The content on this page applies to the new RDC on Sauce platform. If you're looking for instructions on how to run Sauce Connect Proxy on our Legacy RDC platform (TestObject), see Creating a Sauce Connect Tunnel for Legacy Real Device Cloud.
Real Device Cloud on Sauce Labs (RDC on Sauce) offers public and private mobile devices for users looking to expedite automated and live testing for their mobile apps. You can run a high volume of tests across a broad range of real devices without compromising performance, quality, or reliability.
With Sauce Connect Proxy, you’ll have a secure tunnel for testing applications and websites on your local machine (or behind a firewall) against devices and browsers in the Sauce Labs Real Device Cloud.
You must know your account details, including:
- Your Sauce Labs username and access key. In Sauce Labs, click Account and then click User settings.
- The Data Center endpoint associated with your geographic location
We recommend setting all of the values above as environment variables to protect your username and api key from exposure, and also for future convenience. See Using Environment Variables for Authentication Credentials for more information.
If you'd like to restrict Sauce Connect Proxy tunnel deployment to organization admins only, follow the steps in Security Settings to only allow organization admins to start Sauce Connect Proxy tunnels.
In order to begin running tests on public devices using Sauce Connect Proxy or IPSec VPN, your organization admin must enable this option in their settings. Follow the steps in Security Settings to enable Sauce Connect Proxy/VPN for public cloud devices.
Once the setting is enabled, all users across your organization can run live and automated tests on public devices over Sauce Connect Proxy or IPSec VPN. Each time you initiate a test, you'll see a temporary pop-up alert window with a reminder that the utilization of a trusted Sauce Connect Proxy or IPSec VPN connection combined with RDC public real device tests may not be compliant with your organization's network policy.
Testing Mobile Devices Against
Testing with the address
localhost (or the IP address
127.0.0.1) is not supported with iOS or Android real devices in Sauce Connect Proxy.
To work around this, you'll need to edit your hosts file on the machine on which you are running Sauce Connect Proxy. Add an entry for a dummy hostname (such as
localtestsite) and the IP address
127.0.0.1. Requests for
localtestsite in your tests will then be sent through your Sauce Connect Proxy tunnel to
localhost, which is the machine on which you are running Sauce Connect Proxy.
For tips on editing your hosts file, see How To Edit Hosts File In Linux, Windows, or Mac
While rare, there are some test cases that will require you to disable SSL Bumping when using Sauce Connect Proxy in order to avoid certificate issues. For more information, see Sauce Connect Proxy and SSL Certificate Bumping.
Sauce Connect Proxy can have multiple tunnels running simultaneously, as described in High Availability Setup. You can select which tunnel to use in a real device test in the same way as you would any other type of automated test.
- Start Sauce Command Proxy from the command line, providing an
-i (--tunnel-identifer)to start a new tunnel with that identifier (see Sauce Connect Proxy Command Line Quick Reference Guide for more information).
SAUCE_RDC_USERNAME refers to your Sauce Labs username, where:
SAUCE_RDC_ACCESS_KEYrefers to your Sauce Labs access key
SAUCE_DCrefers to the data center API endpoint
TUNNEL_IDrefers to the tunnel identifier
So an example would look like this:
- In your device testing script, specify the tunnel name with
tunnelIdentifierin your desired capabilities, as shown in this Java example:
By default, Sauce Labs will automatically connect you to the main US-West-1 Data Center. For Sauce Connect, you'll need to instead connect to a Sauce Labs REST API Endpoint (US, EU, or Headless) by adding it to your command line and placing an
-x flag before it. For a list of these Sauce Connect-specific endpoints, see Sauce Connect Proxy System and Network Requirements.
In the Sauce Connect Proxy code snippet below, you'll see '-x' followed by the the US Sauce Labs REST API endpoint,
- US Data Center
- EU Data Center

Once you establish a Sauce Connect Proxy tunnel for real device testing, you can also use it for virtual devices (and vice versa) since they'll share the same endpoint.
To ensure you're testing against the correct data center, you'll need to add the correct OnDemand endpoint when you instantiate a MobileDriver in your automated test:

- Java Snippet: Driver Setup for EU Data Center
If your tunnel launch fails with message "Failed to check for existing tunnels," contact Sauce Labs Support and Services to verify that you have Sauce Connect Proxy access enabled on your account.
Sauce Headless is a lightweight infrastructure that allows developers to run early pipeline component tests and sanity checks at scale. It is a container-based architecture for the Virtual Machines that host our headless browsers.
