Workflow coverage and comparison notes
Handle customer support tickets, email integration and multi-agent service desk operations using open-source Zammad instead of Kustomer.
Before you switch
Resource-intensive backend (requires Elasticsearch/OpenSearch, PostgreSQL, and Redis); steeper administrative learning curve.
