Reviewer scorecard
“Cal.com offers the same features with open source. Calendly's API exists but the platform is locked down.”
“Drop-in chat that actually looks good. Pre-built UI with customization saves weeks of development.”
“Cal.com is free and open source with equivalent features. Hard to justify Calendly's pricing anymore.”
“Building chat from scratch is a trap. TalkJS handles the hard parts — notifications, read receipts, moderation.”
“Brand recognition matters for client-facing scheduling. Calendly is still the name people trust.”
“Every app needs messaging. Pre-built chat infrastructure will become as standard as pre-built auth.”
