System Requirements


Operating System

  • Ubuntu 20.xx, 22.xx
  • CentOS/Red Hat Enterprise Linux 8.x

Countly does not work on Microsoft Windows or MacOS platforms.


  • NodeJS 18.x
  • MongoDB 6.0.x

64-bit support only

32-bit MongoDB processes are limited to about 2 GB of data. The reason for this is that the MongoDB storage engine uses memory-mapped files for performance. For this reason, MongoDB decided not to support 32-bit, so we also dropped the 32-bit support for new installations, starting from version 16.02.


Countly requires at least 2 CPUs (the more the better) for a good user experience.


  • At least 2 GB of RAM for testing purposes (4 GB of RAM for Countly Enterprise)
  • 4 GB of RAM for moderate traffic
  • 16-64 GB of RAM or more for high traffic servers

Note that you may need different installation methods, such as sharding, in order to distribute traffic to several servers when receiving multi-billion API requests per month. Contact the Countly team to discuss how to deploy Countly in a sharded environment.

Countly will not work on Linux servers with less than 2 GB of RAM.


Disk requirements depend on the number of events and segmentations you send to your server.

  • At least 20 GB of disk space for testing purposes or low-traffic servers
  • At least 100 GB of disk space for moderate traffic
  • 1 TB or more for high traffic servers (SSD recommended)
