Zammad vs FreeScout (2026)
Zammad and FreeScout are both open-source, self-hostable help desks, but Zammad leans enterprise with LDAP/SSO and a cloud tier while FreeScout is a lean, free shared inbox. Compare auth, channels, and cost.
Zammad
Open-source web-based help desk and ticketing system with a generous free self-hosted tier. Merges support channels into one queue with strong LDAP, SSO, and API support for technical teams.
FreeScout
Free, open-source help desk and shared inbox you self-host — a Zendesk or Help Scout alternative with no per-agent fees and full data ownership.
TL;DR
- Pick Zammad if you need enterprise auth (LDAP/AD/SAML/SSO), multi-channel ticketing including social and phone, and the option of a managed cloud tier instead of self-hosting.
- Pick FreeScout if you want the lightest free self-hosted shared inbox, unlimited agents at zero per-seat cost, and a module-based model where you only pay for extras you actually use.
Pricing
Both are free to self-host. Zammad is AGPLv3 with no license cost on the self-hosted edition, plus a managed cloud from €5/agent/mo and a Plus tier at €24/agent/mo that covers features Zendesk locks behind $55+ plans. FreeScout's core is free with unlimited agents and mailboxes; premium modules (CRM, live chat, KB, WhatsApp) add cost, and a heavily-moduled setup can approach a low-tier commercial plan. If you want a budget managed option, Zammad's cloud is the more credible turnkey path; for pure free self-hosting, both work, with FreeScout being lighter to run.
Authentication and enterprise fit
Zammad's standout advantage is enterprise authentication: LDAP, Active Directory, SAML, OAuth, and SSO all supported out of the box, plus a full REST API. That makes it a natural fit for IT and support teams in larger or compliance-bound organizations — particularly in Europe and where data sovereignty matters. FreeScout's authentication is lighter and aimed at smaller teams; it can extend via modules but doesn't match Zammad's built-in enterprise auth story.
Channels
Zammad consolidates email, phone, live chat, Twitter/X, Facebook, and web forms into a single ticketing queue out of the box — broader native channel coverage. FreeScout's core is email and shared-inbox focused, with live chat, WhatsApp, Slack, and Telegram available as modules. If you want multi-channel including social and phone without assembling add-ons, Zammad is more complete; if email is your backbone and you'll add channels selectively, FreeScout's modular approach keeps things lean.
Infrastructure and maintenance
FreeScout is a PHP/Laravel app that runs comfortably on inexpensive shared hosting — low operational overhead and a familiar stack for most web admins. Zammad's self-hosted deployment is heavier (a Ruby-based stack with more moving parts), carrying real server, patching, and admin overhead. Both put upgrades and security on you for self-hosted editions, but FreeScout is the easier and cheaper to keep running on modest infrastructure.
Usability
Zammad's UI is functional but less polished than commercial SaaS and can feel less intuitive for non-technical agents. FreeScout's email-style shared inbox is deliberately familiar and friendly. For agent adoption among non-technical staff, FreeScout has the edge; for technical IT teams, Zammad's interface is perfectly serviceable.
Bottom line
Choose Zammad if you need enterprise authentication, broad native multi-channel ticketing, and possibly a managed cloud tier — it's the go-to open-source help desk for data-control-focused technical teams. Choose FreeScout if you want the leanest, cheapest self-hosted shared inbox with unlimited agents and a friendly UI, adding capabilities through modules as needed. Enterprise auth and channels: Zammad. Lightweight free inbox: FreeScout.
