Check_MK is available in three different editions:

  • The free Check_MK Raw Edition (CRE) - a comprehensive IT monitoring system, immediately available for download and 100% open-source
  • The extended Check_MK Enterprise Edition (CEE) - for use in professional environments with many additional features & increased performance
  • The Check_MK Managed Services Edition (CME) - for managed services providers as the name already implies
  • The virtual appliance for the use within an existing virtualization platform

You can download the Raw Edition (CRE) right away. A subscription is required for the download of the Enterprise Edition (CEE) and Managed Services Edition (CME).
If you want to try out the Enterprise (CEE) or Managed Services (CME) edition, you can download the demo versions listed below. Keep in mind though, the demo versions don't have any limitations, but instead throw random errors.
Please also read our article on Check_MK version numbers and the migration notes.
