Pricing
Tawk.to's free plan is real. That does not make it the same product.
Tawk.to is unusually strong on price: its core live chat, ticketing, hosted knowledge base, CRM, and chat pages are offered for $0 with unlimited agents and chats. If the job is manual live chat on a tight budget, Tawk.to is hard to beat.
HeyZinc is not trying to win a free-widget contest. Starter is $19/mo, Growth is $99/mo, and Enterprise is custom because the product includes voice-native workflows: direct website calls, AI receptionist behavior, outbound calling, visitor notifications, tracking links, adaptive knowledge, and deployment-control options.
