Self-hosted or hosted by us. White-label by design. API-driven and ready to be deployed on your own domain. You are in control of your events and data.
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.
100% in Control

“Calendso gives you greater control and was designed to be as versatile as possible — design and modify it your way. Once you start using it, you start wondering how you previously coped without it.”
