Microsoft Project costs hundreds of dollars per license. That price tag makes a lot of project managers stop and look for something else. ProjectLibre Desktop is the answer most of them find. It gives you Gantt charts, critical path analysis, and resource management for free. It is not a perfect clone of Microsoft Project. But for solo project managers and small teams, it does the job.
This review covers what ProjectLibre Desktop does well, where it falls short, and whether it deserves a place in your toolkit.

What Is ProjectLibre Desktop?
ProjectLibre Desktop is a free, open-source project management app. It was built as a standalone replacement for Microsoft Project. The original developers of OpenProj released it in August 2012. Since then, it has been downloaded over 9 million times across 193 countries.
The app is written in Java. That means it runs on Windows, macOS, and Linux with the same feature set. It supports over 50 languages. More than 1,700 universities use it to teach project scheduling.
ProjectLibre comes in two editions.
| Edition | Target User | Pricing | Key Difference |
|---|---|---|---|
| ProjectLibre Desktop | Individual project managers | Free | Local, single-project management |
| ProjectLibre Cloud | Teams and organizations | From $7/user/month | Real-time collaboration, portfolio management, AI features |
This review focuses on ProjectLibre Desktop. That is the free, open-source edition. But it also explains when you might need the Cloud version instead.
Key Features at a Glance
ProjectLibre Desktop is built for traditional, waterfall-style scheduling. It is not an agile tool. It does not pretend to be one. What it does, it does well.
| Feature | Description |
|---|---|
| Gantt Chart | Full-featured view with task bars, dependencies, milestones, and progress tracking |
| Work Breakdown Structure | Hierarchical task lists with summary tasks and sub-tasks |
| Network Diagram | PERT-style diagrams for task dependencies |
| Critical Path Analysis | Automatically finds tasks that affect your completion date |
| Resource Management | Assign resources and track workloads within a single project |
| Cost Tracking | Set resource rates, track costs, and monitor budgets |
| Baselines | Save and compare baselines to track schedule variance |
| Earned Value Management | Calculate EVM metrics for performance analysis |
| PDF Export | Export project plans for sharing and reporting |
| Language Support | Interface available in over 50 languages |
The app opens in seconds. It uses very little RAM. It runs entirely offline. That last point matters if you work in an air-gapped or restricted network environment.
Installation
Getting ProjectLibre Desktop installed is straightforward. The whole process takes a few minutes. Just pick the right file for your operating system and you are ready to go.
Windows
Download the latest .exe or .msi installer from the official ProjectLibre website or SourceForge. Double-click the file to launch the installer. Accept the CPAL license agreement and follow the prompts. When Windows Defender shows a prompt, select "Trust file" or click "More info" and then "Run anyway" to proceed.
macOS
Download the .dmg disk image from the official site. Open the .dmg and drag the app to your Applications folder. If macOS blocks the installation, go to System Preferences > Security & Privacy and allow the install of ProjectLibre. Note that the latest version (1.9.8) only runs on Apple Silicon Macs. If you have an older Intel-based Mac, download version 1.9.3 from SourceForge instead. You can also install ProjectLibre via Homebrew with the command brew install --cask projectlibre.
Linux
Download the .deb package (for Debian/Ubuntu) or .rpm package (for Fedora/RHEL) from the official site or SourceForge. Install it using your distribution's package manager, or use the standard dpkg -i or rpm -i commands depending on your system.
Java Requirement
ProjectLibre is written in Java, so you need a Java Runtime Environment (JRE) or Java Development Kit (JDK) installed. The minimum is Java 6 or later. If you are on Linux, your distribution's package manager can install Java. On macOS, Homebrew can handle both Java and ProjectLibre with brew install --cask oracle-jdk.
After installation, launch the app and create a new project. You will be prompted to enter a project name, project manager, and optional notes. That is all you need to start building your first Gantt chart.
