Reviewers see Zendesk as dependable, familiar support software that is easy to set up, useful for ticketing, help centers, and team workflows, and solid enough to become a default choice for many companies. But the sharper theme is frustration: users call the UX dated, say core tasks like search, macros, analytics, and custom reporting can be clumsy, and describe the product as slow to improve. Some also mention siloed systems, weak native CRM integration, slow support responses, and too much complexity for smaller startups.
