It combines live-chat and email conversations in one inbox, provides an embeddable website chat widget, and supports searchable multilingual help-center content.

The system also provides event-based automations, capacity- or criteria-based assignment, SLA tracking, custom roles and permissions, CSAT surveys, analytics, macros, custom attributes, SSO through Google, Microsoft, or OIDC, HTTP/JSON APIs, webhooks, activity logs, and conversation search. It can be deployed through Railway or Docker, with PostgreSQL and Redis provisioned or configured for the deployment.
