Kimai is a free, open source and online time-tracking software designed for small businesses and freelancers. It is built with modern technologies such as Symfony, Bootstrap, RESTful API, Doctrine, AdminLTE, Webpack, ES6 and many more. In this step by step guide I will show you how to install Kimai on your Synology NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest Kimai v2.15.0 release.
