GanttProject is free. Software engineering job and hosting are not. We use revenue from ads and paid downloads to make GanttProject better and provide you with fast and reliable web site and download service.
Our ads policy
We always label ads and we always focus user on our own content first. You'll never see ads in the top-left corner,
you'll never see misleading links between text paragraphs.We only have two ad units which is really modest comparing even to such
giants as SourceForge which probably gains much more money from other sources than we do.
We block unfair ads, though. If you find really misleading or fraudulent ad, please take a screenshot, copy URL of a website where it
points to and let us know.
