The publicly available instance of the tool hosted on is hosted on a private cloud located in Germany. Your data is secure and it is made sure that your privacy is respected and everything is GDPR compliant. The project is developed with very modern and broadly used tools which are the React framework for the client and Go as the driving programming language for our server code. All parts of the application are containerized and the best part is that you even get a Kubernetes deployment if you want to host your instance of the tool. started as a challenge for two friends in Nuremberg - who thought they could develop a better tool than many many competitors during the course of a single summer evening - has grown into a widely popular application.
