Open Source Todoist Alternatives

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.

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:

• Team Planner consolidates individual tasks into a shared calendar so you can see workload across the whole team at a glance.
• Time-blocking lets you turn tasks into structured time slots in your personal planner.
• GitHub sync works both ways. Huly connects to GitHub Issues and GitHub Projects, syncing changes instantly, supporting multiple repositories, and migrating milestones between them.
• Advanced filtering makes it practical to search and slice project data across large backlogs.

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.

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:

• Board view for Kanban-style task tracking with drag-and-drop cards
• Table view for a spreadsheet-like overview of all items
• Gallery view for visual, image-forward layouts
• Calendar view for deadline and date-based planning

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.

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:

• Work logging and reports generate timesheets and summaries instantly, which is useful for freelancers billing by the hour or consultants tracking project time.
• Procrastination helper uses CBT-based prompts to help you actually start a task, not just look at it.
• Plugin system lets you extend the app with custom automation and quick commands.
• Keyboard-first design means most actions have shortcuts, so you rarely need to reach for the mouse.
• No vendor lock-in: export everything as JSON or CSV at any time.

The app runs on Windows, macOS, Linux, Android, and iOS. It's free, built in the open, and has an active contributor community.
