Open-source Workzone alternatives

OpenProject is a web-based project management application for teams and organizations that value transparency, flexibility and control over their data. It covers projects, portfolios, products, tasks, bugs, agile workflows, roadmaps and team collaboration in one platform, and it is built with Ruby and Angular under the GPL-3.0 license.

Key capabilities include agile boards with Kanban and Scrum, project planning and scheduling with Gantt charts, product and release planning, bug tracking, and time tracking with cost reporting and budgeting. Collaboration tools cover wikis, forums, news, and meeting agendas and minutes. Integrations are listed for Nextcloud, XWiki, GitHub and GitLab, among others.

The project presents itself as an open-source alternative to Jira and Asana, along with tools such as MS Project, Monday and YouTrack. It can be self-hosted, which suits organizations with data sovereignty requirements. A free Community Edition is available to download, a 14-day free trial exists, and an Enterprise Edition adds support and add-ons in the cloud or on-premises.

Leantime is an open-source project management system designed for teams where most members are not trained project managers. It joins strategy, planning and execution in one tool and is built with neurodivergent users in mind, including people with ADHD, dyslexia and autism. The README pitches it as simple like Trello yet as capable as Jira.

Task management covers kanban boards, Gantt, table, list and calendar views, unlimited subtasks and dependencies, milestones, sprints and timesheets. Planning and strategy tools include goal and metrics tracking, idea boards, retrospectives, lean and business model canvases, SWOT and risk analysis. There are also wikis and documents, project dashboards, comments on everything, two-factor authentication, LDAP and OIDC, S3 or local file storage, plugins and an API, in over 20 languages.

Leantime is written in PHP, licensed under AGPL-3.0 and installs on your own server, with all of the listed features included in the open-source version. It is positioned as an alternative to Asana, ClickUp, Monday and Notion-style tools, and integrates with Slack, Mattermost and Discord. A hosted option is available at leantime.io.

Redmine is a configurable project management web application that you can host yourself. It is written with the Ruby on Rails framework, is cross-platform and cross-database, and can be configured to fit different ways of working. This repository is a GitHub mirror of the official Subversion repository.

The project site lists the main features: support for multiple projects, flexible role-based access control, an issue tracking system, a Gantt chart and calendar, news, documents and file management, feeds and email notifications, a wiki and forums for each project, and time tracking. Custom fields can be added to issues, time entries, projects and users. Integration covers Subversion, Git, Mercurial, Bazaar and CVS, issues can be created by email, and LDAP authentication, user self-registration and multiple languages and databases are supported.

Redmine is open source software distributed under version 2 of the GNU General Public License. Plugins and themes extend it, and a user's guide, developer's guide, FAQ and online demo are available on the project site.

Worklenz is a project management application intended to help organizations plan work, track progress, and collaborate in one place. Teams can create projects, break them into tasks with due dates and priorities, assign people, and follow status through reports. The code is released under the AGPL-3.0 license.

Beyond task tracking, it offers time tracking on tasks and projects for resource allocation and billing, resource management, project templates, file sharing and comments for collaboration, and reports on project status, team workload, and performance. Analytics and an integration with MinIO for file storage are also part of the repository.

The frontend is built with React and Ant Design, and the backend uses TypeScript, Express.js, and PostgreSQL. You need Node.js 18 or newer and PostgreSQL 15 or newer, or you can use the Docker Compose quick start. It suits agencies and small to mid-sized teams who want a project and time-tracking tool they can run on their own servers.

ZenTao is an all-in-one project management system built around agile development. Its scope goes beyond task boards to cover product management, project management, quality management with bug tracking, documentation, organization and office management, so teams can handle most of their process in a single self-hosted application.

The design supports three methodologies. The Scrum model is meant for fast software iterations, the Waterfall model puts weight on stages and strict process control for well-defined projects, and the Kanban model focuses on visualizing the flow of value. The maintainers present it as the first open-source project management software in China, with a history going back to 2009.

ZenTao is written in PHP and its project topics emphasize that it is self-hosted. The GitHub description promises free upgrades forever for the open-source edition, and the project website offers more detail on its other offerings. It suits software teams that want a single system for backlogs, sprints, test cases and bug reports and that are comfortable running a PHP application on their own server.

GanttProject is a free desktop application for project planning and scheduling. It centers on the Gantt chart, where tasks are arranged in a hierarchy with dependencies, milestones and baselines, and it can also generate a PERT chart for a different view of the same plan.

Other features include a resource load chart, task cost calculation, export to PDF, HTML and PNG, and interoperability with Microsoft Project, Excel and other spreadsheet applications. Projects can be shared with collaborators using WebDAV, or through a commercial collaboration service called GanttProject Cloud. The app is written in Java and Kotlin and runs on desktop operating systems.

GanttProject is free and open-source software under the GNU General Public License v3. Building it requires cloning the repository with its submodules and using Gradle, and a core build without export and import features is available for quick runs. It runs locally on your machine, so no server is needed. It suits project managers, students and small teams who want a no-cost planning tool.

PearProject, also known as Pear, is a lightweight online project and task collaboration system aimed at remote teams and small businesses coordinating work together. It is written in Chinese with a focus on the Chinese-language developer community and requires a separately hosted companion API backend.

The system combines a Vue frontend using Ant Design components with a ThinkPHP backend, using JWT for authentication and WebSocket for real-time features such as live updates between collaborators. A demo instance and demo login credentials are provided so prospective users can try the interface before setting up their own deployment.

PearProject is released under the GPL-3.0 license and requires the separate pearProjectApi repository to function as a complete system. A related Java-based reimplementation by another developer is also referenced as a friend link in the README, suggesting community interest in alternate backend implementations of the same concept.
