Bugzero

Bugzero is a web-based bug, defect and issue tracking system published by WebSina. It also covers change management, requirements, use case and test case management, help desk and customer tracking. Fields, workflows and permissions are configurable per project without programming, and issues can be submitted and followed by e-mail.

Bugzero is written in Java and runs on a Java application server (Tomcat, WebLogic, WebSphere) on Windows, Unix, Linux or Mac OS with Oracle, DB2, SQL Server, Sybase, MySQL, PostgreSQL or Access. It is sold with one-time licences or as a hosted service; a free version is limited to 100 bug reports and five users.
