GLPI if you want assets and an ITIL desk (the published ServiceNow path). Zammad if the job is email tickets — /compare/zammad-vs-glpi.

Jira Software is /replace/jira (It's a Plan / Plane). This page is Jira Service Management — tickets and a portal.

Chatwoot is the shared inbox — /replace/freshdesk. This page is ITSM.

GLPI / Zammad

ITSM and tickets you host. GLPI is GPL-3.0; Zammad is AGPL-3.0 — ServiceNow, Freshservice, and Jira Service Management without the ITSM seat.

The problem

ServiceNow is an ITSM operating system. Freshservice is the Freshworks desk. Jira Service Management is Atlassian's ITSM seat — not Jira Software (that lander stays on /replace/jira). You wanted assets, tickets, and a portal. GLPI is GPL-3.0 (glpi-project/glpi): assets, ITIL desk, licenses. Zammad is AGPL-3.0 tickets (already on /best/helpdesk). iTop is a CMDB/ITSM box if that is the shape. This is not ServiceNow's every workflow SKU, Freshservice's MSM, or JSM's every ITSM add-on. A shared inbox stays on /replace/freshdesk (Chatwoot).
