links

  4. Leave the session:

    • Click on the Live Share icon
    • Select "Leave Collaboration Session"
    • Your connection will be terminated without affecting others

Security Considerations​

When using Live Share, it's important to consider security implications:

Access Control​

  • Share only with trusted collaborators: Be cautious about who you invite
  • Use read-only access when full editing capabilities aren't necessary
  • Regularly review connected participants during long sessions
  • End sessions when collaboration is complete

Data Protection​

  • Avoid sharing sensitive credentials during Live Share sessions
  • Be mindful of environment variables that might be exposed
  • Consider excluding sensitive files from being shared
  • Use secure channels to share the invitation links
