Project planning with Gantt chart

A key requirement for many projects is the ability to plan and track a project’s progress through a Gantt chart.


Trello does not support progress visualization using Gantt charts.

There are however several third-party plugins which add Gantt charts to Trello.


OpenProject enables progress visualization using Gantt charts both for single projects as well as multi-hierarchy projects.

Gantt charts are automatically filled with existing work packages and can be filtered / configured to meet specific needs.

Cost and time tracking

An essential feature for any larger project is the ability to track the time as well as the cost spent on a project.


Trello does currently not offer a functionality to log time or costs.

There are however some integrations with third-party tools.


Time tracking can be enabled for each project separately within OpenProject.

Additionally, OpenProject allows users to track costs - both personnel costs as well as unit costs.

Furthermore, budgets can be created within projects to compare planned and realized costs.

A sophisticated permission model allows users to restrict the data that users can see. This includes for example whether they can only see and edit their own tracked time or those of all users within a project.

Additional criteria

Aside from the differences in functionality there are also additional criteria which should be considered.

Data security is one important aspect when choosing a project management tool. Therefore both OpenProject and Trello offer regular data backups.

When software is open source it provides maximum flexibility and independence: Users can make their own adjustments.

Thus, OpenProject is open source. Trello on the other hand is proprietary.
