[[supported-technologies]]
== Supported technologies

The Elastic APM Ruby Agent has built-in support for many frameworks and
libraries. Generally, we want to support all of the most popular libraries. If your favorite
is missing, feel free to request it in an issue, or better yet, create a pull
request.

We follow Ruby's own maintenance policy and officially support all currently
maintained versions per
