User reviews

CSS Peeper is praised for simplifying CSS inspection by clearly displaying fonts, colors, and spacing, greatly aiding designers and developers. However, many users express frustration over the shift towards a paid subscription model that restricts key features behind a paywall, accompanied by intrusive UI changes and buggy behavior causing errors. While once a beloved free tool that enhanced workflow efficiency, recent updates have led to negative perceptions, with users seeking alternatives due to diminished free usability and aggressive premium promotion.

Pros

Makes inspecting fonts, colors, and spacing much easier without digging into code.
Accelerates workflow and is very useful for designers and developers.
Clean, simple interface that works smoothly and is helpful for style previewing.
Smart inspection features like typography analysis and color extraction save time.
Previously a highly recommended and effective tool for web development and design tasks.

Cons

Most useful features are locked behind a paywall, limiting functionality in the free version.
Recent updates and UI changes push premium subscriptions aggressively, degrading user experience.
Extension injects unwanted or problematic code causing errors and interfering with web projects.
Free version has become less usable with blurred overlays and broken basic functions.
Users feel the extension has become a cash grab and less reliable compared to prior versions.

Very nice so far! The inspector is much better and handy than the built-in in dev tools.

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.

CSS Peeper requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.
