One of the two products FreeScout names itself against on its homepage. Help Scout bills per user every month plus a per-resolution AI charge; FreeScout bills per module once and never per user.
The other name in FreeScout's own positioning line. The capability set a Zendesk buyer shops for costs $70.97 once here, for an uncapped number of agents, against a recurring seat and per-resolution bill.
The other self-hostable option in this set, and the closer comparison on licensing: Chatwoot keeps a proprietary enterprise directory, while every one of FreeScout's 71 paid modules ships under AGPL-3.0.
Self-hosted and free with no module catalogue to buy, so features that cost money on FreeScout are either present or absent rather than purchasable. Zammad also sells a hosted edition, which FreeScout does not.
