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.
Grok Deepest multi-agent shared inbox with routing, SLAs and notes plus mature AI agents that resolve support queries using RAG and CRM context; transparent zero-markup Meta fee pass-through; high real-user satisfaction and robust WhatsApp-native handling within omnichannel; strongest fit for typical mid-market CS teams that need scalable agent workflows.
Where it falls shortper 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.
per Grok Contact-based pricing escalates at volume and full AI/automation requires Growth tier or higher, making it less ideal for pure low-volume WhatsApp-only micro-teams.

Grok Fastest guided onboarding and practical shared team inbox purpose-built for WhatsApp CS; effective no-code chatbots and automation that handle routine support FAQs at low entry cost; broad SMB adoption for everyday multi-agent support without heavy setup.
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 shortper 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.
per Grok Applies markup on Meta conversation fees and lags in AI depth plus advanced multi-agent/enterprise routing compared with stronger peers.

Claude Programmable WhatsApp via Conversations API plus Flex for a fully customizable contact center; unmatched flexibility, reliable global infrastructure, and official BSP status — you build exactly the support flow you want.
Grok Highest reliability, documentation quality and near-zero markup transparent pricing; enables custom high-performance CS flows or Twilio Flex contact-center builds that scale without lock-in; real value when engineering resources exist to own the stack.
Where it falls shortper Claude Build-it-yourself — needs real engineering to stand up an inbox; not turnkey and wrong for teams without developers.
per Grok No out-of-box shared inbox, AI or agent tooling—requires development, so unusable for non-technical support practitioners.

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 shortper 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.

Claude Enterprise omnichannel CPaaS with a strong Conversations agent app, deep WhatsApp support, global carrier reach, and reliable deliverability — well-suited to multinational support desks needing one platform across channels.

per Grok Opaque custom pricing and sales-gated complexity make it overkill and inaccessible for typical mid-market or SMB practitioners.

Rank history
Just missed the top 5
Claude 360dialog — excellent-value official BSP giving direct WhatsApp API access with no per-message markup, but it's raw API access — no agent inbox/support UI of its own, so you must bring or build the support layer
Gemini Twilio Flex — provides unmatched API flexibility but requires extensive engineering resources to build and maintain a functional support agent UI · Zendesk — treats WhatsApp as a secondary add-on channel within a traditional ticketing system, leading to high per-agent overhead for messaging-first support
Grok Gupshup — strong high-volume AI and emerging-market scale but shallower multi-agent CS inbox polish
