“Open source and self-hostable scheduling with a great API. Webhooks and workflows enable custom booking flows.”
“Best platform for developer communities. Bots API is powerful. The fact that it's free for communities is unbeatable.”
“Why pay Calendly when Cal.com is open source? The feature set matches or exceeds Calendly for most use cases.”
“Search is still mediocre and discoverability is poor, but for community building there's nothing better at this price point.”
“Scheduling infrastructure should be open. Cal.com is the open-source standard.”
“Discord is becoming the default social layer for internet-native communities. Their Activities platform hints at bigger ambitions.”
