About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Zammad is a web-based helpdesk and customer-support platform that turns requests from email, chat, telephone, and other channels into shared tickets. Teams can coordinate ownership, status, priority, customer history, and integrations through a common workflow and REST API.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Bring multiple support channels into one ticket queue

Requests from email, chat, telephone, and other channels can be handled through one ticket model with shared ownership, state, and history.

Sources: [2][4]

Share support history and customer context across a team

Ticket history and assignments reduce knowledge trapped in personal mailboxes and make handoffs and duplicate-response avoidance easier.

Sources: [2][4]

For self-hosted customer support and internal helpdesk workflows

Zammad fits teams that need assignment, search, history, and API integration around a growing volume of support requests.

Sources: [2][4]

Plan search, backups, upgrades, and AGPL obligations

The official Docker Compose stack uses PostgreSQL and enables Elasticsearch by default. Operations include backups and upgrades, and modified network-service deployments should review AGPL-3.0 requirements.

Supplemental curator note

Zammad fits support teams that want shared ownership, status, and history instead of handling requests in individual mailboxes. The project is AGPLv3; organizations running modified versions as network services should review the source-availability obligations in that license.