Microsoft Project Compatibility
This is one of ProjectLibre's best features. You can open existing Microsoft Project files. That means you do not have to rebuild your schedule from scratch.
| File Format | Support Level |
|---|---|
| .mpp (Microsoft Project) | Opens Project 2003, 2007, and 2010 files |
| .xml (Microsoft Project XML) | Import and export supported |
| Primavera P6 | Import supported |
| Native format | ProjectLibre POD format |
There is one big caveat. ProjectLibre can open .mpp files. It cannot save back to .mpp. It saves in its own POD format or XML instead. So if you need to share files with Microsoft Project users, you have to export to XML. That does not always import cleanly into newer versions of Microsoft Project.
Some users also report import problems with complex files. Task IDs can come in wrong. Dates can shift. Custom fields sometimes do not import at all. Simple schedules import fine. Complex or heavily customized ones need manual cleanup.
Pricing and Licensing
This is where ProjectLibre shines.
| Plan | Cost | What You Get |
|---|---|---|
| ProjectLibre Desktop | Free | All desktop features. No subscription. No ads. No trial limits. |
| ProjectLibre Cloud | From $7/user/month | Collaboration, multi-project, AI scheduling, portfolio management |
ProjectLibre Desktop uses the Common Public Attribution License. That is a free and open-source license. There are no hidden costs. There is no premium version of the desktop app. Everything is included.
For comparison, Microsoft Project Professional costs hundreds per license. Microsoft Project Online is also retiring on September 30, 2026. That forces a lot of users to look for cloud alternatives anyway.
If you are an individual project manager on a budget, ProjectLibre Desktop removes the biggest barrier to professional scheduling software. The price.
ProjectLibre Desktop vs. Microsoft Project
| Capability | ProjectLibre Desktop | Microsoft Project |
|---|---|---|
| Gantt Chart | Yes | Yes |
| WBS | Yes | Yes |
| Network Diagram | Yes | Yes |
| Critical Path | Yes | Yes |
| Resource Management | Yes, single-project | Yes, single and multi-project |
| Cost Tracking | Yes | Yes |
| Earned Value | Yes | Yes |
| Baselines | Yes | Yes |
| Multi-User Collaboration | No. Desktop is single-user. ProjectLibre Cloud adds it. | Yes |
| Cloud Sync | No. Desktop is local-only. ProjectLibre Cloud adds it. | Yes |
| Mobile App | No | Yes |
| Agile Support | No | Limited |
| Native .mpp Save | No | Yes |
| Modern UI | Dated | Modern |
| Price | Free | Hundreds per license |
The pattern is clear. ProjectLibre Desktop matches Microsoft Project on core scheduling features. It falls short on collaboration, cloud, and interface polish. For solo project managers, those trade-offs are usually fine. For teams that need real-time collaboration, ProjectLibre Cloud is the upgrade path. It is still much cheaper than Microsoft Project.
The Cloud Option: When Desktop Isn't Enough
ProjectLibre is not just a free desktop tool. The company also sells ProjectLibre Cloud. It is a subscription platform built for teams. It adds the things the desktop edition leaves out on purpose.
Here is what the cloud version adds.
| Feature | ProjectLibre Desktop | ProjectLibre Cloud |
|---|---|---|
| Real-time collaboration | No | Yes. True real-time co-editing. |
| Cloud storage and sync | No. Local files only. | Yes |
| AI-powered project creation | No | Yes |
| Multi-project management | Single project only | Yes |
| Portfolio management | No | Yes |
| Resource leveling | Basic | Project and portfolio level |
| Monte Carlo risk analysis | No | Yes |
| DCMA project audits | No | Yes |
| Shared enterprise resource pools | No | Yes |
| Browser-based access | No. Install required. | Yes |
| Pricing | Free | From $7/user/month |
The cloud platform also imports Microsoft Project files. So you can move existing schedules over without rebuilding them.
Here is the short version for readers.
- Solo project manager? Desktop is free and enough.
- Need collaboration and cloud sync? ProjectLibre Cloud starts at $7/user/month. Still far cheaper than Microsoft Project.
- Need collaboration but want to stay free? Look at OpenProject's community edition instead.
Pros and Cons
Pros
Free, with no compromise on core features. You get Gantt charts, WBS, critical path, resource management, baselines, and earned value. All for zero dollars.
Lightweight and fast. It opens in seconds and uses almost no RAM. Good for older hardware.
