Kernel DevTools 제작자: Peter Joao

Kernel DevTools adds a full suite of developer tools directly into your browser's DevTools panel — everything you need to build, debug, and audit web apps, without switching between tabs or installing multiple extensions.

── TOOLS INCLUDED ──

🌐 Network Inspector
View every request made by the page. Filter by type (Fetch/XHR, JS, CSS, WebSocket), inspect request and response headers, preview response bodies, and check timing — all in one place.

🖥 Console
Full console with timestamps, source file links, and log level filtering. Evaluate JavaScript live with the built-in JS Eval bar. Never lose a log again.

🎭 Mock API Interceptor
Intercept any network request and return a custom response — no backend or proxy needed. Match by prefix, exact URL, or regex. Set status code, response body, and artificial delay. Perfect for testing edge cases and error states.

🔒 Security Suite
Audit any site's HTTP security headers (HSTS, CSP, X-Frame-Options, Referrer-Policy, and more) with instant A–F grading. Spot missing or misconfigured headers at a glance.

📜 Certificate Inspector
View the full TLS certificate for any site — protocol version, key algorithm, validity dates, issuer, and Subject Alternative Names. No more digging through browser certificate dialogs.

💾 Storage Editor
Browse, edit, add, and delete localStorage, sessionStorage, and cookies in a clean table view. Click any key to edit its value inline and save instantly.

🔌 WebSocket Monitor
Capture and inspect every WebSocket message sent and received — direction, payload, size, and timestamp. Essential for debugging real-time apps.

🛡 Tracker Map
See every third-party tracker loaded by the page — analytics, ad networks, fingerprinting scripts — categorised and counted.

🎨 CSS Inspector
Inspect and live-edit computed styles, applied rules, and CSS variables on any element.

⚡ Performance Timeline
Visualise page load performance: resource timing, long tasks, and paint events in a scrollable flame chart.

🌍 DNS Leak Checker
Verify your DNS queries are not leaking outside your VPN or proxy.
