Zendesk is the enterprise standard for customer support with ticketing, live chat, knowledge base, and AI-powered automations. Reliable but increasingly expensive and complex.
Reviewer scorecard
“Open source and self-hostable scheduling with a great API. Webhooks and workflows enable custom booking flows.”
“Robust API and marketplace. Building custom apps and integrations is well-supported. Webhooks and triggers are powerful.”
“Why pay Calendly when Cal.com is open source? The feature set matches or exceeds Calendly for most use cases.”
“Bloated, expensive, and the UI hasn't meaningfully improved in years. Intercom and Freshdesk offer better value.”
“Scheduling infrastructure should be open. Cal.com is the open-source standard.”
“The help center themes are limited and customization requires coding. Not the most design-friendly support platform.”
