Pros & Cons
Bitrix24
Pros

- Task views include list, Kanban, Gantt, calendar and Scrum, plus task templates with subtasks and checklists.
- A full CRM, telephony, chat and video calls are built in, so sales and delivery teams can work on one platform.
- Collabs give clients and freelancers controlled access to project spaces.
Cons

- Some users report slow loading, especially with large or complex workflows.
- Support gets mixed reviews, and some customers say issues can take days to resolve.
- Task time tracking, task automation and analytics require Professional or higher.

OpenProject
Pros
- The free self-hosted Community edition is GPLv3 open source and shares one codebase with the paid editions.
