Kimai

Kimai is an open-source, self-hosted web application that provides professional time tracking for freelancers and companies. It allows users to log billable hours, manage projects, and generate detailed reports to monitor productivity and costs across various clients. The application is designed to handle a wide range of scales, from individual freelancers to organizations with hundreds of active users.

The software is deployed as a web application on a server. It requires a PHP environment and a MariaDB or MySQL database. Installation options include Docker Compose for environments like Hetzner and DigitalOcean, manual SSH setup using Git and Composer, or hosting on Synology NAS devices. For users who do not wish to manage their own infrastructure, a hosted cloud version is available.
