GanttProject

I am a light user, not a project manager.
and I have used this software for personal project.

Here are what I have felt about GanttProject.

Good

• Keyboard friendly : can do many things with keyboard without using mouse.
• Easy to Use : Learing curve is very low in my opinion.
• Clean design : may not beautiful UI but neat and clean.
• Work very smooth and stable
• Open Source

Bad

• Duration, Can not be set a duration less than a day.
  there are so many requests about this feature on the forum,
  but the developer seems not interested in adding "hour" duration.

As a light user using this for only personal project,
This software is very very good.
but if the developer would add hour based duration,
It would be much better than now.

5$ for downloading it is nothing but it is not optional.
FREE?

It does not appear to be dead... only a little slow ;)

Great software, though. You can get it working on a USB key, which is a plus for me.

It can open MS Project files and .CSV files.

I like the tool, It's really easy to use and is very user friendly.

GanttProject is in my opinion the best option I've seen to replace Microsoft Project. I have used it at work and home and find it to be intuitive and a joy to use. Of course there is still room for improvement but there has been steady progress through the years, and the team behind it are to be commended.

If you have a small business or like to make Gantt charts at home or work, this is a great tool. The fact that the software is allowed to be used for free even in commercial settings is a huge plus.

There is nothing wrong with the requests for small donations, this is no different than say LibreOffice asking for money. They have a very decent, stable and usable alternative to the costly MS Project, so give them a donation if possible.

I hope to see more progress coming in the future. Excellent free software. One of my favorites.

No resource leveling. It took me a while to find the online FAQ which says this.

GanttProject is free for any purposes, including commercial use. No license fees, so why it has been registered as Commercial licence?!
Please accept my change about the pricing

Just wanted to mention that the latest version is from Jan 2015, so not dead

There is no contact information on the website and their Mac binary is only PPC meaning that will never work on OS X 10.7

Considering that they have only PPC build I think that probably the last build was many years ago :P
