    • speedify.exe - main daemon
    • bondingsdk.dll - Speedify SDK Library DLL for communicating with the daemon
    • tap-driver/ - driver and driver installer. Everything in this folder is architecture-dependent
      • TapDriverInstallCheck.exe - driver install manager

  • Link with bondingsdk.lib and put include/ in your include path.


  • Include the contents of the bin/[x64|arm64] folder in your installation path.
    • If you are creating an app that controls a standard Speedify install, you only need bondingsdk.dll
  • Run tap-driver/TapDriverInstallCheck.exe during installation for the architecture you are installing to install the network driver.


  • Run speedify.exe as an admin process or install it as a Windows service.
  • Pass in arguments to the daemon of '-p <port number> -r <installation path> -d <log data path>'.
  • If running as a Windows service, also pass argument of '-s <Service Name>' with the name you installed the service as.
  • In your code, instantiate a CSpeedifySDK object via SpeedifySDK_CreateWithSettings(SpeedifySDK_CreateSettings settings) with the same port you passed to the speedify.exe daemon.
