Best Chrome Extensions for UI/UX Designers

UI/UX designers spend most of their day in the browser — researching competitors, extracting design inspiration, testing responsiveness, and collaborating on designs in Figma, Sketch, or other cloud tools. The right Chrome extensions for designers turn the browser into a powerful design inspection and research tool. Here are the essential extensions for 2026.

1. ColorZilla — Pixel-Perfect Color Extraction

ColorZilla adds a professional eyedropper tool to Chrome that lets you sample the exact color of any pixel on any webpage. Click anywhere to get the hex, RGB, and HSL values instantly. It maintains a history of recently picked colors and includes a gradient generator for creating CSS gradients. Essential for extracting brand colors from competitor sites and ensuring your designs use accurate color values.

2. WhatFont — Identify Any Font

WhatFont identifies the font used on any text element on any webpage with a single hover. Click the extension, hover over text, and it shows the font family, size, weight, color, and line height instantly. Click to see the full CSS properties. This is the fastest way to identify a typeface you've seen on a website without manually digging through dev tools or running the page through font detection services.

3. Fonts Ninja

Fonts Ninja goes further than WhatFont — it identifies fonts and shows you where to purchase or license them (Google Fonts, Adobe Fonts, MyFonts), along with preview options and pricing. For designers sourcing typography for client projects, Fonts Ninja shortens the path from "I like that font" to "I have that font licensed and ready to use."

4. Dimensions — Measure Everything on Screen

Dimensions lets you measure the pixel distance between any two elements on a webpage by hovering your mouse. It also shows the dimensions of any element you hover over. This is faster than opening DevTools for quick measurements — useful when you're checking whether a live implementation matches a design spec, or when you want to understand the spacing proportions used on a site you're analyzing.

5. CSS Peeper — Extract CSS Without DevTools

CSS Peeper presents the CSS of any element in a clean, readable panel without requiring you to open the full browser DevTools. Click an element and CSS Peeper shows its typography, colors, spacing, and all other CSS properties in a designer-friendly format. It also extracts all colors and assets (images and icons) used on a page in one click, providing an instant style guide for any website.

6. Window Resizer — Test Responsive Breakpoints

Window Resizer resizes the browser window to any preset or custom dimension with a single click. Test your designs across common mobile (360px, 375px, 390px), tablet (768px, 1024px), and desktop (1280px, 1440px, 1920px) breakpoints without manually dragging the window or using DevTools device emulation. Custom preset sizes can match your specific design system's breakpoints.

7. Loom — Design Feedback and Walkthroughs

Loom is the fastest way to share design feedback and present design decisions. Instead of writing a long email explaining why a layout works, record a 90-second walkthrough showing the design in context. Client presentations, design critiques, and developer handoff notes are all faster and more effective with video than with text. Loom's instant shareable links make distribution effortless.

8. Page Ruler Redux

Page Ruler Redux draws a ruler overlay on any webpage, letting you measure element dimensions and distances in pixels with a visual drag interface. More intuitive than Dimensions for users who prefer a visual ruler over hover-based measurements. It shows x/y coordinates, width, height, and distance from each edge of the viewport.

9. Dribbble New Tab

Dribbble New Tab replaces the default Chrome new tab page with a curated feed of design inspiration from Dribbble. Passive exposure to high-quality design work throughout your day builds visual taste over time. An easy way to keep a connection to the design community without actively visiting Dribbble during work hours.

10. uBlock Origin — Clean Research Sessions

uBlock Origin removes ads from websites, giving you a cleaner view of a competitor's design or a design inspiration site without the visual noise of ads potentially mimicking page elements. Particularly useful when presenting a competitor website during a client call — you don't want a distracting ad appearing mid-presentation.

Conclusion

Every designer's browser toolkit should start with ColorZilla, WhatFont, and CSS Peeper — three tools that make design analysis faster and more accurate. Add Dimensions and Window Resizer for responsive testing, and Loom for communication. Find more design and developer tools in the Unscart extension directory.
