In its favor

Why people choose Redmine

The signal that keeps Redmine on the shortlist. Sourced from G2, Capterra, and customer scoping calls.

Free open-source licensing with no per-user or per-project fees makes Redmine popular with budget-constrained technical teams and nonprofits.

Full source-code access and a mature plugin ecosystem let self-hosting teams customize workflows, roles, and integrations without vendor constraints.

Built-in Gantt charts, calendars, time tracking, and version-control repository browsers provide project management essentials out of the box.

Cross-platform and cross-database support (MySQL, PostgreSQL, SQLite) means Redmine runs on a wide range of infrastructure.

Support for 49 languages and per-project wikis and forums appeals to globally distributed or documentation-heavy teams.

Installation and initial configuration are consistently described as difficult, with a steep learning curve for server administrators new to Ruby on Rails.

The user interface is widely criticized as dated and unintuitive, with cluttered project screens and confusing role-based permission setup.

Email notifications lag and feel outdated compared to modern real-time collaboration tools, frustrating teams expecting Slack-style updates.

Performance degrades with large numbers of projects and issues, and no native mobile app forces reliance on a mobile-unfriendly web interface.

Hidden costs accumulate through required hosting fees, paid plugins for enterprise features, and ongoing IT maintenance overhead.

Platform scorecard

Strengths, weaknesses, and where Redmine fits

Grades across six dimensions, plus a SWOT-style view of where the platform shines and where it falls short.

SWOT — strengths, weaknesses, and use-case fit

Strengths

Completely free with no licensing or user-count constraints.Self-hosted with full source-code access and no vendor lock-in.Rich built-in feature set: Gantt charts, time tracking, wikis, forums, VCS integration.Large community plugin ecosystem extending functionality.Supports 49 languages, cross-platform, and multiple databases.

Weaknesses

No native bulk import UI—data entry relies on CSV exports or direct DB access.REST API is read-only by default and must be explicitly enabled by an administrator.Dated, unintuitive interface with steep initial learning curve.No mobile app; mobile web experience is poor.Performance degrades with large data volumes.

Where it works

Small to mid-sized development teams with budget constraints that need free, self-hosted issue tracking without per-user licensing fees.Organizations with in-house Ruby on Rails or Linux server expertise who can handle installation, configuration, and ongoing maintenance.Technical teams that require full source-code access to customize workflows, roles, and integrations to fit specific regulatory or compliance needs.Distributed teams operating in regulated industries such as healthcare or finance that require VPN-accessible, on-premises data storage rather than cloud-hosted tools.Project-driven organizations needing basic time tracking, Gantt charting, and version-control repository browsing bundled together without paying for premium plugins.

Where it struggles

Large organizations with hundreds of concurrent projects and issues experience performance degradation without significant infrastructure tuning.Teams expecting modern, mobile-friendly interfaces or real-time collaboration features will find the dated UI and laggy email notifications frustrating.Non-technical users or teams without server administration resources face steep onboarding curves for installation, database migration, and plugin management.Organizations requiring rapid deployment without dedicated IT staff struggle with Redmine's manual setup, Ruby-on-Rails dependencies, and configuration overhead.Enterprises needing native bulk-import tooling or read-write REST APIs out of the box will hit limitations since the API is read-only by default and requires admin-level enablement.

What gets migrated

Redmine object support

Object-by-object support for Redmine migrations. Per-pair details surface during scoping.

Projects

Fully supported

Projects and subprojects map cleanly. We pull the full project hierarchy via the REST API or direct DB access and recreate parent-child relationships in the destination. No special handling required.

Issues

Mapping required

Issues are the core object. We map standard fields (status, priority, tracker, assignee, due date) and handle custom fields as a separate step. Note that CSV export excludes history—a full issue history requires DB-level extraction or a plugin.

Time Entries

Fully supported

Time entries are first-class objects linked to Issues and Users. We export them via CSV or the REST API and map them to equivalent time-logging objects in the destination PM tool.

Users

Mapping required

Redmine Users include login, name, email, admin flag, and custom fields. We preserve the user identity but note that Redmine does not store a password hash compatible with most SaaS destinations, so credential migration is not possible.

Custom Fields

Mapping required

Custom Fields are defined separately via /custom_fields.json and apply to specific object types (issue, project, time_entry). We retrieve all definitions first, then map values per object during migration.

Wiki Pages

Mapping required

Wiki pages are stored as separate objects with wiki text and attachments. Migration requires preserving the content format and file references, which may not be compatible with destination wikis.

Documents

Mapping required

Documents are project-level file attachments with titles and descriptions but no direct Issue linkage. We map them as files in the destination project context.

Versions

Fully supported

Versions (also called milestones) are straightforward to map. They carry a name, description, status, and due date that transfer cleanly to destination Versions or Milestones.

Enumerations

Mapping required

Enumerations cover issue statuses, priorities, document categories, and activities. We map the active enumeration values; deprecated values are omitted unless explicitly requested.

News

Mapping required

News entries are lightweight posts tied to projects. We migrate the title, description, and author but note that the 'news' concept does not exist in most SaaS PM tools and typically gets mapped to project announcements or dropped.

Attachments

Mapping required

Attachments are stored both in the database (metadata) and on the filesystem under Redmine's /files directory. We retrieve both layers and re-upload files to the destination, preserving filename and content.

Groups

Mapping required

Groups are used to organize Users for role assignment. We recreate Groups in the destination and repopulate their membership. Note that some destination tools do not have a Group object and require flattening to individual user permissions.

Trackers

Mapping required

Trackers (Bug, Feature, Support, etc.) are enumerations that categorize Issues. We map Tracker names and custom tracker definitions, noting that destination tools may use different taxonomy for issue types.

How a Redmine migration works

Four steps, Redmine-specific

Connect

API key or session cookie (admin required for most endpoints) into Redmine. Scopes limited to read-only on the data we move.

Map

We translate Redmine-specific structures (custom fields, objects, value lists) to the destination's model.

Sample

Test with a 50–200 record subset to validate Redmine quirks before production.

Migrate

Full migration with Redmine rate-limit handling. Rollback available throughout.
