Breaking news: We are working on the next major version of Kimai!

Go ahead and 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)

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)

Please visit us at GitHub to find out more.


  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!

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

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.

Our documentation has information about fetching the latest development version.


A couple of years ago we hosted Kimai at Sourceforge, you can find all old versions there. But thats ONLY for informational purpose, so we advise: DON’T! That why we don’t provide a link anymore … its completely outdated.
