Exciting news: We are working on the next major version Kimai 2 and invite you to read the announcement, visit the new website and participate at Github.



  • Release: Contains all the files that are required to install Kimai directly
  • Stable: is the developer version of a release, needs some post-install work (like composer install --no-dev)

Requirements for Kimai are only:
MySQL 4.3 and PHP 5.5 (required extensions: mysqli, iconv, php-xml)


  1. Use a modern Browser
  2. You need at least PHP 5.5 and access to a MySQL database.
  3. Start your browser and go to your Kimai directory.
  4. Kimai has a step-by-step installer, just follow the instructions.

IMPORTANT: Remove the installer directory when you’ve successfully installed Kimai.


Please see the Update documentation for more information on how to update to a newer version of Kimai.
