Open source project management platform combining issues, wikis, and AI agents in one workspace. Available on cloud, self-hosted, and air-gapped deployments.

Plane is an open source project management platform that combines issue tracking, documentation, and AI-powered workflows into a single workspace. It's built for software teams that want the flexibility of self-hosting without giving up the polish of tools like Jira or Linear. Projects, wikis, cycles, and dashboards all live in one place, and the AI layer is woven throughout rather than bolted on afterward.
The AI side is genuinely central to how Plane works. Plane AI reads across your entire workspace, including projects, cycles, docs, and threads, so you can ask it about blockers, cycle status, or recent doc changes and get answers grounded in your actual data. Built-in agents can triage incoming requests, assign owners, and post updates automatically. There's also a Slack integration that lets you describe work in a channel and have Plane create, assign, and track it without switching tools.
For teams managing work across different roles, Plane offers board, spreadsheet, list, and Gantt views. Cycles handle time-boxed sprints with burndown charts and velocity tracking built in. Initiatives and epics let you roll team-level work up to org-level goals. Dashboards populate automatically from live data, so there's no manual reporting.
Self-hosting is a first-class option. Plane supports Docker and Kubernetes deployments and includes a God Mode admin panel for configuring SSO, SAML, LDAP, SMTP, and workspace security. Air-gapped environments are explicitly supported, which is rare among modern project management tools. If you're comparing open source alternatives, that air-gap support is a meaningful differentiator.
For teams migrating from Jira, ClickUp, Asana, or Monday, Plane offers full data migration including issues, attachments, comments, and automations. The open API, webhooks, OAuth apps, and a native MCP server make it extensible for teams that want to build custom integrations or AI agents on top of the platform. Projects-as-Code via YAML definitions lets engineering-oriented teams version and deploy project configuration from Git.

Self-hostable project management tool with Kanban boards, calendars, and table views, built for teams using Mattermost or standalone.

Important: This repository is currently not maintained.
Focalboard is a self-hosted project management tool that organizes tasks and projects using boards, lists, and cards. It's built for teams who want to keep their work data on their own infrastructure rather than relying on a third-party SaaS platform.
It comes in two forms: a standalone desktop and server app, and an integrated plugin for Mattermost. The Mattermost integration is particularly useful for teams already using that platform for messaging, since boards live alongside conversations without requiring a separate login or tool.
The core interface will feel familiar if you've used tools like Trello or Notion. You can switch between multiple views of the same data:
Each card supports properties like assignees, status, priority, dates, and custom fields. You can filter and group cards by any property, which makes it practical for sprint planning, bug tracking, content calendars, or general project tracking.
Because it's self-hosted, your data stays on your servers. There's no usage cap, no per-seat pricing, and no vendor lock-in. Teams with compliance requirements or data sovereignty concerns get full control over storage and access.
Focalboard is written in Go and React, and it supports SQLite for small deployments or PostgreSQL for larger ones. The standalone personal edition runs as a local desktop app, making it a solid option for individuals who want a private, offline-capable task board without any cloud dependency.
Open-source Kanban board solution offering visual task management, self-hosting capabilities, and robust security features for teams and individuals.

WeKan is a powerful open-source Kanban board platform that puts you in complete control of your project management workflow. Built with privacy and security at its core, this self-hosted solution offers everything you need to organize tasks visually without compromising your data.
Core Features:
Security Advantages:
Migration Support: Includes tools for importing from other platforms, with special focus on Trello data migration as restrictions tighten on free accounts.
Perfect for teams and organizations requiring visual project management with complete control over their data infrastructure and security policies.
Combines task management, time tracking, Pomodoro focus sessions, and GitHub/Jira integration in a local-first app for Windows, macOS, Linux, Android, and iOS.

Super Productivity is a task management app built around the idea that your tools shouldn't interrupt you. Everything runs locally by default. No accounts, no telemetry, no subscription. Your data stays on your device unless you actively choose to sync it via WebDAV or Dropbox.
It's aimed at developers, freelancers, and anyone who does focused, heads-down work and wants a single place to manage tasks, track time, and review progress without switching between five different tools.
Core task management covers quick-add, subtasks, notes, due dates, repeating tasks with granular schedules, and automatic rollovers for anything you didn't finish.
Board layouts are flexible. Flip between Kanban, Eisenhower matrix, compact list, or a custom view. Projects, tags, and folders let you organize work the way you actually think about it.
Focus and time tracking are built in. One-click timers with keyboard shortcuts, Pomodoro sessions with configurable breaks, and a distraction-free focus mode that hides everything except the task at hand.
Integrations pull work in from outside. GitHub, GitLab, and Jira issues import directly into your boards. Calendar sync via CalDAV gives you a full picture of your day alongside your tasks.
A few things that stand out compared to other workspace organizers:
The app runs on Windows, macOS, Linux, Android, and iOS. It's free, built in the open, and has an active contributor community.
Full-featured project management platform with Gantt charts, agile boards, time tracking, and team collaboration. Self-host or use managed cloud hosting.

OpenProject is a project management suite built for teams that want full control over their data. It supports classic, agile, and hybrid approaches in a single platform, so you're not forced into one methodology. Organizations with strict data requirements, including government agencies, universities, and NGOs, make up a large share of its user base.
The core feature set covers a lot of ground:
Data sovereignty is a genuine differentiator here. You can install it on your own infrastructure and keep everything behind your firewall. The Enterprise on-premises edition adds security features like two-factor authentication, LDAP group sync, and custom branding. For teams that don't want to manage servers, an EU-hosted cloud option is available.
OpenProject is licensed under GNU GPL v3, and development happens publicly. The free Community edition is fully functional and has no time limit. It's a credible Jira alternative for teams leaving Atlassian's self-hosted products, with a migration tool specifically for that transition.
Compared to lighter tools like Kaneo or Operately, OpenProject is heavier and more structured. That's the point. It's built for organizations running multiple concurrent projects that need audit trails, role-based permissions, and reporting across portfolios.
Self-hosted Kanban board for agile teams. Unlimited boards, real-time sync, GDPR-compliant, and available as a free Community Edition or paid Pro.

PLANKA is a self-hosted Kanban board built for teams that want full control over their project data without paying per seat or depending on a third-party cloud. It's a direct alternative to tools like Trello, designed to run on your own infrastructure while still feeling polished and modern.
The free Community Edition covers the core use case well:
For teams that need more, the Pro Edition adds higher scalability, additional professional features, and priority support. Both editions are available as self-hosted installs or through PLANKA's managed cloud hosting if you'd rather skip the infrastructure work.
Compared to other self-hosted options like Wekan or Focalboard, PLANKA puts a stronger emphasis on visual design and ease of use. It doesn't try to be a full project suite with Gantt charts and resource planning. It stays focused on the Kanban workflow, which keeps the interface clean and the learning curve low.
It's been in active development since 2019 and is backed by a growing community that contributes translations, bug reports, and feature ideas. The codebase is transparent and the project has accumulated over 11,000 GitHub stars, a sign that it's earned trust beyond just being a novelty self-host project.
Teams already using tools like Plane or Kaneo for heavier project management might find PLANKA a better fit when the priority is simplicity and speed over feature depth.
