Cal.com is a well-regarded, open-source scheduling platform that developers can self-host and customise deeply. Book with Schedulo takes the opposite trade-off: a fully-hosted, ready-to-use product you can set up in minutes — with WhatsApp, UPI payments, and QR booking included, and nothing to deploy or maintain.
