We keep an eye on server compatibility, requirements for Kimai are only:
MySQL 4.3 and PHP 5.5 (required extensions: mysqli, iconv, php-xml)

DEV - Development version

A development version is the latest package we are currently working on. It might have new features, but it might be broken as well!

If you are an experienced user of Kimai and have the resources to help us with testing or just like to play with brand new features, you can download the latest development version.

Please help us, test it and give us your feedback if you find any problems.


  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.


When you update an existing installation, just replace the entire Kimai folder on your server. Writing permission must be granted to the ‘temporary’ folder.

When Kimai doesn’t start, the reason is probably wrong writing permissions on the mentioned files and folders!
