HTTP Analyzer Pro автор Sitego

HTTP Analyzer Pro is a powerful developer tool for inspecting HTTP requests, response headers, redirects, server IP addresses, geolocation, and performance metrics — all in one clean interface.
Key Features

Two Analysis Modes
• On Demand — click Analyze to reload the page and capture all data. No background activity, zero resource usage when idle.
• Always On — automatically monitors every page load. The extension icon shows a color-coded HTTP status badge: green (2xx), orange (3xx), red (4xx), purple (5xx).

Headers Inspector
— View all request and response headers organized into logical groups: Main, Cache, Security, CORS, Cookies. Copy individual headers or all at once with one click.

Redirect Chain
— See the complete redirect path with HTTP status codes, server IPs, and Location headers at each step — invaluable for debugging redirect loops and tracking URL changes.

Geo IP — Three Independent Sources
— Click the country flag card to open the dedicated Geo tab. Data is provided from three independent sources — DB-IP, ip-api, and MaxMind — displayed side by side so you can compare results. The ip-api source also shows Proxy, Hosting, and Mobile flags for each IP.

Security & Performance Audit
— Instantly check HTTPS status, HTTP protocol version (HTTP/1.1, HTTP/2, HTTP/3 / QUIC), HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and more. Performance metrics include TTFB, DOM ready time, full load time, and transfer size.

Analyze Any URL
— Enter any URL in the address bar and press the arrow button — the extension opens it in a background tab, captures all data, and closes it automatically. No need to navigate away from your current page.

TLS Details (Chrome / Chromium only)
— View cipher suite, TLS protocol version, and certificate information via Chrome DevTools Protocol.

Multi-language Interface
— Available in English, Russian, Spanish, Arabic, Chinese, and French.

Privacy
— All header analysis is performed locally in your browser. The only external request is to the geolocation service to look up server IP addresses — no personal data, browsing history, or page content is ever transmitted.

Perfect for:
• Web developers and backend engineers debugging HTTP issues
• DevOps and sysadmins monitoring server responses
• Security researchers analyzing headers and TLS configuration
• SEO specialists tracking redirects and cache headers
