Web based issue tracker?

Question

Project management

You need a task tracker and remote access to it. For some reason, we can’t stick out the office server, so we need a tracker on the Internet.
What you want:
- free
- tickets with statuses
- maintaining versions / releases
- separation of user rights (for projects, for actions)
- time tracking
- the ability to organize subtasks or at least link tickets
- reports on the status of tasks, as a big plus - charts (Gantt or burndown)
It is clear that all the requirements at once are most likely incompatible in free trackers, but I will gladly listen to suggestions. If possible, briefly describe what is present in the proposed tracker. Thank you!

Answer 1

Redmine (http://www.redmine.org/) - the above

Answer 2

mantis (php + mysql) - but you will need to put it somewhere.
look also at teamer.ru - but I’m not sure how fully what you need is now implemented there (if just as tasks, their assignment to performers, communication with projects, that is)

Answer 3

habrahabr.ru/qa/131/

Answer 4

opentodo.ru

Answer 5

depending on what, if under IT projects, then a truck or mantis,
if in general, then a megaplan (domestic) is not bad
