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. It includes many of the features you see at the demo site, which are not yet available in a stable release.

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 installation program, just follow the instructions of the installer.

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. Additionally you need to make all ‘compile’ folders (also inside all extension subfolders!) writable for PHP. Writing permission must also be granted to the ‘temporary’ folder and the included ‘logfile.txt’.

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