What is Kimai?
Kimai is open-source time-tracking software that runs on your own infrastructure. The project has existed for over a decade and targets teams, freelancers and small businesses that want to track and bill working hours by project. Because the application is self-hosted, all data stays under your own control. There is no cloud dependency, no usage fees, no external servers.
Core features
- Time tracking by project and client: Working hours can be assigned granularly to individual projects, clients and activities.
- Invoice generation: Tracked time can be converted directly into invoices, eliminating manual transfer work.
- Reporting and export: Evaluations across teams, time periods and projects are available and can be exported to common formats.
- User management: Multiple users work in the system simultaneously, with different roles and access rights.
- API access: A REST API allows integration with external tools and custom automations.
Who is Kimai for?
Freelancers billing client projects benefit most from the direct connection between time tracking and invoicing. Small agencies can manage teams and monitor workload through reports. The one requirement is a willingness to run your own server. Without experience with PHP applications, web servers or Docker, setup can stall at the first step. Ongoing updates and database maintenance add to that overhead.
Context & alternatives
Kimai sits in the self-hosted time-tracking segment, which is comparatively small. Most competitors, such as Toggl Track or Clockify, are SaaS products. Those who avoid that category because data should not sit on third-party servers have few comparable alternatives with a similar feature set. That is what makes Kimai relevant: when privacy requirements or compliance rules rule out a cloud solution, Kimai is the obvious first candidate.
