Pricing and feature comparison: OpenProject Professional vs Redmineflux Cloud for a 25-person team.
Four meaningful differences between two open-source peers.
Shared lineage, different architecture, different plugin ecosystems. The differences compound at the edges of the operations loop.
Platform vs plugin layer.
OpenProject is a standalone platform that replaces Redmine. Redmineflux is a plugin suite that extends the Redmine already in use. For teams already invested in Redmine – data, custom workflows, existing integrations – Redmineflux is the lower-risk path. Choosing OpenProject means re-platforming.
Core modules vs focused stack.
OpenProject extends its capabilities through core modules – Agile, Time/Costs, Budgets, Forums, Meetings. These are comprehensive for project delivery. There is no equivalent of Redmineflux’s 20-plugin focused stack: no helpdesk, no CRM, no invoice generation from time logs. Redmineflux fills gaps that OpenProject leaves open at both ends of the operations.
No AI vs MCP Server.
Redmineflux has an MCP Server that connects Claude Code, Cursor, and custom AI agents directly to Redmine – allowing AI to read, create, and update Redmine issues. OpenProject lists MCP integration as a Professional-tier add-on as of 2026-07-13; verify its current scope and availability at openproject.org/pricing. For teams evaluating AI-assisted development workflows, verify the depth of each tool’s MCP offering before deciding.
Per seat vs per plan.
OpenProject Community self-hosted is free, matching Redmine (also free). On Cloud, OpenProject charges per seat from €5.95/user/month (Basic, 25-user minimum). Redmineflux Managed Cloud charges per plan (Gold/Platinum/Diamond), not per user. For teams of 25+, Redmineflux Cloud’s flat structure becomes increasingly cost-efficient relative to OpenProject’s per-seat model.
Moving between OpenProject and Redmine + Redmineflux.
The shared data model makes this the most structurally compatible tool pair in this comparison series. Both use structured tickets as the unit of work.
- 1
Export from OpenProject
Use OpenProject’s REST API export or CSV work package export. Work packages, assignees, statuses, priorities, and custom fields are exportable. The data model maps closely to Redmine issues.
1–2 days - 2
Map work packages
Map OpenProject work package types to Redmine trackers. Statuses, priorities, and custom fields have direct equivalents in Redmine. Map OpenProject projects to Redmine projects.
1–2 days - 3
Import to Redmine
Import the mapped CSV into Redmine using Redmine’s CSV import with field mapping. The structural similarity means this is among the cleanest migrations in the open-source PM space.
1–2 days - 4
Install Redmineflux plugins
Install the Redmineflux plugins that replace OpenProject capabilities your team was using. Agile Board replaces OpenProject Agile Boards; Gantt Chart Plugin replaces the Gantt timeline.
1–3 days - 5
Parallel run & cutover
Run both systems for 30–60 days. New issues go into Redmine + Redmineflux. Once the team is confident, decommission OpenProject as the primary system.
30–60 days
The honest version.
Both tools are mature and genuinely capable. The right choice turns on whether you are already on Redmine, and whether you need CRM, helpdesk, or AI integration.
OpenProject is the right choice.
- Your team is evaluating from scratch and has no existing Redmine installation
- You want a unified open-source PM platform without the complexity of a plugin ecosystem
- EU data residency is mandatory and you prefer a European-hosted Cloud option
- Your workflow fits OpenProject’s module set without needing CRM, invoicing, or helpdesk
- Community support is sufficient and you want zero licence cost on self-hosted
Redmineflux is the right choice.
- Your team is already on Redmine – migrating to OpenProject means re-platforming your issue data
- You need helpdesk, CRM, or invoice generation alongside project management
- AI-assisted workflow (MCP Server, Claude integration) is a current or near-term requirement
- You want a focused plugin stack maintained by one vendor against specific Redmine versions
- Flat per-installation pricing is preferable to per-seat Cloud pricing as the team grows
Questions about OpenProject vs Redmineflux.
Five questions that come up in every evaluation of open-source PM tools. If yours isn’t here, check pricing or contact support.
Is OpenProject compatible with Redmineflux plugins?+
No. OpenProject and Redmine are different platforms. Redmineflux plugins are built for Redmine and do not run on OpenProject. If you are on OpenProject and want Redmineflux, you would need to migrate your data to Redmine first.
Does OpenProject have Kanban boards?+
Yes. OpenProject has an Agile Board module that supports Kanban and Scrum boards with sprint management. This is comparable in depth to the Redmineflux Agile Board Plugin. Both tools cover this capability well.
Which has better Gantt support?+
Both OpenProject and Redmineflux offer Gantt charts with dependencies, milestones, and timeline views. Both are strong. OpenProject’s Gantt is included in the Community (free) tier; the Redmineflux Gantt Chart Plugin is a paid plugin available per installation.
Does Redmineflux have EU data residency on Cloud?+
Redmineflux Managed Cloud infrastructure is configurable by region. Contact the team to confirm current data residency options for your region. On self-hosted, the team controls data residency entirely – deploy on any infrastructure, in any region.
Which Redmine versions does Redmineflux support?+
All Redmineflux plugins are tested and maintained against the three most recent stable Redmine releases. Compatibility is verified with each update. Check the documentation for the confirmed supported version list before installing.
