Comparison Overview
Why teams consider OnSync after WATI
WATI is a popular starting point for WhatsApp broadcasts and order updates. But as programs expand, teams need more than templates and flows—they want AI copilots with grounded knowledge, shared inboxes for every channel, campaign analytics, and compliance guardrails. OnSync brings those pieces together without relying on third-party scripts.
When to upgrade
- You need AI to handle multilingual FAQs, not just quick replies.
- You manage multiple channels and want one inbox with SLA enforcement.
- You require CRM sync, audit logs, or data residency for enterprise customers.
Where WATI fits
- Catalog broadcasts and simple drip sequences.
- Teams that only operate inside WhatsApp and don’t need cross-channel collaboration.
- Early-stage businesses with minimal compliance requirements.
Side-by-side comparison
| Capability | OnSync | WATI |
|---|---|---|
| Team Inbox & collaboration | Unified inbox with assignments, hidden notes, SLA timers, and channel history for WhatsApp, Instagram, Facebook, and Telegram. | Shared inbox for WhatsApp; cross-channel collaboration and SLA alerts require manual workarounds. |
| AI agent & knowledge | Native AI Agent with knowledge grounding, guardrails, and bilingual tone controls. Smart Triggers keep SLAs intact. | Flow-based chatbot; needs external LLMs to match knowledge-grounded AI and guardrails. |
| Messaging campaigns | Built-in WhatsApp marketing, re-engagement, and template governance with quiet-hour rules. | Strong catalog broadcasts but limited analytics and template management for multiple locales. |
| Contacts & integrations | Unified profiles with tags, attributes, revenue tracking, plus native HubSpot, Salesforce, Shopify, and payment webhooks. | Integrations focus on ecommerce; CRM sync often relies on third-party middleware. |
| Compliance & analytics | SOC 2, audit logs, custom permissions, bilingual analytics, and optional GCC data residency. | Basic analytics dashboard; advanced compliance features require enterprise contracts. |
Feature deep dive
Team Inbox & collaboration
OnSync offers a Team Inbox that spans WhatsApp, Instagram, Facebook Messenger, Telegram, email, and SMS. Assign owners, leave hidden notes, and keep SLA timers visible. WATI’s inbox centers on WhatsApp and requires external processes to mirror multi-channel context or enforce SLAs.
AI Agent & Smart Triggers
OnSync’s AI Agent answers FAQs, qualifies leads, and escalates complex threads with guardrails, while Smart Triggers auto-acknowledge DMs and notify owners before SLAs slip. WATI focuses on flow-based bots; deeper knowledge grounding and sentiment routing rely on third-party AI tools.
Messaging campaigns
OnSync governs WhatsApp templates, quiet hours, and response analytics in one dashboard. You can trigger campaigns from Shopify, payment events, or CRM actions. WATI manages catalog broadcasts but complex governance or A/B testing typically requires spreadsheets or agencies.
Contacts, analytics, and compliance
OnSync keeps unified contact profiles with tags, attributes, revenue data, and bilingual analytics. Compliance features include SOC 2, audit logs, role-based access, and regional data options. WATI provides baseline dashboards, but advanced compliance usually requires enterprise upgrades.
