Bitrix24 is a free task manager with subtasks, checklists and templates. These are all free and unlimited.
You can also create unlimited number of projects (workgroups) for both internal and external Bitrix24 users. Unlike other free task managers that are nothing more
than glorified todo lists, we offer you a number of social collaboration tools that make managing simple tasks and complex projects alike a breeze. Bitrix24 is 100% free for up to 12 users.
With over 30 project management and collaboration tools, Bitrix24 can seem a bit overwhelming at first. If you encounter any problems, please read
Bitrix24 manual in order to better understand how each intranet component works.
