    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).

    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.

    Redmine has to much focus on software development. It is not a good fit for other kinds of projects.
