Wapzen vs WATI.
Which one fits your business?

WATI and Wapzen both put automation on WhatsApp, but they start from different places. WATI is a platform built on Meta’s official WhatsApp Business API, designed for teams that broadcast, sell, and support customers at volume. Wapzen is built around AI agents: a chatbot that replies to incoming messages and a voice agent that answers and makes WhatsApp calls, running on the number you already use.

WATI

WATI has three plans. Growth is $39 a month and Pro is $79 a month, both billed annually; Business is priced on request. WATI says annual billing saves up to about 25% compared with monthly. Growth includes 3 users with no option to add more; Pro includes 5, and extra users cost $24 each per month ($59 on Business).

The plan is only part of the bill. WhatsApp charges per message for marketing, utility, and authentication templates, at rates that depend on the recipient’s country, and WATI bills these from its own rate card. AI is metered too: Growth includes 250 AI Co-pilot credits a month and Pro 500, extra credits start at $20 a month, and Astra AI agents are priced separately.

A five-person team on Pro pays $948 a year for the plan alone, before message charges and AI add-ons.

Wapzen

Wapzen is currently free, with every feature included: the AI chatbot, the AI voice agent, outbound calling campaigns, knowledge bases, and API tools. The AI models (OpenAI GPT and Anthropic Claude) and the voices are included, so you don’t need your own API keys. Because your number is linked by QR code rather than the Business API, there are no per-message fees, and calls have no per-minute charge. See the pricing page for details.

WATI’s prices are from its pricing page on the date at the top of this post. If Wapzen introduces paid plans, they’ll be listed on its pricing page.

WATI’s chatbot builder is flow-based: you design paths with keywords, buttons, and forms, with advanced chatbots on Pro. AI comes on top of that. AI Co-pilot helps your human agents write replies, and Astra lets you describe an AI agent in plain language and deploy it on WhatsApp once Astra is connected to your WATI account.

In Wapzen, the chatbot is an AI agent. You write its instructions, choose a GPT or Claude model, and attach knowledge bases built from text, PDF, or Word files. It answers free-text questions in the customer’s own words and language, and API tools let it look up an order or request a booking in your own systems. When you want to step in, you reply from the dashboard and take the conversation over.

Which is better depends on the conversation. For strict, menu-driven journeys (“reply 1 for sales, 2 for support”), a flow builder like WATI’s gives you exact control. For open questions about prices, opening hours, delivery, or your services, an AI agent trained on your documents handles far more without you mapping every path. Wapzen’s free WhatsApp chatbot guide shows the setup.

Both products handle WhatsApp voice calls, in different ways.

WATI lists WhatsApp Business Calling in its team inbox, so your team can take customers’ WhatsApp calls, and its Astra platform can run voice AI agents that answer and start WhatsApp calls, with settings for voice, call length, and silence handling. WATI notes that AI features roll out in phases, so confirm they’re enabled for your plan.

Wapzen was built around calling from the start. A voice agent answers incoming WhatsApp calls on your linked number around the clock and can call people back. You can also run outbound calling campaigns: add leads to a campaign and each one gets a call from your agent, with transcripts and campaign analytics in the dashboard. Voice agents can speak dozens of languages. Wapzen’s calls are WhatsApp calls only; it doesn’t dial regular phone numbers. More in the AI calling agent guide.

With WATI, you connect a number to the WhatsApp Business API, which WATI sets up without a setup fee. That means a Meta business account, a display name that Meta reviews, and approved templates for any message you start or send more than 24 hours after the customer’s last message. Then you build your flows and invite your team.

With Wapzen, setup takes four steps:

1. Sign up for free, without a card.
2. Create an agent: a chat agent, a voice agent, or both, with your instructions and knowledge base.
3. Scan the QR code with WhatsApp on your phone, the same way you link WhatsApp Web.
4. Go live: the agent starts replying to messages and answering calls.

The trade-off is the one in the table: the Business API is Meta’s official route and suits high-volume messaging, while a QR-linked number gets you going in minutes, with no approval or fees, on a product that isn’t an official Meta platform.

The short version: WATI is a messaging platform with AI added; Wapzen is an AI agent for WhatsApp chats and calls. If broadcasts and a human team inbox are the core of your WhatsApp strategy, WATI is worth its price. If you want customers who message or call you to get an instant, useful answer, Wapzen does that for free.

Wapzen links your number like WhatsApp Web, so it’s meant for answering people who contact you and calling leads who expect your call. Mass unsolicited messaging breaks WhatsApp’s terms on any account; use an official API platform for large opt-in broadcasts.
