CSS Peeper Alternatives (1970)
CSS Peeper shows you most styles, but try inspecting a hover effect or a media query with it. You can't. These alternatives can.
CSS Peeper Limitations
No hover/focus state inspection
CSS Peeper can't show you :hover, :focus, or :active styles - you only see the default state.
No media query visibility
Can't see how styles change at different breakpoints. You have to manually resize the window.
No real-time editing
CSS Peeper is read-only. You can't experiment with style changes directly.
Single-purpose tool
If you need fonts, colors, screenshots, or other tools, you'll need additional extensions.
Best CSS Peeper Alternative:
Frontend Hero's CSS Scanner shows what CSS Peeper can't - hover states, focus styles, and media query breakpoints. Plus 10 more developer tools.

Frequently Asked Questions
Hover effects. CSS Peeper literally cannot show you what a button looks like on :hover or :focus. If you build interactive UIs, that's a big gap. Frontend Hero shows all of those hidden states.
Frontend Hero. It shows pseudo-states (:hover, :focus, :active), media query styles at different breakpoints, and lets you edit values live. CSS Peeper is read-only and only shows default state.
CSS Peeper is updated periodically, but its core limitation of not showing pseudo-state styles remains. This is a fundamental design choice, not a bug.
Sure, DevTools shows everything. But it's slower for quick lookups. CSS inspection extensions give you a faster workflow -- click an element, see the styles, copy the code. Frontend Hero is basically that but with DevTools-level detail.
