   Claude #1Gemini #1

   Purpose-built messaging-first support platform with the deepest native WhatsApp handling of any inbox — multi-agent shared inbox, visual workflow automation, routing, and AI agents tuned for conversational channels rather than bolted onto a web-chat product; strong value for the mid-market WhatsApp-first team the category actually serves. Near-tie with Zendesk at #2 — Respond.io leads only because the question is WhatsApp-specifically.

   Claude Purpose-built messaging-first support platform with the deepest native WhatsApp handling of any inbox — multi-agent shared inbox, visual workflow automation, routing, and AI agents tuned for conversational channels rather than bolted onto a web-chat product; strong value for the mid-market WhatsApp-first team the category actually serves. Near-tie with Zendesk at #2 — Respond.io leads only because the question is WhatsApp-specifically.

   Gemini Purpose-built for messaging-first customer support with direct Meta WhatsApp Cloud API integration (no extra markup per message), advanced visual workflow automation for multi-agent ticket routing, and robust conversation lifecycle controls. Assumes support operations prioritize sophisticated routing and high-volume messaging workflows.

   Where it falls short

   per Claude Lighter on formal ticketing, SLA management, and enterprise reporting depth — not the right core for a large org that needs a full ITIL-grade helpdesk.

   per Gemini Escalating pricing tiers based on monthly active contacts and a complex feature set that presents a steep learning curve for non-technical teams.

   Gemini Dedicated WhatsApp support platform offering effortless setup, intuitive shared inbox management, and accessible no-code bot automation at a competitive price point for SMBs. Assumes support operations are concentrated entirely on WhatsApp; near-tied with Trengo for ease of single-channel deployment versus multi-channel scope.

   Claude WhatsApp-native shared team inbox built entirely on the Business API, fast no-code setup, affordable tiers, broadcast plus chatbot automation — the pragmatic default for small support teams that live in WhatsApp.

   Where it falls short

   per Claude Feature depth and multichannel breadth are limited; scales poorly for large or complex enterprise support operations.

   per Gemini Completely lacks support for non-WhatsApp channels (like email or live web chat), forcing multi-channel support teams to manage separate tools.

   Best-in-class support suite — ticketing, macros, SLA/routing, analytics, and a mature agent workspace — with WhatsApp integrated natively as a first-class channel via Sunshine Conversations; the safe pick for an established support org where WhatsApp is one channel among many.

   Where it falls short

   per Claude Expensive and heavy; WhatsApp is a bolt-on channel, not the center of gravity, so it's overkill and awkward for a WhatsApp-first SMB.

   Where it falls short

   per Claude Build-it-yourself — needs real engineering to stand up an inbox; not turnkey and wrong for teams without developers.
