JTrac vs Redmine

JTrac is a free, open-source issue-tracking web application written in Java and licensed under Apache Software License 2.0. It tracks bugs, action items, and tasks using project-specific fields and workflows. Administrators can set project roles, workflow states, and field-level permissions. Each project space supports up to 10 dropdown fields, 5 free-text fields, 3 numeric fields, and 3 date/time fields. Work tools include item history, file attachments, full-text search, custom-field filtering, dashboards, and Excel export. Status changes trigger email notifications by default, with SMTP configured by an administrator. Authentication options include LDAP, Active Directory, and CAS single sign-on; LDAP handles authentication only, so administrators must also create users and assign them to project spaces. JTrac requires Java 8 or higher, and a JRE is sufficient. It can use its embedded web server and database or be deployed as a WAR in a servlet 3.1 compliant container. The project lists developers, end users, IT, and quality engineers as its intended audience.

Redmine is an open-source web application for managing projects, available for self-hosting. A single instance can manage multiple projects, each with its own roles, visibility settings, and enabled modules. Teams can define issue statuses and types, then set workflow transitions by issue type and role. Gantt charts and calendars use issue dates for planning, and time entries can be reported by user, issue type, category, or activity. Collaboration tools include project wikis and forums, news, document and file management, feeds, and email notifications. The repository browser supports Subversion, CVS, Mercurial, Bazaar, and Git. Its REST API provides basic create, update, and delete operations for documented resources in XML and JSON. Redmine is released under GNU GPL v2 and costs nothing for self-hosting. It should run on most Unix, Linux, macOS, and Windows systems where Ruby is available, but it does not support JRuby. The project directs users to forums and IRC for help and discussion. The download page identifies the 7.0.x branch as the latest stable version, with new features, bug fixes, and security updates.
