Dev Toolkit is a powerhouse Chrome Extension built for developers, QA testers, SEO specialists, and web designers. It combines a massive suite of on-page inspection tools with advanced background-crawling capabilities to analyze, debug, and export website data instantly.

🔗 𝑨𝒅𝒗𝒂𝒏𝒄𝒆𝒅 𝑳𝒊𝒏𝒌 & 𝑹𝒆𝒅𝒊𝒓𝒆𝒄𝒕 𝑨𝒖𝒅𝒊𝒕𝒊𝒏𝒈
Deep Link Crawler: Scans every internal and external link on the page, automatically grouping them by domain and page section (Header, Footer, Main Content, Sidebar).

True HTTP Status & Redirect Tracing: Bypasses CORS restrictions using a background engine to fetch the exact HTTP status (200, 404, 403, 500). It traces 301/302 redirects to show you exactly where a link ultimately resolves.

Smart Retry Engine: Automatically attempts connection 3 times for slow or timed-out links to ensure 100% accurate reporting.

Interactive Dashboard & CSV Export: View results in a dedicated, refresh-proof dashboard with dynamic donut charts, smart pagination, and instant filtering. Export pixel-perfect CSVs (UTF-8 format) with a single click.

📝 𝑳𝒊𝒗𝒆 𝑻𝒆𝒙𝒕 & 𝑪𝒐𝒏𝒕𝒆𝒏𝒕 𝑽𝒆𝒓𝒊𝒇𝒊𝒄𝒂𝒕𝒊𝒐𝒏
Expected vs. Actual Engine: Upload a JSON list of expected text or links, and the tool will visually highlight exact matches, partial missing words, and complete mismatches right on the webpage.

CSS Format Checking: Verifies not just the text, but the styling—instantly flagging if a font size, color, weight, or family deviates from your expected design specs.

Hover-Sync Tooltips: Hover over a highlighted mismatch to see a floating tooltip showing exactly what text or link target is broken.

🚀 𝑩𝒖𝒍𝒌 𝑶𝒑𝒆𝒓𝒂𝒕𝒊𝒐𝒏𝒔
Bulk URL Opener: Paste a massive list of URLs and open them instantly in new tabs safely.

Bulk URL Status Checker: Paste hundreds of links to ping their live HTTP status codes in bulk without having to open them.

🔍 𝑶𝒏-𝑷𝒂𝒈𝒆 𝑺𝑬𝑶 & 𝑨𝒄𝒄𝒆𝒔𝒔𝒊𝒃𝒊𝒍𝒊𝒕𝒚
SEO Metadata Checker: Instantly view meta tags, titles, descriptions, and canonicals.

Heading & Alt Tag Overlays: Toggle visual labels directly on the DOM to reveal all H1-H6 tags and Image alt attributes, making accessibility audits a breeze.

🎨 𝑫𝒆𝒔𝒊𝒈𝒏 & 𝑼𝑰 𝑰𝒏𝒔𝒑𝒆𝒄𝒕𝒊𝒐𝒏
Color Audit & Picker: Extract a complete palette of every color used on the current page, or use the eyedropper to grab specific hex codes.

Typography Inspector: Hover over any text to reveal its exact font family, size, weight, and line height.

On-Screen Ruler: Measure pixel-perfect distances, alignments, and padding/margins between DOM elements.

🖼️ 𝑴𝒆𝒅𝒊𝒂 𝑰𝒏𝒔𝒑𝒆𝒄𝒕𝒐𝒓
Right-Click Media Info: Right-click any image or video to instantly view its natural dimensions, file size, render size, source URL, and alt text via a clean modal popup.

⚡ 𝑺𝒆𝒂𝒎𝒍𝒆𝒔𝒔 𝑼𝒔𝒆𝒓 𝑬𝒙𝒑𝒆𝒓𝒊𝒆𝒏𝒄𝒆
Draggable Smart Panel: Access every tool from a sleek, draggable floating menu that injects directly into the page.

Zero-Refresh Data Loss: Reports and audits are saved to local Chrome storage, meaning you never lose your data if you accidentally refresh a tab.
