Apache Tomcat: sovereignty score and 8 European alternatives

Apache Tomcat is an open-source implementation of several Jakarta EE specifications and is described as a servlet container. It supports Jakarta Servlet, Jakarta Pages (JSP), Jakarta Expression Language, Jakarta WebSocket, Jakarta Annotations and Jakarta Authentication, among others. Developers use Tomcat to run Java web applications. Tomcat 10 and later implement Jakarta EE, while Tomcat 9 and earlier implement Java EE; moving between them usually requires code changes because the package namespace changed from javax.* to jakarta.*. Tomcat is software that you install and operate yourself.

Tomcat is developed by the Apache Software Foundation, a US non-profit corporation headquartered in Delaware, under the Apache License 2.0. Because the software is open source and self-hosted, you decide where the application server runs and where your data resides. A European organisation can therefore run Tomcat on its own servers or with a European hosting provider, without depending on a cloud service operated by the foundation.

Why digital sovereignty matters with Apache Tomcat

Apache Tomcat is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Data is hosted exclusively in the EU, so Apache Tomcat scores best on data residency.

Apache Tomcat is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Apache Tomcat together with your other vendors and gives a total score, a heatmap and the main risk drivers.
