OpenProject is the best open source Clarizen alternative for project management

Clarizen is one of the oldest project management software applications. In 2021 Clarizen was acquired by Planview and is now a part of Planview AdaptiveWork solution. Let’s take a look at why OpenProject is the best open source Clarizen alternative.

What does OpenProject offer?

OpenProject and Planview AdaptiveWork both offer a wide range of project management features. However, OpenProject is an open source software, which provides full control and transparency over the source code. You are not bound to any specific vendors and can make your own code modifications. OpenProject is the ideal software for organizations that value open source in combination with data privacy and data sovereignty.

Secure Open Source Alternative

Why is OpenProject better than Clarizen for project management

If you are looking for an open source alternative to Planview or Clarizen, OpenProject is the best choice.

We are open source

Clarizen is a proprietary software. Therefore, users run the risk of depending solely on the vendor to make code adjustments and implement feature requests. OpenProject is an open source software and as such it can be the more secure and more cost efficient option. It provides absolute transparency and high flexibility. This article on choosing an open source software further elaborates on the advantages over a proprietary solution.

No compromises in data protection

If you decide to go with the cloud edition, you can be sure that your data is safe. OpenProject has its headquarters in the EU, is GDPR compliant by default and does not process any data outside of the EU. Data collected by Planview could be stored and processed either in the US or in another country where Planview or its subsidiaries or service providers have facilities.

Everything from a single source

While Clarizen offers a lot of features, many functionalities are only available through choosing different software products, which may need to be purchased. OpenProject offers comprehensive project management features set out of one hand and even has a free of charge Community edition with the core functionalities.
