I might have found the timeline generator tool that I have been looking for – it’s clean, simple and user-friendly. You can easily generate timelines for your small projects and export them in PDF, CSV or embed them in your websites (as seen below).
Free version allows you to add up to 5 tasks per project (which is quite less), pro version costs $29 that allows you to add unlimited number of tasks per project. The fee is a one-time fee which gives you lifetime pro membership.
