Getting Started with Relay Classroom


Welcome to Relay Classroom, we developed this tool to help you facilitate and manage your students’ Internet activity during class. With Relay Classroom, you can monitor web traffic, respond to the students who need help, and so much more.

Relay Classroom is easy to set up, it only takes four simple steps.

Note: If you were a Classroom Orchestrator user, refer to this guide Removing Classroom Orchestrator Agents before getting started with Relay Classroom.


  • Must be running within a Chrome browser or OS. Microsoft Edge does not support Relay Classroom.
  • Note: Relay Classroom supports Chrome’s two previous versions from its current stable version. For example, if Chrome’s current stable version is 67, Relay Classroom supports all versions 65 or greater.
  • Must Enable Screenshots in the Google Admin Console.

The following outbound ports must be open on your network:

  • TCP/UDP-443 to communicate to the cloud servers
  • TCP/UDP-3478 to share and broadcast screens
  • TCP-5349 to share and broadcast screens

The following domains/hosts should be allowed on your network:


Step 1- Add Classes

The first step in setting up Relay Classroom is importing your users (teachers and students), your groups, and your memberships. You can do this using your student information system (SIS) at Launch > Admin Tools > SIS. You will need to log into Launch with your Relay Classroom credentials.

If you need some help setting up your SIS integration, take a look at our community site documentation on SIS integration basics.

Setting up your user and group information in Google Classroom is the simplest way to import your organization’s information. Take a look at our community site documentation on Google Classroom integration for more information.

Note: Classroom supports a maximum of 40 students per class.

Step 2 (Chrome)- Deploy the Classroom Extension for Chrome

Deploy the Classroom Extension for Chrome to all of your students. If your teachers want to use the Share Screen feature, they also need the Classroom Extension deployed to them.

Deploy the Google Chrome Extension

Open the Google Admin console and navigate to Device Management.

Click Chrome Management from the left-side menu (Device Settings), then click User Settings.

Choose your organization from the left menu (Organizations), then scroll down to Apps and Extensions > Force-installed Apps and Extensions. Click on Manage force-installed apps. Click on Specify a Custom App.

Enter your organization-specific App ID and URL in the ID and URL fields. Then click Add.

Note: Refer to the Relay (Step 3) or Classroom (Step 2) Getting Started page and click Details for the App ID and URL. You can also find your organization-specific App ID and URL on Relay’s Settings > Chrome Extension page.

Once added, the App ID is listed in the Total to force install list. Click Save to push the extension.

Ensure Extensions are Allowed

Our web-filtering services (for Chrome) are deployed to devices via a Chrome Extension. By default, Extensions should be allowed, but if you have issues pushing the extension to a device, ensure that this setting is enabled.

To verify that extensions are allowed from the Google Admin console, navigate to the list of Allowed Types of Apps and Extensions (Device Management > Chrome > User settings > Apps and Extensions > Allowed types of Apps and Extensions) and ensure that the box next to Extension is marked. Click Save to apply this setting.

Disallow Incognito Mode

Chrome’s Incognito Mode allows users to browse the Internet privately. While user activity isn’t hidden in Incognito Mode, it’s best to disallow this feature when setting up your web-filtering service.

To disallow Incognito Mode from the Google Admin console, navigate to Incognito Mode (Device Management > Chrome > User settings > Security > Incognito Mode) and select Disallow Incognito Mode from the drop-menu. Click Save to apply this setting. Click Save to apply this setting.

Never Allow Developer Tools

Chrome’s built-in developer tools give users access to the browser’s (and other web applications) internal code. It’s best to never allow users access to the browser’s built-in developer tools.

To never allow access to Chrome’s built-in developer tools, from the Google Admin console, navigate to Development Tools (Device Management > Chrome > User settings > User Experience > Developer Tools) and select Never allow use of built-in developer tools from the drop-menu. Click Save to apply this setting.

Note: After configuring these changes in the Google Admin Console, be sure to click the Save button.

Step 2 (Mac)- Deploy the Classroom for Mac OS Agent

Follow these steps to install the Rely Classroom agent for MacOS devices:

  1. Obtain and download the ClassroomSA.dmg file by emailing and providing your Customer ID.
  2. Working from the target workstation as an Administrator, make a local copy of your Smart Agent .dmg file accessible…
  3. Open the ClassroomSA.dmg and complete the installation. Move the installer file to the trash when complete.
Tip: Need to deploy the MacOS Classroom Agent to multiple machines? Refer to our documentation, Deploy the MacOS Agents with Third Party MDM for help.

Step 3- View Real-Time Browsing Activity

Before going live, make sure that your devices are communicating with Relay Classroom:

  1. Log into Relay Classroom as a group owner.
  2. Set the schedule for your group so that you can test it out.
  3. Log into a Chromebook or Chrome browser as a student that is in the group.
  4. Verify that the student’s browsing activity and screen monitoring are working as expected.

Step 4- Announce that Relay Classroom is Available

Relay Classroom provides teachers with numerous valuable tools to monitor students’ web activity and keep them on track. After you’ve got Relay Classroom set up, you’ll want to make sure your teachers have access and can use these tools.

We have all the resources your teachers will need to get up to speed with Relay Classroom in no time. Send them to our Intro to Relay Classroom document or Relay Classroom for Teachers course , and let us take it from there!
