Issues
Let's face it: Calendly and other scheduling tools are awesome. It made our lives massively easier. We're using it for business meetings, seminars, yoga classes and even calls with our families. However, most tools are very limited in terms of control and customisations. That's where Calendso comes in. Self-hosted or hosted by us. White-label by design. API-driven and ready to be deployed on your own domain. Full control of your events and data. Calendso is to Calendly what GitLab is to GitHub.
