    ProjectLibre has been downloaded over 4,700,000 times for a reason. It is clearly the best alternative to MS Project. Gantt chart, Network Diagram, WBS, RBS... earned value costing etc. It is a clone of MS Project

    It is very similar to Microsoft Project, but free. The GUI is a bit old styled, but the resulting project graphics are good and uses the same style as Microsoft Project.

    It is great because it gives you gant charts free. thats the only thing it does though and though it;s great some of the others do offer more features however this is the best one that is free to use

    Standalone WIndows app that is very easily installed (no server needed). Quite complete Gantt features including FS, FF, SS and SF dependencies and the possibility to change task colors. It's rather basic as project management software (no "to do" list per week, no comments on tasks, no display filters, no collaboration...), and a bit old-school looking, but as a free Gantt solution it's one of the best (together with ProjectLibre).

    This is a cloud app. MS Project is a desktop app.

    I disagree with the poster who gave this a thumbs down. Not everyone looking for an alternative is looking for like-to-like. For instance if one has one's own webspace and a chromebook or skips between devices then a self hosted alternative with a free starting point would be quite attractive.
