We have looked for the best open-source software options that offer plenty of workflow management tools, team collaboration and admin features, and free and paid plans. Here’s a quick look at the five platforms we’ll be covering in this roundup, including OpenProject, Redmine, Leantime, MeisterTask and Freedcamp.

The 5 Best Open-Source Project Management Solutions

We’ve shared our five favorite open-source project management tools. Now, it’s time to show you why you should consider each platform if you’re looking to break away from more mainstream options like and Asana or even ClickUp (here’s our ClickUp review) and Wrike (check out our Wrike review). Let’s take a closer look at each platform.

1. OpenProject

OpenProject’s Gantt chart is basic, but it gets the job done.

More details about OpenProject:

  • Pricing: $7.25 per month (one-year plan)
  • Provider website:


  • Strong tool selection
  • Exceptional levels of security
  • Clean & functional interface


  • Tricky to learn
  • Few integrations
  • Strange paid plans

OpenProject is a versatile project management system that’s capable of supporting everything from basic tasks to complex agile methodologies and teams. While the user interface isn’t the prettiest, it’s functional and supports multiple projects. The best part is that this platform can be self-hosted for free or, for a fee, can be hosted on highly secure OpenProject servers.

As mentioned, OpenProject is fantastic for agile project management (with the right plan) thanks to its use of agile boards (kanban boards), easy to use Gantt charts and a robust set of team collaboration tools that include basic chat, wikis and forums, document management, unlimited file uploads (files up to 256MB) and meeting tools. There’s even a native time-tracking tool.

Unfortunately, OpenProject isn’t the easiest project management tool to use, but there are a number of resources, including well-written guides and easy-to-follow videos, that will help you find your way. When it comes to tools for multi-project management, OpenProject is worth a look. You can find out more about the features in our full OpenProject review.

One Overview to Rule Them All

While OpenProject isn’t overloaded with many reports for managers to get stuck in, the software provides a work area where managers can see important information at a glance and analyze project progress.

OpenProject’s overview can be customized to your liking. You can add widgets for the Gantt chart, track milestones and time worked, and view your calendar in one place. It’s an incredibly powerful reporting and task management tool that project managers frequently use. The overview tool lets you see exactly where you and your team stand in seconds.

OpenProject’s overview is a fantastic tool that will give you the lay of the land in seconds.

Regarding plans, the free Community edition allows unlimited users and projects, but removes advanced tools and offers limited support. The Basic $7.25 per user per month plan adds an enterprise add-on (advanced tools) and comes with best-effort community support, OpenProject email support and enterprise-grade security. The $13.50 per user per month Professional plan adds phone support and access to the ticketing system.

The Premium plan, at $19.50 per user per month, adds remote support and faster incident response times. Finally, the scalable Corporate plan adds on-site support, a dedicated engineer and customer support for installed integrations. It’s worth noting that each plan offers incident response times that get faster as you move up through the plans. Overall, OpenProject is a solid platform.

2. Redmine

Redmine looks like software from the ‘80s, but is functional.

More details about Redmine:


  • Free to use
  • Very versatile
  • Great plugin support


  • Dated user interface
  • Ridiculously hard to install
  • Steep learning curve

If you’re looking for powerful, robust open-source project management software, you must look at Redmine. However, know that to get this self-hosted tool working, you need to be tech-savvy or will need an IT department to get it working for you, as the installation is anything but straightforward. You can find out about installation and more in our Redmine review.

On the surface, Redmine looks like a very basic — and dated — project management tool. However, after you spend time with it, you’ll find that the software, which is ideal for software development teams, is powerful and can be used for project management, bug tracking and more. However, be prepared to spend time in the support forums, as the learning curve is steep.

Redmine supports unlimited projects and users, and features a simple Gantt chart, calendar and overview tools. There are wikis for each project you create and support for file sharing, resource management and project news. As for security and privacy, it’s only going to be as good as your servers, so make sure your firewalls are strong.

The Power of Plugins

Redmine is quite basic in terms of features. Still, because the source code is available, anyone can create open-source tools (integrations) for it, and wow, are there a ton of plugins (1,097 at the time of writing) that your entire organization can use.

In the plugin directory, you’ll find support for resource management and communication tools, dashboards, CRM, budgeting and cost management solutions, workflow tools that will help you support numerous projects, support for file storage and more. You can make Redmine anything you want it to be, making it an insanely versatile piece of open-source project management software.

The number of plugins available for Redmine will blow your mind.

If you can overcome the challenging installation process, Redmine will be a fantastic tool for you and your team. You can assign tasks, manage projects, perform bug tracking and complete jobs with ease. The best part is that Redmine is completely free. While Redmine doesn’t make our roundup of the best free project management software, it’s still a great choice.

    3. Leantime

    Leantime’s implementation of the kanban method is commendable.

    More details about Leantime:

    • Pricing: $7 per user per month (first user free)
    • Provider website:


    • Fantastic user interface
    • Easy to pick up & use
    • Lots of tools


    • Limited free plan
    • Not many integrations
    • Simple but confusing plans

    Leantime takes the third spot on our list of open-source project management software thanks to its delightful user interface, which many other visual project planning tools could learn from, and easy-to-use task management tools such as milestones, reports, time tracking and integrations.

    Leantime offers several views, which include kanban boards, lists and Gantt charts. These tools make it easy to set project deadlines, track progress, create subtasks and dependencies, and see completed projects. There are also project dashboards that display vital information. From a security standpoint, you’ll find two-factor authentication with hosted memberships.

    We have discovered that the Leantime team is very receptive to ideas and frequently implements suggestions from the user base into beta versions of the software, and that the support forums are buzzing overall. All the free tools and other features combine to make Leantime easy-to-use project management software.

