  • Jitter: Less than 30 ms from the average latency.

As with any real-time web videoconferencing system, our system will adapt to changing network conditions and resolve minor glitches without harming meeting quality. More severe connectivity glitches may appear as any of the following, and may require additional troubleshooting:

  • Frozen video
  • Low framerates
  • Lower image quality
  • Audio and video out of sync

If you experience issues with poor video or audio quality, you can check-out our Diagnose Your Network with Ping, Traceroute, and Speedtest article for testing and diagnostic suggestions.



Device Minimum Requirements


Desktop and Laptop Computer Hardware

  • Processor: 1.1 GHz Core M
  • RAM: 4GB RAM
  • Microphone
  • Webcam (Not required, but strongly recommended.)


Join by Browser


The quickest and easiest way to join meetings is by using Google Chrome 73 or later, or Microsoft Edge 79 (Chromium-based) or later, on these operating systems:

  • Windows 7 or later
  • macOS 10.9 or later
  • Linux
  • Chrome OS

Due to Chrome security policies, when you use Highfive for the first time, you will need to Accept the addition of the Highfive extension for Chrome.


Several other browsers are based upon Chromium and report themselves as Chrome to web sites. For example, Vivaldi, Blisk, and Brave. Highfive will typically run in these browsers without needing to download the Highfive app, but there may be some inconsistencies or other issues, and these browsers are not officially supported at this time. To avoid problems, we recommend using the latest version available of your browser.


Join by the Highfive App


If Google Chrome is not available, you can use the Highfive app on Windows or macOS instead.
