Reviewer scorecard
“Cal.com offers the same features with open source. Calendly's API exists but the platform is locked down.”
“The open protocol for secure communication. Self-hosting and bridging to Slack/Discord/Telegram is powerful.”
“Cal.com is free and open source with equivalent features. Hard to justify Calendly's pricing anymore.”
“UX is still rough compared to Slack or Discord. The decentralization benefits don't outweigh the polish gap for most teams.”
“Brand recognition matters for client-facing scheduling. Calendly is still the name people trust.”
“Decentralized, end-to-end encrypted communication is the right architecture. Matrix is building the open alternative.”
