Reviewer scorecard
“Cal.com offers the same features with open source. Calendly's API exists but the platform is locked down.”
“The most complete chat API with pre-built React, Flutter, and native components. Moderation and threads are production-ready.”
“Cal.com is free and open source with equivalent features. Hard to justify Calendly's pricing anymore.”
“Expensive but building chat infrastructure from scratch is more expensive. Stream handles the edge cases.”
“Brand recognition matters for client-facing scheduling. Calendly is still the name people trust.”
“In-app communication is essential for engagement. Stream's infrastructure removes the need to build this yourself.”
