Comparisons that start from osTicket, the GPL2 PHP support ticket system with free, cloud and virtual appliance editions.
Two lightweight PHP helpdesks compared for small support teams: osTicket's form and email ticketing with core plugins against FreeScout's shared-inbox model and paid modules, plus requirements, upgrade paths and authentication options.
Hosted osTicket against running the free open-source download yourself: published per-agent cloud pricing, the virtual appliance option, community-only support for self-hosted installs, and the upgrade and backup work you keep when self-hosting.
