Calcom, formerly known as Calendso, is an open source Calendly alternative. With Calcom you are in charge of your own data, workflow and appearance. You have full control of your events and data, and have a power scheduling infrastructure. Calcom is an alternative to Alf.io. In this step by step guide I will show you how to Install Calcom on your Synology NAS using Docker and Portainer.
