About Smooch (Sunshine Conversations)

Smooch was an independent messaging API platform founded in 2015 that allowed developers to connect multiple chat channels — WhatsApp, Facebook Messenger, LINE, WeChat, Telegram, and others — into a single conversation thread. Zendesk acquired Smooch in 2019 and rebranded it as Sunshine Conversations, folding it into the Zendesk Suite as the underlying conversation orchestration layer. According to Zendesk's own documentation, Sunshine Conversations is now available exclusively as part of Zendesk Suite Professional ($115/agent/month) or higher — it cannot be purchased as a standalone product.

Converge is an independent customer support inbox at $49/month flat for up to 15 team members, with native connections to WhatsApp, Telegram, Discord, Instagram, Zalo, Messenger, Gmail, email, and an embeddable chat widget. Where Sunshine Conversations is an API middleware layer that requires Zendesk Suite as a prerequisite and developer resources to implement, Converge is a ready-to-use inbox product with a 14-day free trial, no credit card required, and no annual contract.
