Versions

Some people struggle to understand the versioning of Kimai. That usually happens, when the app number and version number are mixed.

There are two distinct Kimai versions with totally different code bases. So the app name might sometimes contain the number 1 or 2. This usually relates to the “original” Kimai, which we call Kimai 1 sometimes (see the last image on this page).

The modern Kimai is sometimes called Kimai 2, but only if we need to differentiate between the original and the current Kimai. We use it on this page to explain this concept, but whenever we say Kimai we mean Kimai 2.

The following list is ordered from youngest to oldest version.

Kimai 2

This Kimai version was originally released in 2018 and is still actively developed today.

Released versions were 0.2 up to 2.26.0. That means there are multiple major versions existing, which combined from the app name part 2 and the actual release number like 1.30 or 2.0.22 leads to:

• Kimai 2 - v1.30
• Kimai 2 - v2.0.22
• Kimai 1.30
• Kimai 2.0.22
