Best open-source ITSM
The best self-hosted ITSM split in the c17.io catalog is GLPI for a GPL-3.0 asset and ITIL desk (the published ServiceNow/Freshservice/JSM stack), Zammad for AGPL-3.0 email tickets (already on /best/helpdesk), iTop when you want that AGPL-3.0 CMDB/ITSM box, and Chatwoot when the job is a shared inbox rather than ITSM. Jira Software stays on /replace/jira. A Freshdesk-shaped inbox stays on /replace/freshdesk.
