Spiceworks Help Desk

Spiceworks Help Desk is a completely free, ad-supported ticketing system designed primarily for IT support teams. It includes cloud and on-premise versions, integrates with network inventory tools, and offers email ticketing, a user portal, and basic reporting. Its large community provides peer support. It is ideal for small IT departments, schools, and non-profits with zero software budget.

It scores decently for delivering essential ticketing and IT asset tracking at no cost, though the interface includes ads. Its strength is enabling professional ticket management for teams that otherwise might use only a shared email inbox.
