Your Workflow, Simplified

10+ extensions cluttering your toolbar

Frontend Hero replaces color pickers, font identifiers, CSS inspectors, screenshot tools, rulers, and asset downloaders with one extension.

Switching between tools kills your flow

One keyboard shortcut opens Frontend Hero. Switch between 11 tools without leaving the page.

Free extensions break after Chrome updates

Frontend Hero is actively maintained and tested against every Chrome update. No more broken tools on Monday morning.

DevTools is powerful but slow for quick tasks

CSS Scanner shows styles on hover. Color Picker grabs colors in one click. No panels to open, no elements to inspect manually.

Curated Tool Recommendations

CSS Inspection

CSS Scanner (Frontend Hero)11-in-1

Hover over any element to see all its CSS styles instantly, including media queries, pseudo-classes like :hover and :focus, and computed values.

Why you need it: DevTools is powerful but slow for quick inspections. CSS Scanner shows you the exact styles you need without digging through the Elements panel.

Use case: Debugging layout issues, checking what styles a competitor uses, verifying your CSS matches the design spec.

Color Extraction

Color Picker (Frontend Hero)11-in-1

Pick any color from any webpage and copy it as HEX, RGB, HSL, or Tailwind class format.

Why you need it: You need exact color values constantly. The built-in Tailwind output means no manual conversion if you use utility classes.

Use case: Matching brand colors from client sites, sampling colors from design references, building color palettes.

Typography

Font Explorer (Frontend Hero)11-in-1

See all fonts used on a page at once with sizes, weights, line-heights, and font families in one overview.

Why you need it: Instead of hovering text one element at a time, get a full typography audit of any page instantly.

Use case: Identifying font stacks, verifying typography consistency, reverse-engineering design systems.

Documentation

Element Screenshot (Frontend Hero)11-in-1

Click any element to capture it as a clean PNG image with transparent or solid background options.

Why you need it: Full-page screenshots include too much noise. Capture just the component you need for PRs, docs, or bug reports.

Use case: Bug reports, design reviews, component documentation, comparing before/after states.

Generators

CSS Gradient Generator

Create linear, radial, and conic gradients visually with real-time preview and CSS output.

Why you need it: Writing gradient syntax from memory is tedious and error-prone. Visual creation is faster and produces better results.

Use case: Hero section backgrounds, button hover effects, decorative overlays.

CSS Box Shadow Generator

Design multi-layered box shadows with visual controls for offset, blur, spread, and color.

Why you need it: Good shadows use multiple layers. Tweaking values by hand takes forever compared to visual adjustment.

Use case: Card shadows, elevated buttons, depth effects for modals and dropdowns.

Layout Tools

CSS Grid Generator

Build CSS Grid layouts visually with drag-and-drop areas, named template areas, and responsive breakpoints.

Why you need it: Grid syntax is powerful but verbose. Visual building lets you experiment with layouts 10x faster.

Use case: Dashboard layouts, image galleries, complex responsive page structures.

CSS Flexbox Generator

Create Flexbox layouts visually with controls for direction, alignment, wrapping, and gap.

Why you need it: Flexbox has dozens of property combinations. Visual building makes it easy to get the exact layout you want.

Use case: Navigation bars, card rows, centering content, responsive component layouts.

Converters

CSS to Tailwind Converter

Paste any CSS and get the equivalent Tailwind utility classes instantly.

Why you need it: If you work on projects that mix vanilla CSS and Tailwind, this saves hours of manual conversion.

Use case: Migrating legacy CSS to Tailwind, converting designer handoff CSS to utility classes.

Accessibility

Color Contrast Checker

Check WCAG contrast ratios between foreground and background colors with pass/fail results for AA and AAA compliance.

Why you need it: Accessibility is not optional. Catch contrast issues before they become bugs in production.

Use case: Verifying text readability, checking button contrast ratios, auditing existing designs.

Motion Design

CSS Animation Generator

Create CSS @keyframes animations with visual timeline, easing curves, and real-time preview.

Why you need it: Animation timing is hard to get right in code alone. Visual editing with instant preview is the way to go.

Use case: Loading spinners, entrance animations, hover effects, attention-grabbing CTAs.

Measurement

Page Ruler (Frontend Hero)11-in-1

Click and drag to measure any element on the page with pixel-precision guides that snap to element edges.

Why you need it: Pixel-perfect implementation requires precise measurements. Built-in browser tools are clunky for quick measurements.

Use case: Verifying spacing against design specs, checking alignment consistency, measuring gaps between elements.

Frequently Asked Questions

Why should I pay for Frontend Hero when there are free CSS extensions?

Free extensions work individually, but you end up with 6-10 cluttering your browser. Each has different UIs, update schedules, and quality levels. Frontend Hero gives you 11 professional tools in one extension with a consistent interface, active maintenance, and no subscription. At $59 one-time, it costs less than two months of Tailscan.

Do these tools work with all CSS frameworks?

Yes. Frontend Hero's CSS Scanner works with vanilla CSS, Tailwind, Bootstrap, styled-components, CSS Modules, and any other approach. The free generators on this site output standard CSS that works everywhere. The Tailwind-specific tools output utility classes.

Can I use the free tools on this site without buying the extension?

Absolutely. All the generators, converters, calculators, and example pages are 100% free with no signup. The browser extension is a separate product for inspecting live websites.

How many browser extensions do frontend developers typically use?

Most frontend developers have 8-15 browser extensions installed. The problem is that many are single-purpose (one for colors, one for fonts, one for screenshots). Frontend Hero consolidates the most common ones into a single tool, freeing up browser resources and reducing toolbar clutter.

Does Frontend Hero work on localhost and staging environments?

Yes. Frontend Hero works on any website including localhost, staging servers, and production sites. Some free extensions have issues with local development servers, but Frontend Hero is specifically tested for development workflows.
