Nice and clean WS client extension. I really like it. But for 5 stars I would like to see a lfew more features like being able to extend/drag the 'message text' field (it is pretty small) and some 'clear history' would be nice.

Shame, wanted to use it but can't use custom ports: Unable to open connection: SecurityError: Failed to construct 'WebSocket': The port 6667 is not allowed.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Web Socket Client does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

Web Socket Client has earned a fairly good reputation and likely can be trusted.
