User Reviews

not an API tester at all. Title is __MSG_extensionName__ When it runs it puts up a dialog saying "web dev toolbox" with 3 buttons: - color picker (brings up system color picker) - browser checker (feature coming soon) - code snippets (type your snippet here) None of those will ever test an API, plugin is a demo for some coding exercises, don't waste your time.

Is API Request Tester Safe?

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.

API Request Tester does not require any sensitive permissions.
