• JSON-LD structured data & Schema.org microdata (itemtype)
• Core Web Vitals – LCP, FID/INP, CLS measured live on the page
• Page speed metrics via Navigation Timing & Resource Timing API
• Well-known files: robots.txt, sitemap.xml, security.txt, ads.txt,
humans.txt, llms.txt – fetched and validated automatically
• Tracker detection – Google Analytics, GTM, Meta Pixel, and more

Export your audit results as JSON or Markdown for client reports.
View SEO audit history for up to 50 recent pages.
────────────────────────────────────────
🎨 COLOR PICKER & EYEDROPPER
────────────────────────────────────────
Pick any color from any webpage with pixel-perfect accuracy.
• Uses the native EyeDropper API for precision sampling
• Fallback canvas-based picker works on every page including images
and SVG files

────────────────────────────────────────
📸 SCREENSHOTS & ANNOTATIONS

• Full-viewport screenshot with one click
• Rectangle crop tool – select exactly the area you need
• Copy screenshot to clipboard or download as PNG

• Color-coded pins for visual organization
• Up to 200 annotations stored locally, organized by page URL
────────────────────────────────────────
🛠️ DEVELOPER TOOLBAR & DEBUG PANEL
────────────────────────────────────────
A draggable, always-available on-page toolbar built for devs.
• Drag and drop to any position on the screen – remembers placement
• Customize which tools appear in the toolbar
• Quick access to SEO audit, color picker, screenshots, annotations,
and page information from any page
• Debug panel: inspect cookies (name, value, domain, path, flags),
localStorage and sessionStorage of the visited page
• Performance overlay with live Core Web Vitals indicators
• Context menu integration – right-click any page to run SEO audit
or toggle the toolbar
────────────────────────────────────────
🤖 BUILT FOR AI-ASSISTED DEVELOPMENT
────────────────────────────────────────
DevAudit fits naturally into modern AI coding workflows –
whether you use Cursor, Claude Code, GitHub Copilot, or
any other AI assistant.
• Screenshot a broken UI, copy it to clipboard, paste directly
into your AI chat as visual context
• Annotate the exact element that needs fixing – pin a Bug note
on the page, copy the annotation text, send it as a prompt
• Run an SEO audit, export as Markdown, paste the report into
your AI assistant to generate fixes or content improvements
• Pick a color from a live design, copy the HEX value, use it
instantly in a prompt ("change the button to #E84C3D")
• Capture a reference screenshot of a competitor's layout,
annotate what you want to replicate, feed it to your AI
• Copy structured audit data (JSON export) as context for
automated fixes – no manual copy-pasting from DevTools
Stop switching between browser, DevTools, screenshot apps,
and AI chats. DevAudit keeps everything one click away so
your AI prompts are faster, richer, and more precise.
────────────────────────────────────────
🔒 PRIVACY FIRST – 100% LOCAL
────────────────────────────────────────
DevAudit is built with a strict privacy-first architecture:
• Everything runs on your device – no cloud, no servers
• No analytics, no telemetry, no tracking (no Google Analytics,
Sentry, Mixpanel, or similar)
• Your notes, screenshots, color picks, and audit results are stored
only in chrome.storage.local – never transmitted anywhere
• No account required, no sign-up, no email
• All libraries (React, Lucide icons) are bundled locally –
no external CDN requests at runtime
• During SEO audit: limited HEAD requests to check broken links
and fetch robots.txt / sitemap.xml – no personal data included
• Full data export/import as local JSON backup – you own your data
