If you are having trouble running Kosy on your device or browser, it is possible they are not fully supported by Kosy. Following devices and browsers are supported.

Operating Systems:

  • Mac OSX with Mac OS 10.10 or higher

  • Windows 7 or higher


  • Chrome (latest 2 versions) - Recommended for most stable connectivity

  • Edge (latest 2 versions)

The platform is found to often work on Linux systems and mobile devices as well - but they are not currently officially supported.

If you are sure your OS is supported and it still has trouble running Kosy, it may not have the system requirements needed to run Kosy.

Kosy office runs in a browser, so the system requirements reflect the basic usage of the browser itself + the additional use of Kosy - assuming Kosy is the only application running on the open browser. As browsers make changes to how they work, these requirements are subject to change outside of our influence.


  • Minimum: 1.5GB of freeable memory.

  • Recommended: 2.5GB of freeable memory


  • Minimum: 2.2 GHz dual core i5

  • Recommended: 2.8 GHz quad-core i7


  • Webcam, microphone and audio output devices must be compatible with browser used
