Bugzilla — Open-source web-based bug tracking system

Key characteristics

Bugzilla traditionally runs as CGI scripts and is written in a scripting language that makes it portable across environments. Typical installations use a relational database backend and a web server. Common functional strengths include fine-grained permissions, advanced search and saved queries, email notifications, attachments and the ability to define custom fields and workflows.

Main features

• Detailed issue records with status, priority, assignee, and dependencies
• Powerful query language and saved searches for tracking work
• Email-based notifications and workflow events to keep teams informed
• Attachment and patch handling, plus comments and histories for auditability
• Extensions and APIs for automation and integration with other tools

History and development

Originally developed by contributors associated with the Mozilla project in the late 1990s, Bugzilla has evolved through community maintenance and incremental improvements. Its development emphasis has been stability, configurability and strong search capabilities. Over time the project has added modern interfaces, APIs and compatibility with current database backends while retaining the core workflow model.

Uses and deployment

Bugzilla is commonly adopted by open-source projects, enterprise teams and organizations that prefer a self-hosted, open-source issue tracker. Deployments vary from small teams running a single server to larger installations integrated with continuous integration, source control and mailing lists. Administrators can customize fields, permissions and notification rules to match organizational processes.

Distinctive points and resources

Compared with more feature-rich project-management suites, Bugzilla is focused on issue tracking and reliable history rather than integrated planning or agile boards. It is released under an open-source license and can be extended or hosted privately.
