Apache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed under the Java Community Process. Apache Tomcat is developed in an open and participatory environment and released under the Apache License version 2.

The Tomcat projects started at Sun Microsystems as the reference implementation of the Java Servlet and Java Server Pages Specifications. The Java Community Process (JCP) site contains all the details of those specifications.

The Tomcat code base was donated by Sun to the Apache Software Foundation in 1999, and the first Apache release was version 3.0. Since then, multiple volunteers from Sun and numerous other organizations have contributed to the product. There have been multiple major releases and the product has enjoyed considerable industry adoption as well as a healthy and active community. Each major release is aligned to a version of the Servlet Specification.

In 2005, Tomcat became its own top-level Apache project, leaving the Jakarta umbrella and oversight structure to manage itself.