    Easy-Peasy Team Collaboration

    Team collaboration features steal the Leantime show. Managers and team members can come together to work on project blueprints that can help design a project. Discussions can be had via an idea board (or idea kanban board), and a retrospective board allows teams to discuss what went well and which ideas failed during a project.

    The software also makes chatting and sharing files through task cards easy. Thanks to the bright interface and intuitive menus, the team collaboration tools are as easy to use as the rest of the software. If you’re looking for task management software that encourages open dialogue, Leantime could be the choice for you.

    leantime homepage
    The ideas board is a fine tool that allows teams to chat about ideas that could enhance a project.

    Regarding plans, you can host Leantime on your server for free, or you can choose from free and paid hosted plans. The free Solopreneur plan offers unlimited projects for one user. The One Project Wonder plan allows one project and unlimited users. Costing $7 per user per month (first user free) is The Team plan, which comes with unlimited project support.

    4. MeisterTask

    meistertask kanban
    The workflow tools in MeisterTask are bright, bold and easy to read.

    More details about MeisterTask:


    • Attractive user interface
    • Many tools & dedicated apps
    • Incredibly easy to use


    • Paid plans are a little pricey
    • Cannot be self-hosted

    MeisterTask is open-source software with an incredibly attractive user interface. The views are bold and colorful, with large text that’s easy to read. The biggest downsides are that this software cannot be self-hosted and that the free plan, while suitable for individuals, lacks features. However, MeisterTask is much more than just a pretty face.

    You’ll feel at home if you like kanban boards and Gantt charts. All the plans allow an unlimited number of tasks. The Basic plan only allows three projects, but the paid plans offer unlimited projects. Email support, dedicated apps, time tracking and team collaboration tools come as standard. You can upload files (20MB with the Basic plan and 200MB otherwise) to your projects, too.

    If you like integrations, you’ll be happy knowing that from the Pro plan, you can integrate with Slack, GitHub, Google and many others with Zapier. Depending on your plan, there are also automations, reports, private projects, and advanced admin and security features. Whether you need help tracking simple projects or want to utilize scrum methodology, MeisterTask can do it.

    MeisterTask Can Go Anywhere

    Out of all the open-source software options we have covered in this list, MeisterTask is the only platform to offer native Windows and macOS apps, as well as apps for iPhones, Android devices and even the Apple Watch. MeisterTask didn’t make our list of the best project management for Windows, but it has done a nice job with all of its apps.

    Whether you prefer to work outside a web browser or just want to access your projects and teams from the road, you can. The desktop applications work the same as the web version and have all the same features. The mobile applications offer a little less, but you can still perform essential project management duties with them. It’s nice to have the options.

    Mesitertask homepage
    The iOS, Android and native desktop MeisterTask apps retain the same beautiful interface found in the browser version.

    Regarding pricing, MeisterTask offers three tiers outside of the Basic (free) plan. When paid annually, the Pro plan costs $14.49 per user per month. The Business plan comes in at $26.49 per user per month, which makes it more expensive than Asana (be sure to read our Asana review). There’s an Enterprise option too, but you must contact MeisterTask for pricing.

    Overall, MeisterTask is as wonderful to use for project management as it is to look at. All the core features project managers need can be found in this software, and they’re all easy to use. You’ll be up and running in no time. If you’d like to learn more about the software, check out our full MeisterTask review.

    5. Freedcamp

    freedcamp gantt chart
    The Gantt chart in Freedcamp is slick, colorful and very intuitive.

    More details about Freedcamp:

    • Pricing: $1.49 per month (one-year plan)
    • Provider website:


    • Easy to master
    • Lots of workflow tools
    • Very competitive pricing


    • Cannot be self-hosted
    • Big price jumps betwixt plans
    • Comparatively weak free plan

    Despite being in fifth place, Freedcamp isn’t just here to make up the numbers. The only reason Freedcamp sits in fifth place is that, out of all the open-source PM software we have covered, its free plan is a little sparse. However, overall, Freedcamp is a joy to use and is feature-packed.

    Depending on your plan, Freedcamp gives you access to kanban boards, Gantt charts, tables (spreadsheets) and task lists. There are team collaboration and time-tracking tools, as well as milestone support. You’ll also variably get access to project management tools such as wikis, integrations, invoicing tools and more.

    Unlike many other open-source project management systems, Freedcamp has a user-friendly interface that’s easy to navigate and interact with. Still, should you become stuck, the well-written guides and helpful tutorial videos in the knowledgebase will help you complete your project successfully. Freedcamp also offers a nice suite of security features.

    Integrations Galore

    While many of the more popular native integrations with apps like Google Drive, Dropbox and OneDrive hide behind the Freedcamp paid tiers, the core version of Freedcamp is compatible with the Zapier platform, which allows users to integrate one platform with others and create automations.

    Zapier is compatible with over 5,000 different platforms, so, should you need project management features that aren’t present in the free version of Freedcamp, chances are you can integrate them. This means you’ll be able to easily calculate project costs, manage resource allocation, perform timekeeping and scheduling, and manage projects in general.

    freedcamp zapier
    Thanks to Zapier, you can connect your Freedcamp projects to more than 5,000 different applications.

    Freedcamp’s free plan offers unlimited projects, tasks, storage and users, 10MB uploads and standard customer service. The Pro plan adds task management features and 25MB uploads, and costs $1.49 per user per month when paid annually. The Business plan adds premium support and costs $7.49 per user per month, per annum.

    Finally, the Enterprise plan, with bigger upload limits, costs $16.99 per month when paid annually. Overall, Freedcamp, which comes into its own with its paid plans, is a solid alternative to the likes of Wrike, Asana and ClickUp. Read our full Freedcamp review for all the details.
