- License: AGPL-3.0
- Deployment: Docker / Kubernetes / DEB/RPM

1. The Executive Summary
What is it? Zammad is an enterprise-grade helpdesk and ticketing system designed to replace tools like Zendesk or Intercom. It consolidates all communication channels (Email, Twitter, Telegram, Chat, Phone) into a unified dashboard. Unlike many "Open Core" alternatives, Zammad commits to a "100% Open Source" model, meaning the self-hosted version has feature parity with their commercial SaaS offering.
The Strategic Verdict:
- 🔴 For Minimalist Teams: Caution. The stack (Rails + Postgres + Elasticsearch) is heavy for a simple "contact form" replacement.
- 🟢 For Customer-Centric Enterprises: Strong Buy. It offers the full power of an expensive enterprise helpdesk (SLAs, Knowledge Base, Reporting) with zero licensing costs and full data sovereignty.
2. The "Hidden" Costs (TCO Analysis)
| Cost Component | Proprietary (Zendesk) | Zammad (Self-Hosted) |
|---|---|---|
| Agent Pricing | $50-$200/agent/mo | $0 (Unlimited Agents) |
| SSO/SAML | Enterprise Tier Only | Included |
| Data Access | API Rate Limits | Direct SQL Access |
3. The "Day 2" Reality Check
🚀 Deployment & Operations
- Infrastructure: Requires a robust environment. Zammad depends on PostgreSQL for storage, Redis for caching, and Elasticsearch for its powerful search capabilities. It is not a single-binary deploy.
- Backups: Built-in backup scripts allow for full system snapshots, ensuring disaster recovery is straightforward.
🛡️ Security & Governance
- Identity: Native integration with LDAP and SAML allows it to slot seamlessly into existing corporate IAM infrastructure (Active Directory/Okta).
- Auditability: Every action on a ticket is logged, providing a complete audit trail for compliance and performance review.
4. Alternatives & Ecosystem
- Alternative: Zendesk (Proprietary) - The market leader, but expensive and data-locked.
- Alternative: Intercom (Proprietary) - Focuses more on "Chat/Engagement" than structured ticketing.
- Alternative: FreeScout (Open Source, PHP) - A lighter alternative (Help Scout clone) for teams that don't need the complexity of Zammad.
