All-in-one web developer utility for typography, element spacing, rulers, screenshots, CSS scanning, and accessibility checks. Web Dev Kit — CSS Inspector, Accessibility Checker & Frontend Toolbox for Developers & Designers Web Dev Kit is an all-in-one Chrome extension for web developers, UI/UX designers, and accessibility auditors. It combines a CSS and typography inspector, WCAG accessibility checker, screenshot tool, live code editor, component exporter, and responsive viewer into one lightweight sidebar overlay — so you can inspect, measure, edit, and export directly on any live webpage without opening bulky browser DevTools. Stop cluttering your screen with docked developer consoles just to check padding, verify font sizes, test WCAG text spacing, or capture a full-page screenshot. Web Dev Kit gives you visual overlays, live editing, and one-click exports for everyday frontend and accessibility work. WHAT CAN YOU DO WITH WEB DEV KIT? • Inspect computed typography and element spacing on hover • Audit heading hierarchy (h1–h6) for structure and SEO errors • Check canonical URL, Open Graph image, and search index status at a glance • Scan any element's CSS and convert it to Tailwind, Bootstrap 5, SCSS, or MUI sx • Extract design tokens — colors, typography, and spacing — from any live page • Draw alignment rulers across the viewport • Run a WCAG 1.4.12 text spacing reflow check • Sample colors and check WCAG AA/AAA contrast ratios • Audit missing or empty image alt text • Zoom the page up to 400% or use a magnifier lens (2×–6×) for pixel-level inspection • Convert between px, rem, and em, and calculate line-heights • Capture viewport, full-page stitched, or custom-area screenshots • Live-edit CSS and HTML directly on the page • Export any element to React JSX, Vue SFC, or HTML + Tailwind • Simulate dark mode • Preview your page across multiple device sizes side by side • Generate a QR code to open the current page on your phone instantly ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔍 INSPECT — LAYOUT & STYLE ANALYZER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Typography Inspector: Hover any text element to see its computed styling at a glance. Spacing Inspector: Hover to visualize padding and margin, with pixel-accurate distance measurements between elements. Heading Hierarchy: Scans the page and builds an h1–h6 outline, surfacing skipped heading levels and structural issues that hurt accessibility and SEO. SEO: A quick on-page snapshot showing canonical URL, Open Graph image, and whether the page is indexable (index/noindex). CSS Scan: Click any element to extract its live computed styles. Switch the output format between raw CSS, SCSS, Tailwind CSS, Bootstrap 5, or MUI sx — then copy the result or download it as a .css file. Ruler: Drag horizontal and vertical guidelines across the page to check alignment and layout rhythm. Tokens: Extract a page's design tokens — colors, typography scale, and spacing values — in one click, ready to reference in Figma or your Tailwind config. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ♿ ACCESSIBILITY — WCAG AUDITING TOOLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Alt Text: Audits every image on the page and flags missing or empty alt attributes. Color Contrast / Picker: Sample any two colors with an eye-dropper and instantly see the contrast ratio against WCAG AA and AAA thresholds. WCAG 1.4.12 Text Spacing: Runs a reflow check that applies WCAG-required line-height, paragraph, letter-, and word-spacing at a 1280px viewport to reveal overflow or broken layouts. Display — Zoom & Magnifier: Zoom the entire page from 65% up to 400%, or hover with a magnifier lens (2×, 3×, 4×, or 6×) to inspect fine visual detail without leaving the page. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📐 CONVERTER — TYPOGRAPHY MATH ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Typography Converter: Convert pixel values to rem or em against a custom base font size, and calculate unitless line-height from a target pixel value — the two conversions developers reach for a calculator or online tool for, built directly into the sidebar. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛠️ UTILITIES — CAPTURE, EDIT & EXPORT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Screen Capture: Grab a quick viewport screenshot, stitch an entire page into one full-page image, or drag to crop and capture a specific area. Editor: Live-edit CSS and HTML directly on the page and preview changes in real time, or use the Component Exporter to turn any element into React JSX, a Vue Single File Component, or HTML + Tailwind markup — with a Review Changes panel so you can see exactly what's being modified before you copy the code. Dark Mode: Toggle a dark mode simulation to preview how a page looks with inverted/dark theming. Responsive: Preview your page across multiple device sizes — mobile, tablet, laptop, and desktop — side by side on one screen. Quick Share: Generate a QR code for the active tab so you can open and check the page on your phone in seconds. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⌨️ KEYBOARD SHORTCUTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ All shortcuts use Alt+Shift (Option+Shift on Mac) so they never collide with standard OS or browser shortcuts: Alt+Shift+W (Option+Shift+W) — Open the Web Dev Kit panel Alt+Shift+Y (Option+Shift+Y) — Typography Inspector Alt+Shift+S (Option+Shift+S) — Element Spacing Alt+Shift+H (Option+Shift+H) — Heading Hierarchy Alt+Shift+R (Option+Shift+R) — Page Ruler Alt+Shift+A (Option+Shift+A) — Alt Text Auditor Alt+Shift+G (Option+Shift+G) — WCAG Text Spacing Alt+Shift+L (Option+Shift+L) — Dark Mode Toggle Alt+Shift+V (Option+Shift+V) — Responsive Viewer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💎 FREE & PRO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Free (no account needed): ✓ Typography Inspector — font family, size, weight, and line-height on hover ✓ Spacing Inspector — margin, padding, and alignment bounds ✓ Typography Converter — PX ↔ REM/EM and line-height calculations ✓ Heading Outline — H1–H6 hierarchy check ✓ Standard Capture — quick viewport screenshot Pro (one-time lifetime purchase): ✦ Live HTML & CSS Editor — edit markup and write custom CSS directly on the page in real time ✦ Advanced Screen Capture — full-page auto-scrolling screenshots and drag-to-crop area capture ✦ CSS Scan copy & download — copy or download extracted/converted CSS, SCSS, Tailwind, Bootstrap 5, and MUI sx output ✦ WCAG 1.4.12 Text Spacing & Reflow — simulated 1280px viewport spacing validation ✦ Color Contrast Compliance — foreground/background analysis against WCAG AA/AAA ✦ Display Zoom & Magnifier — 65%–400% tab zoom plus a pixel magnifying glass ✦ Custom Context Menus & Hot Keys — configure right-click shortcuts and keyboard bindings Pro is a simple one-time purchase — pay once for lifetime access, including all future Pro features, with no recurring subscription.
