The best open source alternative to Todoist is Macro Tasks. If that doesn't suit you, we've compiled a ranked list of other open source Todoist alternatives to help you find a suitable replacement. Other interesting open source alternatives to Todoist are: Plane, Huly, Super Productivity, and OpenProject.
Todoist alternatives are mainly Project Management Suites but may also be Task Management Tools or Agile Project Management Tools. Browse these if you want a narrower list of alternatives or looking for a specific functionality of Todoist.
Task manager built for engineering teams, combining status tracking, priority management, GitHub integration, and AI agents that can close tasks automatically.

Macro Tasks is a task management tool aimed squarely at engineering teams who want their work tracking, communication, and documentation in one place. It combines the basics you'd expect from any task management app with tighter developer-focused features: GitHub integration for syncing work with code, and AI agents that can act on tasks rather than just surface them.
Instead of bouncing between a project tracker, a chat tool, and a docs platform, Macro puts tasks, channels, email, and docs in one app. While Linear has a honed task management system, an engineering team using Macro has less context-switching and a single source for what's being worked on.
Key capabilities include:
Most task management tools stop at surfacing information or generating summaries with an agent. Macro's are positioned to take action, closing or opening tasks when needed rather than waiting for a human to update the board.
It's a focused product for teams who find general-purpose project tools too disconnected from how engineering work actually flows. Macro is also open source under AGPLv3 in case you want to self-host or audit what's running.
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.
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-hostable agile project management tool with Kanban and Scrum boards, sprint planning, issue tracking, and reporting for teams of any size.

Taiga is an open-source agile project management platform built for cross-functional teams that want structure without complexity. It supports both Kanban and Scrum workflows, and you can switch between them on the same project without losing your work. Teams that don't need training to get started will feel at home immediately.
The Kanban board covers the basics well: WIP limits, swim lanes, custom workflows, EPICS, sub-tasks, and archive functions. Scrum support goes deeper, with full backlog and sprint planning, per-role estimation, a built-in estimation tool called Taiga Seed, burn-down charts at both the project and sprint level, and a sprint task board with swim lanes per user story.
Beyond boards, Taiga includes:
For teams comparing it to Jira or Trello, Taiga sits in a middle ground: more capable than a simple board tool, but far less configuration-heavy than enterprise alternatives like OpenProject.
Self-hosting gives full control over your data, and the codebase is translated into more than 20 languages. The cloud-hosted version is available for teams that prefer not to manage infrastructure. Both paths use the same feature set.
