## About DevWeb

In VuGen, you can use the DevWeb protocol to create DevWeb scripts. Recording is supported for the latest web technologies (HTTP, HTTPS, HTTP/2, WebSocket, gRPC). HTTP/3 is supported for replay.

All DevWeb scripts can be executed with any of the OpenText Performance Engineering family products.

You can also create DevWeb scripts using the OpenText Performance Engineering for Developers standalone application, which gives you the option to run your scripts using the command line or an IDE configuration. You can download OpenText Performance Engineering for Developers from the ADM Marketplace. For more information, see the Help Center.

## Get started with DevWeb

When you install VuGen, the installation automatically create the environment variable %DEVWEB_DATA_PATH%. This points to the path for the DevWeb configuration files in VuGen (defined as <installdir>\DevWeb).

If you are just starting out with DevWeb, you might find it helpful to view the tutorial videos available in the Video gallery and in the Help Center.

You can also experiment using the example DevWeb scripts available in the \<DevWeb_data_path>\examples directory.

Note: To use an example script, import it into VuGen. See Import DevWeb scripts.
