zammad Zammad is a web based open source helpdesk/customer support system. | 5.5k | — | 51 |
Zammad is a web-based helpdesk and ticketing system. Email, chat, social media, and phone calls all land in one unified inbox. Agents can see conversation history, leave internal notes, and escalate tickets through SLA-aware workflows. GPL-licensed, free to self-host. Rails app with Elasticsearch for full-text search. Docker-based deployment is the recommended path. You need Elasticsearch running alongside it, which adds to the resource footprint. Plan for a dedicated server with 4GB+ RAM for any real usage. Active development with regular releases. Support teams canceling Zendesk or Freshdesk can land most of the core workflows here. The interface is not quite as polished but it is genuinely functional. Covers ticket queues, SLAs, customer history, and basic automation rules. The catch: no native live chat widget. You can integrate third-party chat but it is not seamless. And the mobile app is an afterthought compared to Zendesk's.
