Best Open Source Project Management Tools

How We Evaluated These Tools

Selecting the best open source project management tools requires looking beyond feature lists. We evaluated each platform on five criteria: core functionality (issue tracking, boards, planning), deployment simplicity (Docker support, documentation quality), community health (commit frequency, contributor count, issue response times), extensibility (API quality, plugin support, integrations), and real-world adoption (production deployments, user testimonials, enterprise references). Only tools with active development, transparent licensing, and functional self-hosted editions made this list.

OpenProject: Best for Comprehensive Project Planning

OpenProject is the most feature-complete open source project management platform available. It serves organizations that need to manage complex projects with dependencies, milestones, resource allocation, and cross-project visibility. The Community Edition ships with everything a mid-size team needs: work package tracking with customizable types and statuses, Gantt charts with drag-and-drop scheduling and predecessor relationships, Scrum and Kanban boards, built-in time tracking with cost reporting, roadmap and release planning, and a wiki per project.

What sets OpenProject apart is its ability to handle both traditional waterfall and agile methodologies within a single project. A product team can run sprints on a Kanban board while the PMO tracks milestones and dependencies on a Gantt timeline, with both views reflecting the same underlying work packages. This dual-methodology support makes OpenProject the natural choice for organizations where different teams follow different processes.

The deployment infrastructure is mature and well-documented. Docker Compose is the recommended approach, with separate containers for the application, PostgreSQL database, and background workers. OpenProject GmbH maintains detailed installation guides, migration scripts, and a responsive community forum. The Enterprise edition adds LDAP and SAML authentication, two-factor authentication, and professional support, but the Community edition is genuinely complete for teams that do not need enterprise SSO.

Plane: Best for Modern Software Teams

Plane has gained rapid adoption since its launch by delivering a project management experience that feels more like Linear or Notion than traditional PM software. Built with Next.js on the frontend and Django on the backend, Plane prioritizes speed, keyboard navigation, and visual clarity. The interface is clean and responsive, with everything accessible through a command palette and shortcuts that engineering teams expect from modern tools.

Core features include issue tracking with customizable properties, cycles (time-boxed iterations similar to sprints), modules for grouping related work across cycles, a built-in wiki with real-time collaborative editing, and timeline views for visualizing project schedules. Plane supports labels, priorities, estimates, and custom views that let each team member organize their work the way they prefer.

The self-hosted Community Edition has no artificial feature restrictions. You get the full platform with unlimited users, projects, and storage. The commercial Cloud and Enterprise editions add advanced analytics, priority support, and AI-powered features that are still in active development. Plane's architecture uses Docker Compose for deployment, with well-maintained documentation and an active Discord community for troubleshooting.

Plane's development velocity is notable. The project ships frequent updates with meaningful feature additions, and the team actively incorporates community feedback into the roadmap. For teams that want a tool that will continue improving rapidly, Plane's trajectory is compelling.

Taiga: Best for Agile and Scrum Teams

Taiga is built from the ground up for agile project management. Where other tools add Scrum support as a layer on top of a generic issue tracker, Taiga's entire architecture reflects the Scrum framework. The backlog view lets product owners prioritize user stories, assign story points across multiple roles (front-end, back-end, design, QA), and drag items into sprints. During sprints, the taskboard shows each story broken down into tasks with real-time status tracking. Burndown charts, velocity graphs, and sprint retrospectives are first-class features, not afterthoughts.

Kanban is equally well-implemented, with customizable columns, WIP limits, and card aging indicators. Teams can choose Scrum, Kanban, or a hybrid approach at the project level. Taiga also supports issues (bugs and requests) as a separate workflow from stories, which keeps the product backlog clean while still tracking defects and support requests.

The interface emphasizes simplicity and visual appeal. Taiga consistently receives praise for being accessible to non-technical team members, including designers, product managers, and stakeholders. The learning curve is minimal compared to OpenProject or Redmine, making it a strong choice for cross-functional teams where not everyone has a software engineering background.

Redmine: Best for Stability and Plugin Ecosystem

Redmine has been in active development since 2006, making it one of the longest-running open source project management platforms. Its core is deliberately minimal, providing issue tracking with customizable trackers, statuses, and workflows, time tracking, a wiki per project, forums, document management, and multi-project support with cross-project issue relationships. What makes Redmine exceptional is its plugin architecture, with hundreds of community-contributed extensions that add everything from agile boards (Redmine Agile plugin) to CRM, help desk, and advanced Gantt charts.

This maturity comes with trade-offs. The default interface looks dated compared to Plane or Taiga, and the out-of-the-box agile support requires plugins. However, for organizations that value long-term stability, a proven track record in enterprise environments, and the ability to extend the platform in virtually any direction, Redmine remains a reliable foundation. Some organizations have run Redmine instances for over a decade with thousands of projects and hundreds of thousands of issues.

License: GNU GPL v2. Language: Ruby on Rails. Database: MySQL, PostgreSQL, SQLite. Best for: Organizations that need a proven, stable platform with extensive plugin-based customization and do not prioritize modern UI design.

Leantime: Best for Non-Technical Teams

Leantime is designed for people who manage projects but are not project managers by training. Built on PHP and MySQL, it offers Kanban boards, task lists, calendar views, timesheets, and a project wiki. What makes it unique is its inclusion of strategic planning tools, including Lean Canvas for business model mapping, SWOT analysis, idea boards, and goal tracking that connects daily tasks to business objectives.

The open source edition has no feature gates. Everything ships for free, including the strategic planning tools that would typically be locked behind an enterprise tier in other products. Leantime's interface is intentionally gentle, with guided workflows and language that avoids project management jargon. It was designed with neurodivergent users in mind, incorporating behavioral science principles to help users maintain focus and follow through on tasks.

Deployment requires a standard LAMP stack or Docker, making Leantime one of the simplest tools to self-host. PHP hosting is widely available and affordable, which lowers the barrier for small organizations that do not have Kubernetes expertise.

License: AGPL v3. Language: PHP. Database: MySQL. Best for: Startups, creative agencies, and non-technical teams that want strategic planning tools alongside day-to-day task management.

WeKan: Best Lightweight Kanban Board

WeKan is a privacy-focused, open source Kanban board that prioritizes simplicity and data sovereignty. Built on Meteor, it offers customizable boards with multiple card types, swimlanes, checklists, due dates, labels, and member assignments. Access controls let administrators restrict board visibility and editing permissions. WeKan supports LDAP authentication, making it suitable for organizations with existing directory services.

WeKan is available as a Snap package for Ubuntu, which means installation is a single command. It also supports Docker and various PaaS platforms. The project is actively maintained and has a dedicated community of self-hosting enthusiasts who value its focused approach to Kanban without the complexity of a full project management suite.

License: MIT. Language: Meteor (JavaScript). Database: MongoDB. Best for: Teams that want a standalone Kanban board with strong privacy controls and minimal maintenance requirements.

Choosing Between These Tools

The right tool depends on your team's methodology, technical capacity, and organizational context. Teams leaving Jira that need feature parity should start with OpenProject. Software teams that prioritize developer experience should evaluate Plane. Scrum teams should look at Taiga first. Teams that need maximum extensibility and long-term stability should consider Redmine with appropriate plugins. Non-technical teams benefit most from Leantime's accessible interface. And teams that just need a board to visualize work should try WeKan or Kanboard.

Regardless of which tool you choose, deploy it in a test environment first and run a real project through it for at least two weeks before committing. The best tool is the one your team actually uses consistently.
