Toolkit for designers and developers. Pick colors, grab fonts, check WCAG contrast, simulate color blindness and more.
Everything you need to design and build with confidence.
Designer Toolkit is a focused browser extension that brings essential design and development utilities into one clean, fast workflow. Inspect real websites, extract accurate values, validate accessibility, and turn visual decisions into production-ready output — without leaving the page.
Built for designers, developers, and modern web teams.
🎨 Colors
Pick colors from any website and instantly get clean, usable values.
Save colors to collections, work with multiple formats (HEX, RGB, HSL, OKLCH), generate consistent shade scales, and reuse everything across your design system.
🔤 Fonts
Instantly identify fonts used on any website.
Inspect full typography properties including size, weight, leading, tracking, and color. Copy production-ready values.
♿ Accessibility
Make sure accessibility isn’t an afterthought.
Check WCAG contrast ratios for normal and large text, and simulate color vision deficiencies in real time. Catch accessibility issues early and design experiences that work for everyone.
🧩 Styles
Inspect the full CSS of any element on a website.
Click any element to instantly view its complete set of computed styles, including layout, spacing, typography, colors, and more — all in a clean, readable format without digging through dev tools.
⚙️ Workflow-focused settings
Customize formats, defaults, and behavior to match how you work.
Designer Toolkit adapts to your workflow instead of forcing one on you.
