Picking between them
Chatwoot
Built around its core job, Chatwoot stays out of your way. It runs comfortably on 2 vCPU / 4 GB here. Its install count is not luck — it is the default answer for most support & crm questions we see.
Zammad
The core loop is what Zammad does best. It runs comfortably on 2 vCPU / 4 GB here. Close second, and some teams prefer its take on the problem.
FreeScout
FreeScout covers the essentials without demanding a manual. It runs comfortably on 1 vCPU / 2 GB here. Lesser known, often a better fit for smaller teams.
Tiledesk
Tiledesk covers the essentials without demanding a manual. Spec: 2 vCPU, 4 GB RAM, 50 GB disk. A niche pick that earns its place.
Choosing a server
None of these need a big machine. Budget roughly €0.046/hour for the largest spec in the table (peak 2 vCPU, 4 GB), and less for the rest. Pick an app above to see its exact sizing.
