What you give up either way

Hosted SLA, uptime and sub-second response infrastructure
Pre-built marketplace integrations (many CRMs/helpdesks listed)
Managed GDPR/compliance attestations and enterprise security processes
Turnkey WhatsApp Agent and vendor-managed phone/WhatsApp integrations
Polished analytics and conversion-tracking dashboards out of the box

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Chat whisperer, and it does not prove anyone has run it for a month. How we decide.
