1. CX Inbox

CX Inbox was built specifically for support teams that use WhatsApp as their primary channel. It is not an “omnichannel” platform that added WhatsApp later; it is WhatsApp-native from day one.

What is included

  • Shared inbox with automatic assignment by rules, teams and schedules
  • AI bot with visual flows — drag & drop editor, no code. The bot follows deterministic flows for transactional operations (check balances, generate payments, report issues) and uses generative AI for open-ended questions
  • RAG (knowledge base) — upload your documents and the bot answers with that information. No extra cost
  • Native CRM/ERP proxy — connect any external API and display customer data in the inbox sidebar, no code required
  • Bulk campaigns with Meta templates, CSV import and real-time metrics
  • AI-powered analytics — ask your dashboard questions in natural language
  • Agent tools — human agents can execute the same bot tools directly from the inbox
  • AI autocomplete — Gmail Smart Compose-style suggestions as the agent types

Pricing

  • Free: 1 agent, shared inbox, limited campaigns
  • Starter: $29/mo per agent, basic AI bot, unlimited campaigns
  • Professional: $79/mo up to 15 agents, full AI bot with RAG, AI analytics
  • Enterprise: custom pricing, unlimited agents, guaranteed SLA

Who is it for

Support teams that need a serious WhatsApp inbox with an AI bot that actually queries their systems. If your operation is 100% WhatsApp and you need the bot to do things (not just chat), CX Inbox is the most complete option for the price.

2. Wati

Wati is probably the most well-known Respond.io competitor. It has good traction (16,000+ customers) and a relatively simple interface.

The good

  • Easy-to-use interface, low learning curve
  • 92 pre-built chatbot templates
  • Native integrations with HubSpot, Salesforce, Zoho, Shopify
  • Well-documented API

The not so good

  • Charges ~20% markup on Meta WhatsApp fees. At high volume, the markup can exceed the subscription cost
  • The AI bot (KnowBot) is limited to 250 responses/month on the base plan
  • Each additional bot response has an extra cost
  • Limited support outside English

Pricing

  • From $49/mo (annual plan) with 3 agents
  • The message markup is the most important hidden cost

Verdict

Wati works well if your volume is low and you do not mind the markup. But if you send thousands of messages per month, that ~20% extra adds up fast.

3. Trengo

Trengo is a Dutch shared inbox platform that supports multiple channels (email, WhatsApp, Instagram, live chat). It is more “omnichannel” than “WhatsApp-first”.

The good

  • Real multichannel support (not just WhatsApp)
  • Modern, well-designed interface
  • Automations with rules and macros
  • Good presence in Europe and Latin America

The not so good

  • The base price is high ($99/mo) and the AI bot is an add-on with extra cost
  • No RAG or built-in knowledge base
  • WhatsApp setup can be complex
  • Advanced features are in higher-tier plans

Pricing

  • From $99/mo (Essentials plan, 5 users)
  • AI bot and advanced automations as add-ons

Verdict

Good option if you need to handle multiple channels besides WhatsApp. But if your primary channel is WhatsApp and you need an AI bot, the total cost can be high.

4. SleekFlow

SleekFlow is a Hong Kong-based platform focused on social commerce. It connects WhatsApp, Instagram, Facebook Messenger and other channels with sales features.

The good

  • Good e-commerce integrations (Shopify, WooCommerce)
  • Visual flow builder for automations
  • Product catalog within WhatsApp
  • Social CRM features

The not so good

  • The AI bot is an add-on, not included in base plans
  • Documentation and support are primarily in English and Chinese
  • Pricing can scale quickly with add-ons
  • Less focused on customer support workflows

Pricing

  • From $79/mo (Pro plan)
  • AI bot, advanced integrations as add-ons

Verdict

Ideal if your use case is social commerce (selling through WhatsApp). For pure customer support, there are more specialized and affordable options.

5. WhatChimp

WhatChimp is a smaller platform focused on WhatsApp marketing and bulk campaigns. It has accessible pricing and no message markup.

The good

  • Accessible pricing ($29/mo)
  • No markup on WhatsApp fees
  • Simple interface for bulk campaigns
  • Spanish language support

The not so good

  • The bot is basic (simple flows, no generative AI)
  • No RAG or knowledge base
  • Shared inbox features are limited compared to more mature platforms
  • Fewer integrations available

Pricing

  • From $29/mo
  • No hidden message charges

Verdict

Good option if your main need is sending bulk WhatsApp campaigns at a good price. For customer support with advanced AI bot, it falls short.

So, which one should you choose?

It depends on what you need:

  • WhatsApp customer support with a serious AI bot: CX Inbox. Deterministic flows + generative AI, RAG included, native CRM proxy, transparent pricing
  • Low volume with pre-built integrations: Wati. But watch out for the message markup
  • Multichannel (not just WhatsApp): Trengo. Good product, but expensive
  • Social commerce: SleekFlow. If you sell through WhatsApp, it has the tools
  • Affordable bulk campaigns: WhatChimp. Simple and accessible

FAQ
