Redmine

Redmine is a free, open-source web application for managing projects, issues and development work on infrastructure you control. It is best for teams that need detailed, project-specific workflows and repository visibility, provided they can operate a Ruby-based installation. The trade-off is ownership of deployment, upgrades and support rather than a vendor-managed service.

Overview

A single Redmine instance can run multiple projects while giving each project its own roles, visibility rules and enabled modules. That shared-but-separate structure suits organisations with varied teams or clients that need different access policies without maintaining separate systems. Redmine is licensed under the GNU General Public License v2 and maintained by community volunteers; help is centered on forums and an IRC chatroom, so teams must be prepared to handle administration and troubleshooting themselves.

The application is cross-platform and cross-database, and is intended to run on most Unix, Linux, macOS and Windows systems where Ruby is available. JRuby is not supported. This gives administrators broad hosting choices, but the Ruby prerequisite remains a meaningful operational constraint.

Key features

Project and issue control

Administrators can define issue statuses and types, then restrict workflow transitions by issue type and role. In practice, that supports disciplined approval or triage processes and lets different projects follow different rules. The benefit depends on maintaining those configurations as processes change; Redmine gives control rather than a ready-made methodology.

Planning and time reporting

Gantt charts and calendars are generated from issue dates, giving teams schedule views connected to actual work items. Users can enter time and report it by user, issue type, category or activity. This is useful for capacity reviews, project accounting and retrospective analysis, although the value of the reports relies on consistent time entry.

Collaboration and records

Project wikis, forums, news, documents, files, feeds and email notifications keep discussion and reference material alongside project work. These modules make Redmine more than an issue register, particularly for teams that want project knowledge stored in the same system. Each project can enable only the modules it needs, limiting clutter for simpler engagements.

Repositories, identity and API

The repository browser covers Subversion, CVS, Mercurial, Bazaar and Git, making Redmine a practical hub for teams using different version-control systems. Authentication can connect to multiple LDAP directories, with optional online self-registration. A REST API supports documented resources and basic create, update and delete operations in XML and JSON, enabling integrations without replacing Redmine's core workflow.

Maintenance and security

Redmine publishes security advisories for vulnerabilities fixed in releases. The download page identifies the 7.0.x branch as the latest stable line, while older branches receive narrower support or are unsupported. Self-hosting therefore includes a real upgrade and security-maintenance obligation.

Pricing

There are no per-seat charges or hosted subscription terms in this plan. The economic advantage is strongest for organisations that already have the people and infrastructure to install, secure and update software. It is less suitable for teams that would need to buy external administration or want a guaranteed vendor-operated environment; those costs sit outside the licence.

Platforms

Redmine is available as a web application with support for Linux, macOS and Windows hosting where Ruby is available, plus API access and self-hosted deployment. It does not support JRuby. There are no native mobile platforms stated, so mobile use depends on access to the web application or an integration.

Who it's for

Redmine fits software and IT groups that need configurable issue workflows, Gantt and calendar planning, detailed time reports, project-level permissions and built-in browsing for Git or other repositories. It also suits organisations consolidating several projects on one controlled installation, especially where LDAP integration matters. Look elsewhere if you need a vendor to run the service, a mobile-first experience, or support beyond community forums and IRC.

Pros and cons

Pros

• Deep project-level control: roles, visibility and modules can differ by project within one instance.
• Configurable workflows: statuses, issue types and role-based transitions can reflect formal processes.
• Broad development coverage: repository browsing spans Git, Subversion, CVS, Mercurial and Bazaar.
• Strong reporting foundation: issue-linked schedules and multi-dimensional time reporting support planning and accountability.
• No licence fee: the GPLv2 self-hosted plan avoids per-user subscription costs.

Cons

• Operational responsibility: your team supplies the Ruby environment, deployment, upgrades and security maintenance.
• JRuby exclusion: environments standardized on JRuby cannot run Redmine.
• Community-led support: assistance is directed to forums and IRC rather than a stated vendor support service.
• Configuration overhead: flexible workflows and project modules require ongoing administration to stay useful.

Alternatives

Choose Asana instead if you want a freemium service with Android, iOS, macOS and Windows clients; its Personal plan is free forever for one or two people, with two users and a 100 MB maximum file size.

ClickUp is the better fit when a hosted freemium workspace and generous task access matter: its Free Forever plan includes unlimited tasks and members, 60 MB of storage and one form.

Pick Linear for a hosted, developer-oriented option with unlimited members, two teams and 250 issues on its free plan, plus API and desktop/web platforms.

Wrike suits teams wanting hosted work management with unlimited users, 2 GB of account storage and 200 active tasks on its free plan.

Consider YouTrack when a cloud service for up to 10 users and 30 GB of storage is preferable.

Azure Test Plans is an alternative for teams specifically seeking integrated test planning at $52 per user per month on its Basic + Test Plans plan.

Teamwork.com offers hosted project management with a free tier for five projects and five users.

monday.com is a hosted visual-workspace alternative with a free tier capped at two seats, three boards, three Docs, 200 items and 500 MB of storage.

For broader comparisons, browse IT Project Management Software, Game Bug Tracking Software, Game Project Management Software, Issue Tracking Software or Project Management Software.

Verdict

Redmine is a strong choice for technically capable organisations that want free, self-hosted control over multiple projects, issue workflows, time reporting and source repositories. Choose it for configurability and licence economics; look elsewhere when operating Ruby infrastructure, maintaining releases and relying on community support would outweigh the value of owning the system.
