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.

Combines project management, team chat, virtual office, and collaborative docs into a single platform. A self-hostable alternative to Linear, Jira, Slack, and Notion.

Huly brings together the tools that most teams spread across four or five separate apps. Project management, real-time chat, collaborative documents, and a virtual office all live in one workspace. It's built for product and engineering teams who are tired of context-switching between a task tracker, a Slack alternative, and a Notion alternative.
The project management side covers what you'd expect from a modern tracker:
The virtual office is a built-in audio and video conferencing environment. Teams can create custom rooms for departments or recurring meetings, and invite guests without sending them to a separate tool. No third-party conferencing app required.
Documents in Huly support rich text, images, attachments, and code blocks. Live real-time collaboration means multiple people can edit simultaneously. You can tag teammates, link directly to issues, and assign action items from within a document, which keeps planning and execution connected. Version history tracks every edit.
The collaborative workspace also includes a unified inbox and instant notifications, so updates from tasks, documents, and chats surface in one place rather than scattered across tools.
Huly is self-hostable, which matters for teams with data residency requirements or those who simply want control over their infrastructure.
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.
