What is Intercom and how does it differ from Zendesk?

Intercom is a customer communications platform built around conversational support — chat, in-app messaging, and proactive outreach. Zendesk is a ticket-based support system better suited for high-volume support operations with complex workflows and reporting. Intercom is better for SaaS companies wanting to combine sales chat, onboarding, and support in one tool. Zendesk is better for teams with structured support processes, SLAs, and large support teams.
