Open Source
We love open-source software - Kimai is open-source and will ever be, that is a promise!
No vendor lock-in
Vendor lock-in can cost a lot, not just in cash but also in hours. With Kimai, you can host it yourself, have us host it for you, or fork it and change it. You're never locked into a hosted product, and all of your data is easy to export so that if you ever decide Kimai isn't for you anymore, your data is still yours (the same applies to the paid plans, we offer data export upon cancelation).
Learn more about the open source version at www.kimai.org.
Always transparent
With closed source software, you have only the vendor's claims that they're keeping the software secure and adhering to standards. The visibility of the code behind open source software means you can see for yourself. You can always see our responses to the community, the release schedule and milestones, and every commit and pull request review.
Learn more about the code behind Kimai at our GitHub repository.
