CenasWe use Kimai at allroundDigital and are delighted with it. It’s really reliable, works without a lot of explanation and does everything I’d want it to do without being overloaded. Wonderful tool – would definitely recommend.
Niklas Schrötler
allroundDigitalWe have been using Kimai for time tracking at Pulse of Europe for quite some time now and are extremely satisfied with the experience.
As a non-profit, pro-European citizens’ movement, we coordinate a wide range of projects, campaigns and activities involving both staff members and volunteers. Having a reliable and transparent time-tracking solution is therefore essential for our daily work.
What particularly impresses us about Kimai is its simple and intuitive user experience. Working hours can be recorded quickly and easily, while projects and tasks can be clearly categorised and flexibly filtered. This allows us to maintain an overview even across multiple teams, projects and responsibilities.
Kimai helps us make our internal processes more transparent and efficient – both in our day-to-day operations and when evaluating project-related working hours.
For organisations and teams looking for a powerful yet user-friendly time-tracking solution, we can wholeheartedly recommend Kimai.
Hendrik Michel, PoE
Pulse of Europe e.V.We have been using Kimai for two years now to track the time spent on each phase of our projects and to bill our clients for the hours worked. The software is comprehensive, intuitive, and fully meets our needs. In addition to this, Kevin has always been helpful and attentive to our needs!
Alessandro Pollastri
Comunità Papa Giovanni XXIIIWe recently made the switch from Toggl to a self-hosted Kimai. As a TYPO3 agency, open source, data sovereignty, and full control over the software were essential to us. We wanted to decide ourselves when to enable specific features and have the freedom to implement our own customizations. The migration of data from Toggl to Kimai was smooth, and our team quickly adapted to the interface, which resembles Toggl but offers more advanced options—especially for reporting and analytics.

Pagemachine AGWe have been using Kimai in our electrical company for the past two years, and we are currently transitioning to a fully paperless process with Kimai only for managing timesheets. Our employees adapted quickly, as we developed a customized workflow tailored to our business needs. Thanks to Kimai, we’ve reduced the time spent processing timesheets for our 20 employees, as well as managing project reports (construction reports, work reports, daily customer reports), from around 10 hours per week to just 2 hours. We also underwent a payroll tax audit without any issues; the only requirement is the employee’s signature on the timesheet. The developer of Kimai is also very receptive to useful feature suggestions, which makes me confident that even more great improvements are on the way.

EtronetKimai has worked perfectly for CodeWeavers. We spent a great deal of energy comparing timesheet solutions, from proprietary to open source. None of the proprietary solutions had the functionality and simplicity of Kimai. Because it’s open source, we can confidently rely on it for years and years to come. Finally, we have hired Kevin to help us customize Kimai for our needs. His work has been fantastic. As a result, we have a professional solution, custom tailored to our needs, for far less than we were prepared to spend on one of the proprietary solutions.
