In the world of web design and front-end development, inspecting styles and assets from live websites is a daily necessity.

That’s where CSS Peeper comes in.
CSS Peeper is a Chrome extension that simplifies the process of inspecting and extracting design elements from any website. With its intuitive interface and powerful features, it’s become a favorite among designers, developers, and creative teams. And now, thanks to its lifetime deal on AppSumo, you can get permanent access to this tool for a one-time price.
This review explores CSS Peeper’s features, benefits, pricing, and whether the lifetime deal is truly worth it for professionals looking to streamline their design workflow.
What Is CSS Peeper?
CSS Peeper is a Chrome extension built specifically for designers and frontend developers who want to inspect websites without diving deep into the browser’s DevTools. Unlike standard Inspect Element features that bombard users with lines of code, CSS Peeper presents a clean, organized, and designer-friendly interface to reveal CSS properties, color palettes, typography, and spacing in seconds.
The tool is not only fast but also visually intuitive, making it a favorite for creative professionals working with modern web interfaces. It allows users to:
- Instantly inspect any website element
- Explore color palettes and semantic groups
- Access typography details and hierarchy
- Download assets like images, SVGs, and icons
- Preview layout spacing, padding, and borders
- Switch between light and dark modes
Created by Dawid Młynarz in 2016, CSS Peeper was born out of frustration with the clunky nature of browser dev tools. Today, it boasts a user base of over 500,000 designers worldwide.

Key Features of CSS Peeper
Visual CSS Inspector
CSS Peeper allows you to inspect any element on a webpage simply by clicking on it. Instead of opening Developer Tools and scrolling through nested styles, the extension shows clean CSS summaries that are easy to read and understand.
You can view:
- Fonts and font sizes
- Colors and background gradients
- Spacing, padding, and margins
- Border radius and shadows
- Positioning and layout details
All this in an organized, minimalist UI — perfect for non-coders or hybrid designer-developers.
Color Palette Extraction
One of CSS Peeper’s most loved features is the automatic extraction of a site’s color palette. With just a click, it scans the entire page and generates all the colors used — primary, secondary, backgrounds, buttons, and more.
You can copy HEX or RGB values or export the full color palette for use in your design tools like Figma or Adobe XD.
Asset Download
Need a logo, image, or icon from a website? CSS Peeper lets you quickly download all images and assets from a page — including SVGs and high-resolution images. This is a major time-saver for UI/UX designers doing competitive analysis or redesigns.
The best part? You don’t need to inspect the source or manually find the image URLs.
Typography Analysis
CSS Peeper displays all the typography styles in one place, including:
- Font families
- Sizes
- Weights
- Line heights
- Text colors
This is extremely helpful for designers seeking typographic consistency or aiming to replicate existing web design patterns.
Layout Preview
Get a visual breakdown of layout elements like margin, padding, box sizes, and containers. This helps designers and developers understand spacing and alignment strategies used in real-world websites.

Why the CSS Peeper Lifetime Deal is a Steal?
Unlike many modern SaaS tools that demand recurring subscriptions, CSS Peeper offers a lifetime license — meaning you pay once and use it forever. This is a rare find, especially for a tool this polished and professional.
One-Time Payment, Unlimited Use
Whether you’re working on one website or a hundred, CSS Peeper costs the same — a small, one-time fee (often less than the cost of one monthly design software subscription).
Speed Up Your Workflow
Designers using tools like Figma, Sketch, or Adobe XD can benefit greatly from analyzing live websites in seconds and translating styles to design systems — without jumping into raw code.
