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.

We 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.

Kimai has been a fantastic discovery. I reviewed several other time trackers, and frankly, none of them compared. Kimai just felt better right away. It’s easy to set up and use, with a clean design and just the right balance between features and simplicity, and the self-hosting option is a huge plus.

Highly recommended and big thumbs up from me!

As a non-profit organization, when it comes to digital tools, we care not only about costs but also about transparency, data privacy, and long-term independence. Kimai won us over with its open-source approach, the fair non-profit pricing, and the fast, personal support.

When I started to identify a time reporting software for our medium size enterprise (~30 people distributed all over United States and Canada) in the software service industry for onsite and remote services, I had several programs in my mind. In my specification I had the following things to be covered

  • Customer related time reporting
  • Project related time reporting
  • Time approval
  • Various hierarchies in user and access levels
  • Open data interface for potential interfaces to other software packages (such as various payroll software packages for Canada and US, ERP for invoicing)
  • Time budget for hourly packages
  • Time reporting to customers with time budget
  • The data is mine and I always want to have access to it
  • I would like to create plugins if I need to add features that do not yet exist

I continued my search but always came back to Kevin Papst’s time reporting software Kimai. So I installed it on a shared host. I continued to set up a few users and imported a few customers, projects and finally understood how activities are to be set up (global and local). This is a feature that surprised me even more. Well implemented! I finally rolled it out to a small group and then the entire team. The time reporting is now fully implemented within 2 months from first idea to fully operational.

Then the demands grow with the possibilities: I purchased a few plugins and these were installed as simple as the main software. Then, when I had even more requests that I didn’t find an answer by plugins, I reached out to the developer Kevin asking for help with changing a report and he simply answered to consider this for the entire software, not just a module for me. It may be within some of the next releases.

In summary, Kimai is a flexible time reporting package with active code, modern, responsive and fast user interface and a fast responding support.

Thanks, Kevin, for this nice software package!

We have been using Kimai for our time management for a short time and are very satisfied. A nice design and easy operation were important to us, but the biggest plus point is the support: The team responds quickly and addresses all wishes and concerns, even if a special solution is needed. Therefore, we absolutely recommend it to anyone looking for a time tracking solution 👍

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.

I have been using Kimai for several years. First in a company as part of a project team. Later, when I started my own business on the side, I was looking for a simple time tracking tool and returned to Kimai. First self-installed, then in the cloud. For 3 euros in operating expenses per month, as a small part-time entrepreneur, I get exactly what I need: fast tracking, an overview of outstanding items, and lightning-fast billing with a clean timesheet. But even for huge projects with a large number of people, it remains clear, comprehensible, and easy for everyone to use. And the support, in the person of Kevin, responds quickly and comprehensively to everything you need. Many thanks for that!
