User reviews

The Tag Assistant Companion extension is valued by marketers and website owners as a useful tool to debug tag implementations, offering familiarity for those used to GTM preview mode and general utility for tracking evaluation. However, multiple users report significant issues such as unreliable detection on some websites, misleading feedback when tags are blocked due to consent settings, poor documentation, and connection problems after recent updates. These limitations have caused frustration and reduced the extension's effectiveness.

Helpful upgrade from the deprecated Tag Assistant Legacy, familiar for those used to GTM preview mode.

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.

Tag Assistant Companion requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

Tag Assistant Companion is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this extension.
