Editorial disclosure: I work at Zellbox, so this post is naturally biased. I’ve tried to describe Cliengo as accurately as possible based on their public product pages as of August 2026. If you find a factual error, message me on LinkedIn and I’ll fix it. No affiliate links.
If you’re comparing Cliengo with other WhatsApp platforms, you’ve likely also seen Landbot, Manychat, or ChatGuru. Cliengo is an Argentine lead-capture platform — website chatbots + WhatsApp bots + basic CRM fields for LATAM SMBs. Zellbox is a different product — appointment-driven small businesses that need WhatsApp reminders tied to a calendar.
Where Cliengo fits
Cliengo is at its best when your business needs a lead-capture funnel — website widget → chat qualification → CRM record → WhatsApp handoff. Real-estate agencies, car dealerships, marketing agencies working inbound-form-fill leads: Cliengo fits that.
Where Zellbox fits
If your business runs on visits, you’re not capturing leads — you’re managing appointments already booked. Zellbox syncs with Google Calendar, fires 24 h + 2 h reminders on the appointment schedule, and stores signed consent PDFs on the customer record.
Feature-by-feature
| Zellbox | Cliengo | |
|---|---|---|
| Google Calendar sync | Native, bidirectional | Not native |
| Appointment reminders | Native templates + schedule | Not the focus |
| Signed consent PDFs | Native | Not available |
| Website lead-capture chatbots | No | Native + strong |
| Pricing entry | Free forever, Pro $29/mo (5 users) | ~$25-40/mo |
When to pick which
Pick Cliengo if: your business runs on inbound-lead-capture funnels — website widget converting visitors to WhatsApp threads.
Pick Zellbox if: your funnel isn’t website-visitor → captured-lead — it’s already-booked-patient → confirmed-appointment. Zellbox works from your Google Calendar, not from a website widget converting strangers.
