We have compiled the list of open source and freemium tools that offer good features and usability.

Freedcamp

Freedcamp is great for businesses who want to be able to scale with their project management software; the free version will last your company for a long while, and upgrading is cheap, cheap, cheap.

Orange scrum

Orange Scrum is so versatile, serious coding knowledge is required to make the most of this tool.

Ganttproject

GanttProject is another open-source free project scheduling and management tool.

Meister Task

MeisterTask has all the important features: it offers time tracking, issue tracking, and collaboration with both internal and external users. There is no storage limit, so exchanging files is hardly a burden on the system’s capacity.

Asana

Dustin Moskovitz, the co-founder of Facebook,also designed Asana. True to the aesthetic and simplicity of the most popular social network, Asana is an intuitive task-management system that works best for teams seeking real-time interaction.

Trello

Trello uses a method called Kanban, a project management system developed by a former Toyota vice president, Taiichi Ohno, which allows users to move cards—representative of tasks—to create a visual representation of where a project is in development.

Bitrix

Bitrix24 is a project management system entirely free for up to 12 users, with an option to upgrade to more for $99 per month.

Zoho Projects

Zoho projects have a dense list of features and, incredibly, its interface has been compared to the intuitive layout of Facebook. For Waterfall enthusiasts, Zoho Projects has incredible Gantt chart options, allowing users to set complicated tasks and milestones. Zoho Projects also offers timesheets and detailed reporting features (and for those who don’t want to make their own reports, it has 50 pre-made templates to choose from!).

Harvest

This system is great for resource-based project management and reporting. What’s even better is that has an invoicing system, so you can bill your clients with a click of a button. The free version is definitely made for solopreneurs though — it only allows one user, four clients, and two projects. From there, pricing scales up from $12 a month for unlimited clients and projects.

2- plan project management software

From the glut of open-source software, 2-Plan stands out. The system has three symbiotic programs—all free:

• 2-Plan Desktop, a project-management system.
• 2-Plan Team, a web-based project management tool with multiple hosting options.
• Work 2-gether, a Scrum-based task management board for one-team projects.
