Bugzilla vs MantisBT

Bugzilla is a self-hosted, web-based system for tracking defects, issues, enhancements, and other product change requests. It is free and open source, and runs on Linux, macOS, and Windows, with API access. Its search ranges from full-text queries to advanced searches, including time-based criteria. Users can choose which bug-change emails they receive, and scheduled search reports can be sent as often as every fifteen minutes. Reports can include tables and graphs, and can be exported as CSV. Administrators can tailor workflows, statuses, resolutions, and fields, then extend an installation with templates and extensions. Groups control who can view or edit bugs; an insider group can make comments and attachments private. Bugzilla supports XML-RPC and JSON-RPC services, several authentication methods, and MySQL, PostgreSQL, or Oracle databases. Its Patch Viewer connects with LXR, CVS, and Bonsai. Support is community-based through mailing lists and chat rooms; the project does not directly provide commercial support.

MantisBT is a free, open-source bug tracking system built on PHP for use through a web server. It is released under the GNU General Public License and can run on Linux, Windows or macOS servers. Installation requires PHP and a supported database; listed database options are MySQL, MS SQL and PostgreSQL. Project tools include change logs, roadmaps, time tracking and reporting. Teams can configure workflow transitions and access thresholds, and email notifications can include issue changes, notes, custom fields and issue details. Plugins from official and third-party developers extend the system. Its REST API is the primary web-services integration route, with API tokens, enabled anonymous access or web UI cookie sessions available for authentication. Listed browser support includes Chrome, Firefox, Safari, Opera and Edge. Community help includes documentation, forums, a bug tracker, wiki and chat. For teams seeking hosting, MantisBT presents MantisHub as a separate service with backups, upgrades, support, migration and add-ons; its trial requires no credit card.
