ProjectLibre is an open source alternative to Microsoft Project. It is also the new updated version of OpenProj. We were the developers of OpenProj A compliment to Apache OpenOffice and LibreOffice. We have a community site as well at http://www.projectlibre.org It has been downloaded over 500,000 times in 200 countries and was just won InfoWorld "Best of Open Source" award. ProjectLibre is compatible with Microsoft Project 2003, 2007 and 2010 files. You can simply open them on Linux, Mac OS or Windows. ProjectLibre has been rewritten and added key features:

* Compatibility with Microsoft Project 2010
* User Interface improvement
* Printing (does not allow printing)
* Bug fixes

The ProjectLibre team has been the key innovators in project management software. In development of a PPM and cloud/server replacement of Microsoft Project Server. If you download please donate so we can continue https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=PZRJ24PWQE5C8

Simple. Useful. Light.

I'm not sure if it's because it's Java-based, but I'm frustrated by the lack of normal Windows behavior in ProjectLibre. Cntrl-S does not save, Cntrl-X does not cut (it just copies to buffer, the Cntrl-V pastes but leaves original cell as it was), ESC doesn't exit out of dialog boxes, arrow up/down moves the cursor sometimes but not always, highlighting several task rows and choosing to "insert" doesn't insert several rows but instead just adds one (and at unexpected spots), moving/copying a task to an existing summary task does not adjust predecessors for existing tasks in that summary task. Most of this I think is related to it being in Java (would it be that much harder to build for Windows too? I know, easier asked than done...) It's all just a bit too messy to recommend. However, considering that it's free and Project starts at 600 dollars, I'll keep suffering through for at least my current project, since feature-wise it does seem fairly on par with Project.

Very similar to project. Easy to use

It's possible to create a basic project plan with ProjectLibre, but extracting it in a form that other people can read doesn't work nicely - and this is mainly because at default the applications shows every day - so you're plan is normally not shown on one page, but on a whole lot of them. I think I found earlier how to set the timescale to something more normal, but it didn't save my prefference and I can not find it again (and all support-website were down today). Too much trouble to use.

Slow performance speed is a reason to bypass Project Libre 1.59. I've been a user of MS Project for more than ten years, and I've wanted to have a replacement with cost that reduces the barrier to entry for collaboration in project planning and management. Project Libre looks like a good possibility, and there are good reviews from seemingly reliable reviewers. I installed Project Libre 1.59, current in July 2014 as I write this, and verified that my system also contained the most recent Java version, which is recommended in the Project Libre website. Unfortunately I've found Project Libre ver 1.59 is so slow that its operation is very frustrating as projects reach 50 to 100 tasks. Gantt chart view scaling is very limited, choices of time scale in the Gantt chart are very limited, Gantt chart horizontal scrolling is peculiar in that it's both slow and the scrolling increments vary unexpectedly, sometimes it can't scroll to the right-hand end of the chart. Its slow performance speed is the real killer- I'm convinced that the positive reviews didn't involve actual use of Project Libre in a project that reached more than a few tasks in complexity. I REALLY like the apparent intention of the developers to produce a useful tool, but PL is not yet at that point.

I'm not a PM or delivery manager. I build and migrate complex and difficult systems, these work packages take up to 12 months and generally consist of many tasks and milestone, in this context, I find this work is easier to manage if I create detailed team plans. While many reviewers complaints about keyboard mapping and toolbar images and appearance are stylistically accurate, they do somewhat reflect the effect of the Microsoft generation on application design. However, most of the complaints and observations are weak arguments for rejecting a functionally excellent project management tool that is cheap or free. I use ProjectLibre on Windows, Mac and occasionally on Linux. Mostly I just need to keep a list of tasks and link them together so that I can demonstrate some basis for project time span calculations and to keep track of task completion as work progresses. If you're a professional project manager who manages very large and complex projects, the cost of Microsoft project and the overhead of learning to use the tool is small and worth the investment in your time. However, if like me, you need to organize and track work packages with team plans and task tracking then ProjectLibre will be a big asset to your day. I'm confident the project managers and developers of this project know they are making a meaningful contribution to peoples lives with ProjectLibre, but like most people, I bet they appreciate being told they are doing well. So folks, keep doing what you do well, there are lots of users of your project that love it.
