## Welcome to Apache Tomcat! ### What Is It? The Apache Tomcat® software is an open source implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies. The Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket specifications are developed under the [Java Community Process](https://jcp.org/en/introduction/overview). The Apache Tomcat software is developed in an open and participatory environment and released under the [Apache License version 2](https://www.apache.org/licenses/). The Apache Tomcat project is intended to be a collaboration of the best-of-breed developers from around the world. We invite you to participate in this open development project. To learn more about getting involved, [click here](https://tomcat.apache.org/getinvolved.html) or keep reading. Apache Tomcat software powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations. Some of these users and their stories are listed on the [PoweredBy wiki page](https://wiki.apache.org/tomcat/PoweredBy). Apache Tomcat, Tomcat, Apache, the Apache feather, and the Apache Tomcat project logo are trademarks of the Apache Software Foundation. ### Get It For every major Tomcat version there is one download page containing links to the latest binary and source code downloads, but also links for browsing the download directories and archives: - [Tomcat 10](https://tomcat.apache.org/download-10.cgi) - [Tomcat 9](https://tomcat.apache.org/download-90.cgi) - [Tomcat 8](https://tomcat.apache.org/download-80.cgi) - [Tomcat 7](https://tomcat.apache.org/download-70.cgi) To facilitate choosing the right major Tomcat version one, we have provided a [version overview page](https://tomcat.apache.org/whichversion.html). ### Documentation The documentation available as of the date of this release is included in the docs webapp which ships with tomcat.
