This tool was built to facilitate Multiplayer development experience. It allows unity to launch the same project multiple times within the editor to avoid re-building for every modification.


Features include:

  • One-click setup
  • Lightweight client of less than 1MB when Link Library is checked
  • Launches the right Unity Editor version for each project
  • Remembers client details after closure
  • Efficient AutoSync only when the original project scene is saved
  • Unlimited client count; initially capped to 20 but can be easily modified to allow for more
  • Complete control over each client independently
  • Clients can be grouped by selecting the same storage location
