OpenProject vs Taiga: Which Should You Self-Host?

Quick Verdict

Taiga is the better choice for agile software teams that follow Scrum or Kanban. OpenProject is the better choice for organizations that need Gantt charts, resource planning, cost tracking, and traditional project management alongside agile boards.

Overview

Both are mature, open-source project management platforms with active development. OpenProject (GPLv3, started 2012) focuses on enterprise project management with Gantt charts as a headline feature. Taiga (MPL 2.0, started 2014) focuses on agile methodology with sprint planning, backlogs, and user stories as its core.

Official Docker supportYes (well-maintained)Yes (official repo)

OpenProject wins on setup simplicity. The all-in-one image bundles PostgreSQL and Memcached — one container, two volume mounts, running in minutes. Taiga’s microservices architecture (9 containers: backend, frontend, two RabbitMQ instances, events server, async worker, protected file server, Nginx gateway, PostgreSQL) is more complex but handles separation of concerns well.

Performance and Resource Usage

MetricOpenProjectTaiga
RAM (idle)~800 MB (all-in-one)~1.5 GB (9 containers)

Disk (base)~1 GB~2 GB
Minimum recommended4 GB RAM, 4 cores2 GB RAM, 2 cores
Scales to1,500+ users (with tuning)Hundreds of users

OpenProject is heavier per-instance because it’s a single monolithic Rails app doing everything. Taiga’s microservices add up to more total RAM but each individual service is lighter. For small teams (<20 users), Taiga is more efficient. For large organizations, OpenProject scales better with its tunable worker model.

Taiga is fully open source with no paid enterprise tier — every feature is available in the community edition. OpenProject gates some features (resource planning, advanced authentication, team planners) behind its Enterprise plan.

Use Cases

Choose OpenProject If…

  • You need Gantt charts — this is OpenProject’s killer feature and Taiga doesn’t have them
  • You manage projects with budgets, cost tracking, and time reporting
  • Your organization follows traditional/hybrid project management (waterfall + agile)
  • You need meeting management integrated with project tracking
  • You need a calendar view for deadlines and milestones
  • You want the simplest Docker setup (one container, done)

Choose Taiga If…

  • Your team follows Scrum with sprints, backlogs, and burndown charts
  • You want a cleaner, more intuitive UI that non-technical team members can use immediately
  • You need full agile features without paying for an enterprise tier
  • You want a more permissive license (MPL 2.0 vs GPLv3) for integration into other products
  • Your team is small-to-medium and doesn’t need Gantt charts or cost reporting
  • You want epics and user stories as first-class objects (not generic “work packages”)

Final Verdict

These tools target different project management styles. OpenProject is a traditional project management platform that also does agile. Taiga is a pure agile platform.

For most software teams doing Scrum or Kanban, Taiga is the better fit — its sprint planning, backlog management, and burndown charts are more refined than OpenProject’s agile features. The UI is cleaner and team adoption is easier.

For project managers who need Gantt charts, budgets, resource allocation, and meeting minutes alongside basic agile boards, OpenProject is the clear choice. It’s the closest self-hosted equivalent to Jira + Microsoft Project combined.

If neither fully fits — you just need a simple Kanban board without the overhead — look at Planka or Plane.
