As answered by people managing Revolt.chat and BackReply.
BackReply's answer:
Someone would choose BackReply if their team works primarily in Slack but still uses Intercom for customer messaging. It lets teams reply, assign, route, and collaborate inside Slack while syncing everything back to Intercom automatically, which reduces workflow friction and keeps customer communication consistent and tracked.
BackReply's answer:
BackReply is designed to turn Slack into a reliable reply interface for Intercom, so teams can answer customers directly from Slack threads while Intercom stays the system of record. It focuses on removing context switching, preventing duplicate or lost replies, and enforcing routing and ownership so each conversation has a clear response path.
BackReply's answer:
The main audience is customer support and customer-facing teams using both Slack and Intercom, especially SaaS teams or cross-functional teams where engineers, founders, or product staff sometimes help with support conversations directly inside shared Slack channels.
BackReply's answer:
BackReply was built by a team with years of SaaS integration experience who had previously built products like Rasayel, Interhubz, and Octopods. The team states they created BackReply because they personally experienced the pain of managing support across Slack and Intercom and validated the solution through interviews and real support usage.

Really makes you wonder if/when Discord goes IPO, that Meta would buy a controlling stake in it? Fortunately there are open source alternatives even if they aren't as popular as Discord at the moment, such as Revolt Chat:... - Source: Hacker News / over 1 year ago