Offline-first. Your project data stays on your machine. That matters for air-gapped environments and anyone who cares about data privacy.
Opens Microsoft Project files. You can pick up an existing .mpp schedule and keep working.
Cross-platform. Windows, macOS, and Linux all work the same way.
A clear upgrade path. When you outgrow desktop, ProjectLibre Cloud gives you collaboration and enterprise features without switching vendors.
Cons
Dated interface. Several users say it looks like a Windows 98 program. It works. It just is not pretty.
No real-time collaboration in the free version. The desktop edition is single-user only. Sharing means emailing files back and forth. That creates version-control headaches.
No .mpp save. You can open .mpp files but not save back to them. That causes friction with Microsoft Project users.
Import issues with complex files. Custom fields and newer .mpp formats (2016 and up) may not come through cleanly.
It is a planning tool, not a delivery workspace. Requirements, discussions, approvals, and delivery evidence live somewhere else.
Community support only for the free version. No hotline. Help comes from forums.
What Users Are Saying
ProjectLibre Desktop rates 4.4 out of 5 across 43 verified reviews on Software Advice.
The sub-scores break down like this.
| Category | Rating |
|---|---|
| Ease of use | 4.0 / 5 |
| Customer support | 3.8 / 5 |
| Value for money | 4.6 / 5 |
| Functionality | 4.2 / 5 |
One positive review sums up the appeal. "Overall experience has been satisfying with using ProjectLibre replacing the licensed version of MS Project that costs dollars."
A common criticism sounds like this. "The interface is not that complete compared to MS Project."
Another user put it bluntly. "It works well but the GUI looks like a Win98 program."
The takeaway is consistent. ProjectLibre delivers free, capable scheduling. The rough interface and collaboration limits are real.
How ProjectLibre Compares to Other Alternatives
| Tool | Best For | Pricing | Key Difference |
|---|---|---|---|
| ProjectLibre Desktop | Solo managers, offline planning | Free | Closest feature match to Microsoft Project |
| OpenProject | Teams needing collaboration | Free community edition, paid from $7.25/user | Web-based, real-time collaboration, agile support |
| GanttProject | Simple Gantt charts | Free | Lighter feature set, no resource leveling |
| Microsoft Project | Enterprise teams | Hundreds per license | Full collaboration, cloud, mobile |
| ProjectLibre Cloud | Teams leaving Microsoft Project | From $7/user/month | Adds collaboration and AI to ProjectLibre's core |
Need collaboration and a modern web interface? OpenProject is the stronger free choice.
Need a direct Microsoft Project replacement for solo work? ProjectLibre Desktop is the best free option out there.
Who Should Use ProjectLibre Desktop?
It is a great fit for:
- Individual project managers working one project at a time
- Consultants and freelancers who need pro scheduling without licensing costs
- Project managers in air-gapped or restricted networks
- Organizations leaving Microsoft Project who need a free bridge
- Universities teaching project management basics
- Startups and small businesses with tight software budgets
It is not the right fit for:
- Teams that need real-time collaboration in a free tool
- Organizations that want cloud portfolio management without a subscription
- Agile and Scrum teams. There are no Kanban boards or sprint planning.
- Users who want a polished, modern interface
- Teams working mostly with .mpp files from Project 2016 or later
Final Verdict
Rating: 4.0 / 5
ProjectLibre Desktop is the best free, open-source alternative to Microsoft Project right now. It is not a full replacement. The dated interface, the missing real-time collaboration, and the imperfect .mpp support are real problems. But for solo project managers and small teams on traditional projects, it delivers most of what Microsoft Project does at zero cost.
The tool's biggest strength is focus. It handles Gantt charts, WBS, critical path, and resource management well. It does not try to be a collaboration platform. If you need collaboration, you have a clean upgrade path to ProjectLibre Cloud at $7/user/month. That is still a fraction of what Microsoft Project costs. If you need a free, offline scheduling tool that opens Microsoft Project files and gets the work done, ProjectLibre Desktop is your answer.
Final recommendation: Download it. Try it on your next project. For individual project managers, it is the most practical Microsoft Project alternative on the market. Free or paid.
