Here you can download the latest versions of code for both your hardware and software. In addition you'll find the design files for the Ultracortex 3D-printable EEG headset. Don't know what any of this means? That's ok too! Check out our Getting Started Guide and other reference material.

OpenBCI GUI · v5.0.0
Here you can download the standalone OpenBCI Graphical User Interface (GUI) for your operating system. It is the easiest and fastest way to connect to your OpenBCI hardware, visualize physiological data, and stream it to other applications and tools.

If it’s your first time working with OpenBCI and you own the Cyton or Cyton+Daisy, make sure to install the latest FTDI driver for your operating system. This installation is required to establish a clean connection with the OpenBCI Cyton and Cyton+Daisy hardware.

If you want to work with older versions of the OpenBCI GUI, head to our Github Repository to see all previous releases of the OpenBCI GUI.

Mac OS X Catalina users and System Administrators: Please allow the GUI to access the web to check for updates and allow access to users' Documents folder.
