The Cobrowse SDK for web is available either using a <script>
tag via CDN, or can be included in your build via NPM.
Add this javascript snippet to the top of the <head>
section of your website.
Please register an account and generate your free License Key at .
This will associate sessions from your website with your Cobrowse.io account.
Cobrowse.io for Web supports all major browsers including Chrome, Firefox, Safari, Opera, Edge, and IE11.
The specific browser versions supported are Chrome 16+, Firefox 11+, Safari 7+, Opera 12.1+, Edge 12+, and IE11.
Please use the following steps to troubleshoot issues on web:
check that all steps of these docs and requirements have been followed
inspect the developer console on the agent and client-side to see any error messages
check the below sections to see if they match the error messages you can see
Certain resources (e.g. CSS) may not be exposed to the public internet (e.g. pre-production environments such as UAT) and so these elements of your webpage will not appear to agents.
Make sure these assets are accessible to our server by making them public.
If you have CSPs on your website then they may block the functionality of Cobrowse.io. When a CSP is blocking Cobrowse.io, then there will be an error in the javascript console stating:
Refused to connect to https://cobrowse.io/... because it violates the document's Content Security Policy.
To allow access to Cobrowse APIs you will need to enable the following in your CSP:
connect src of: connect-src cobrowse.io *.cobrowse.io wss://*.cobrowse.io;
To load the JS SDK and the script tag at the top of this page:
script-src of: script-src js.cobrowse.io 'nonce-2726c7f26c';
You should be able to replace the unsafe-inline with the hash of your snippet if you wish. This will be available in the javascript console.
If the same user has an incognito window (or multiple) running at the same time as their usual browser window, then the incognito windows will be separate devices in the device listing.
Once you have your Javascript snippet and license key set up, navigate to to see your device listed. You can click the "Connect" button to initiate a Cobrowse session!
Note: Cobrowse needs to be able to access your website, so localhost addresses are not recommended for testing. To test on a local development version, we recommend using .
Our Web SDK has an optional "full-device" mode which enables the user to share their entire desktop without any installation. Due to browser limitations, this feature is not available on IE11, or in the mobile browsers such as Mobile Chrome and Mobile Safari. Please see our native and SDKs for on mobile.
check whether the issues persist when using directly
send a description, screenshots, and optionally a video of the above to !
You will see error messages in the developer console relating to https://cobrowse.io/proxy/1/assets/<hex encoded asset>
. You can check which assets are encoded by pasting the hex code into .
Note this is using a nonce source which must also be present on the script tag which adds the Cobrowse SDK to your page. The value 2726c7f26c
represents the random value that should be dynamically generated and unique for each request. Read more about .
If you use the self-hosted version of the web SDK instead of js.cobrowse.io
, e.g. , then you should use that full URL instead, e.g. https://<your instance domain>/sdk-js/CobrowseIO.js
.
