OpenProject

Work packages and Gantt charts

Work is broken into work packages such as tasks, features, phases and milestones, then scheduled on Gantt charts with relations and automatic or manual scheduling.

Agile boards and Scrum

Kanban, team, version and subproject boards, a product backlog, sprint boards, story points and burndown charts are all part of the free Community edition.

Time tracking, costs and budgets

Time is logged on work packages, unit and labor costs are tracked against budgets, and reports break down spent time and costs.

Meetings, wiki and documents

Meeting agendas and minutes link to work packages, and a wiki, forums and collaboratively edited documents hold project information in one place.

Self-hosting or vendor cloud

The Community edition installs on your own Linux servers from DEB or RPM packages, Docker, Kubernetes or Helm charts. Enterprise cloud is hosted by OpenProject in the EU.

Tiered Enterprise add-ons

Paid plans unlock extra features by tier: the team planner on Basic, single sign-on on Professional, and portfolio and resource management on Premium.

Stackfield

Tasks in list, kanban and Gantt views

Tasks carry due dates, assignees, subtasks, custom fields and customizable statuses, and appear as a list, a kanban board with swimlanes, a Gantt chart or a calendar.

Project planning

Gantt timelines with dependencies, milestones, baselines, auto-scheduling and a critical path come with every plan. Portfolios and PERT charts need Premium.

Team chat, discussions and calls

Rooms have a team chat, thread-based discussions and polls. One-to-one audio and video calls are on every plan; group conferences start on Premium.

End-to-end encryption

Content is encrypted in the browser with AES and RSA before it is stored, so the company says it cannot read messages, files or tasks. Servers are in Germany.

Pages, files and whiteboards

Pages act as a wiki, files sit in folders with versioning, and whiteboards on Premium can be edited by several people at once.

Time tracking and reports

Time tracking with estimates and a timer, budget planning for time and money, and filterable reports are included on every plan.
