Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Request Tracker (RT)
- Perl stack and configuration via flat files is unfamiliar to modern web developers
- UI is functional but dated; requires theming effort to modernize
- Setup and initial customization have a significant learning curve
Zammad
- Resource-heavy: needs Elasticsearch plus a database, making setup and ops more demanding
- UI feels dated compared to Zendesk/Intercom
- No native modern live-chat widget on par with Intercom
- Smaller marketplace/integration ecosystem than the incumbents
Bottom line
Both are a similar lift to self-host; choose Zammad for the larger community and ecosystem. Zammad has seen more recent development. Open each guide below for deploy steps and the full feature gap.
