What users say about Kimai

At Kimai, we've designed our time tracking platform to meet the needs of agencies, teams, and freelancers. Our intuitive interface and powerful features help companies like yours work smarter and more profitably. You can now “listen” to the reviews of the real users.

Kimai really convinced me. I spent a long time looking for the right solution for us. The specifications were a low-cost solution for many employees where I didn’t have to buy a 30 EUR / month licence for a part-time employee. However, Kimai (which runs on our server) has all (and more) of the functions we need. Above all, start/stop via browser and app, assignment of projects and much more are optimal functions. It is the time recording system that I would recommend to agency friends.

I have been using Kimai cloud for more than 1 year, and I am very satisfied about it ! It became easier for me to send monthly reports to my clients and to track my time spent on the projects I’m working on. Thank you very much !

I’ve always preferred self-hosting services, but when I discovered Kimai, I saw the value in their free cloud plan. Wanting to support the developers (being a developer myself), I upgraded to the paid version, and it’s been worth every penny.

Recently, I made a mistake that almost wiped out all my data. Despite my plan not officially including support, Kimai’s team was there for me. They responded quickly and had my issue resolved within half an hour, saving me from a potential disaster.

As a freelancer, Kimai has become an essential tool for managing clients, projects, and tasks. It lets me track time accurately and create professional invoices effortlessly. For anyone looking to stay organized and efficient, I highly recomm

We’ve been using the brilliant Kimai tool for a while now and have recommended it to many people. Recently, we came up with an idea internally that we’ve implemented and are currently expanding. It involves an order management system with a management portal built on the Kimai platform. By the way, it’s absolutely fantastic. It’s truly impressive how well the tool has been documented and how open it is to customizations.

We 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.
