What is the NICE DCV Web Client SDK?

NICE DCV is a high-performance remote display protocol. It lets you securely deliver remote desktops and application streaming from any cloud or data center to any device, over varying network conditions. By using NICE DCV with Amazon EC2, you can run graphics-intensive applications remotely on Amazon EC2 instances. You can then stream the results to more modest client machines, which eliminates the need for expensive dedicated workstations.

The NICE DCV Web Client SDK is a JavaScript library that you can use to develop your own NICE DCV web browser client applications. Your end users can use these applications to connect to and interact with a running NICE DCV session.

Using the NICE DCV Web Client SDK as a building block, you can build customized web applications that provide users with instant access to their desktop or applications from anywhere, with a responsive and fluid performance that is almost indistinguishable from a natively installed application.

This guide explains how to use the NICE DCV Web Client SDK to build your custom web browser client applications to interact with NICE DCV sessions within your workflows.


Before you start working with the NICE DCV Web Client SDK, ensure that you're familiar with NICE DCV and NICE DCV sessions. For more information, see the NICE DCV Administrator Guide.

The NICE DCV Web Client SDK supports NICE DCV server version 2020 and later.

A change in the major version, such as from 1.x.x to 2.x.x, indicates that breaking changes that might require code changes and a planned deployment have been introduced. A change in the minor version, such as from 1.1.x to 1.2.x, is backwards compatible, but might include deprecated elements.
