AceProject is one of the oldest online project management software on the market. Originally launched in 2001 as FreeTaskManager, it was rebranded as AceProject in 2003. Ace comes with all the core project management features from expense tracking to Gantt chart and task dependencies. Among AceProject negatives are document management, which is far too basic, and the fact that there is no self-hosted edition available for on-premise deployment. Also, free plan is limited to 5 users/50 tasks, which is not sufficient for work. If you are looking for a free AceProject alternative, Bitrix24 is one of the best options available to you. * Please note that the information may have changed since the publication.
