Taiga vs OpenProject: Agile PM Compared

Quick Verdict

Both are serious project management platforms, but they target different workflows. Taiga is built for agile software teams — Scrum sprints, backlogs, user stories, and a clean UI that non-engineers can use without training. OpenProject covers traditional project management too — Gantt charts, work packages, cost reporting, meeting agendas, and document management. If your team runs Scrum or Kanban sprints, Taiga is the leaner choice. If you need Gantt-heavy planning with time and cost tracking, OpenProject has more depth.

Overview

Taiga is an open-source agile platform with Scrum and Kanban support. It runs as a microservices stack — 9 containers including Django backend, Node.js events server, async worker, PostgreSQL, and RabbitMQ. The interface is intentionally opinionated: it does agile well and doesn’t try to be an everything-PM tool. MPL-2.0 license.

OpenProject is a comprehensive project management platform with Gantt charts, agile boards, time tracking, cost reporting, wiki, meeting management, and document storage. It runs as a single all-in-one container with PostgreSQL and memcached included. The community edition is free; enterprise features (LDAP groups, 2FA) require a paid plan. GPL-3.0 license.

Feature Comparison

Feature	Taiga	OpenProject
Scrum (sprints, backlogs)	Yes (first-class)	Yes
Kanban boards	Yes	Yes
Gantt charts	No	Yes (interactive, drag-and-drop)
User stories	Yes (with points)	Yes (work packages)
Epics	Yes	Yes
Time tracking	No	Yes (built-in)
Cost reporting	No	Yes (budgets, labor rates)
Wiki	Yes	Yes
Meeting management	No	Yes (agendas, minutes)
File storage	Attachments only	Yes (document management)
Calendar	No	Yes
Notifications	Yes (email + in-app)	Yes (email + in-app)
Custom fields	Yes	Yes
Workflow automation	Limited	Yes (workflow designer)
API	REST	REST + JSON:API
Webhooks	Yes	Yes
LDAP/SSO	Community plugin	Enterprise only
Mobile app	No (responsive web)	No (responsive web)
Import from Jira	Yes	Yes
Import from Trello	Yes	No
License	MPL-2.0	GPL-3.0

Installation Complexity

Aspect	Taiga	OpenProject
Docker containers	9 (backend, frontend, events, async, PostgreSQL, RabbitMQ, proxy, etc.)	1 (all-in-one image)
Pre-built images	Yes (taigaio/*)	Yes (openproject/openproject)
External database	PostgreSQL (included in stack)	PostgreSQL (included in image)
Setup time	30-40 minutes	15-20 minutes
Config method	Environment variables	Environment variables
SMTP required	Recommended	Recommended

OpenProject’s all-in-one image (openproject/openproject:15) bundles PostgreSQL, memcached, web server, and worker processes in a single container. This makes deployment simpler but makes debugging harder — if something fails, you’re looking at logs from multiple processes in one container.

Taiga’s 9-container microservices architecture is more complex to deploy but each service is independently restartable and monitorable. The official Docker Compose template is well-documented.

Performance and Resource Usage

Metric	Taiga	OpenProject
Minimum RAM	2 GB	4 GB
Recommended RAM	4 GB	8 GB
Idle RAM	~800 MB (all containers)	~1.5 GB
CPU cores	2	2-4
Disk space	3 GB base	20 GB base
Max users (community)	Unlimited	200 (recommended)

OpenProject is the heavier platform — its Ruby on Rails backend, document storage, and built-in search index consume more resources. Taiga’s Django backend is lighter per-container but the 9-container stack adds up.

Community and Support

Aspect	Taiga	OpenProject
GitHub stars	17,000+	9,500+
Backing	Community + Kaleidos	OpenProject GmbH (German company)
Release pace	Quarterly	Monthly
Documentation	Good	Excellent
Paid support	No	Yes (enterprise plans)
Community	Active (forum, Matrix)	Active (community forums)

OpenProject has commercial backing with enterprise support plans, which matters for organizations that need SLAs. Taiga is community-driven with strong open-source roots.

Use Cases

Choose Taiga If…

• Your team runs Scrum sprints with backlogs and story points
• You want a clean agile UI non-engineers can use immediately
• You don’t need Gantt charts or time tracking
• 9-container complexity doesn’t bother you
• You want MPL-2.0 licensing (less restrictive than GPL)
• You’re replacing Jira for an agile team

Choose OpenProject If…

• You need Gantt charts for project planning
• Time tracking and cost reporting are requirements
• Meeting management and document storage add value
• You want an all-in-one deployment (single container)
• Your organization may need enterprise support later
• You’re replacing MS Project, Asana, or Monday.com

Final Verdict

For agile software teams running Scrum or Kanban, Taiga delivers a focused, beautiful experience with less overhead. It does agile well and stays out of the way for everything else.

For organizations needing traditional project management alongside agile — Gantt charts, budgets, time tracking, meetings, documents — OpenProject covers more ground. The enterprise upgrade path is a practical advantage for companies that may need vendor support.

Neither is lightweight. Both require 2-4 GB RAM and dedicated server resources. If you need something simpler, Planka (Kanban only) or Vikunja (task management) run on a fraction of the resources.

FAQ

Can I switch between Scrum and Kanban in both tools?

Yes. Taiga lets you create Scrum or Kanban projects (or switch mid-project). OpenProject supports agile boards alongside its traditional work package views.

Do either support Jira import?

Both support Jira import. Taiga also imports from Trello, Asana, and GitHub. OpenProject imports from Jira and CSV.

Which is better for non-technical teams?

Taiga’s UI is simpler and more intuitive for people unfamiliar with project management tools. OpenProject has more features but a steeper learning curve — it resembles Jira more than Trello.
