Apache Tomcat (called "Tomcat" for short) is a free and open-source implementation of the Jakarta EE Servlet, Pages, Expression Language, WebSocket, Annotations and Authentication technologies. It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full Jakarta EE application server.

Tomcat is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation, released under the Apache License 2.0 license.
