Zapext vs Whato CRM: an honest comparison of WhatsApp Web extensions

Whato CRM and Zapext compete in exactly the same space: extensions that turn WhatsApp Web into a sales tool, with a Kanban CRM, bulk messaging, and automation. That makes the practical details matter more than in comparisons against official-API platforms: where the extension is published, what it really costs, and how the chatbot decides what to say.

Who Whato CRM is

Whato is a WhatsApp Web CRM with a Kanban board, bulk messages, chatbot, multi-agent support, and webhooks. The differentiator it pushes hardest is AI: according to its official site (Jul/2026), the tool uses ChatGPT to optimize copy and speed up replies. The site also claims more than 10,000 entrepreneurs and offers a 3-day free trial with no card. It is an active competitor in content too, running a blog full of comparisons and extension roundups.

The detail that changes everything: the Chrome Web Store

As of Jul/2026, Whato's own site states the extension is "temporarily unavailable on the Chrome Web Store" and offers manual installation as the alternative. That matters for three practical reasons: an off-store extension skips Google's ongoing review; Chrome does not auto-update manually installed extensions; and manual installs are more error-prone for non-technical users. Zapext remains published and audited on the Chrome Web Store, with a 5.0 rating and 43 reviews (verified Jul/2026) — one-click install and automatic updates. If you are choosing a WhatsApp extension, this is a core criterion: the official store is the security layer between the extension's code and your WhatsApp account.

Pricing: what each one really costs

Whato's plans page lists "$15/month" or "$139/year" for up to 4 devices on the same number (Jul/2026) — without stating on the page whether the amount is in Brazilian reais or US dollars, and with no price on the homepage at all. If it is dollars, the cost in reais floats with the exchange rate. Zapext publishes its prices in reais: R$39/mo on Starter and R$79/mo on Plus (R$297 and R$549 yearly), with up to 4 users included on Plus, no per-message cost, and a 7-day money-back guarantee. Both models cover a small team on one number — the difference is how clearly you know what you will pay each month.

Chatbot: AI (ChatGPT) vs rules

Here Whato has a real differentiator. The embedded ChatGPT produces more natural replies and helps draft messages — a time-saver when you handle open-ended, varied questions. The flip side: generative AI can answer unpredictably, and in sales conversations an invented answer is expensive. Zapext's chatbot is rule-based (keywords and flows), with no AI: less "clever," but 100% predictable — it only says what you configured. For qualification funnels, option menus, and triage before a human takes over, rules work better than they sound.

When Whato is the right choice

• You want AI (ChatGPT) built into replies and message drafting.
• You don't mind installing and updating the extension manually while it is off the Chrome Web Store.
• You prefer a 3-day free trial with no card before deciding.

When Zapext is the right choice

• You want to install from the Chrome Web Store, with store auditing and automatic updates — as 3,000+ businesses already do.
• You prefer a clear price in reais — R$39 or R$79/mo — with no exchange-rate surprises.
• You want a predictable rule-based chatbot that never invents an answer to a customer.
• You need 4 users with round-robin and chat transfer on the same number.
• You value encrypted local data and a backup on your own computer.

Worth repeating what both share: they are WhatsApp Web extensions — neither uses the official API nor issues the green tick. If you are still mapping the category, see our guide to the best WhatsApp CRM and the comparison hub.
