Free tools for planning, scheduling, tracking multiple projects

Hello all,

I would appreciate if you could share your experience/recommendation for free PM tools (excluding Excel-Gantt alternatives) in task-based planning, scheduling and time-based tracking of multiple small projects (e.g. internal projects). Indeed, I am looking for an alternative to MS Project to use in project environments where PM tool is not used for resource management. I am aware of some free tools available but it is important to have feedback from users. I may need to create recursive tasks as well.

Thanks in advance for any feedback.

Regards,

Ismet
