Zammad is a web-based open source helpdesk and customer support system.

Zammad addresses the challenge of managing customer inquiries across multiple communication channels by consolidating support interactions into a single platform. It handles incoming requests through email, chat, telephone, and social media, allowing support teams to coordinate responses and maintain context across all customer touchpoints. The system is built on Ruby on Rails with a modern frontend using Vue.js and TypeScript, and provides a REST API and GraphQL support for integration with other tools.

Organizations managing distributed customer support should consider Zammad if they need an open source alternative to commercial helpdesk platforms and are comfortable self-hosting or using the vendor's cloud service. The tool suits teams that want to avoid vendor lock-in and prefer to own their support infrastructure. The software is licensed under GNU AGPLv3 and owned by the Zammad Foundation, ensuring independence from commercial interests, though Zammad GmbH offers a managed cloud service as an alternative to self-hosting.

The project maintains steady engagement with both internal and external contributors, with maintainers typically responding to new issues and pull requests within a day. Work in the issue tracker is dominated by verified bugs and items prioritized through commercial support channels, indicating that development priorities reflect both community needs and paying customer requirements. The mix of core team and outside user involvement in the open issues suggests the tool has adoption beyond its maintainers without creating an overwhelming external support burden.
