HTTP & Security Headers Auditor

bgfc97/http-security-headers-audit

Audit any list of URLs: status, final redirect, HTTPS, server, security headers (HSTS, CSP, X-Frame-Options...), a security score, page title and CMS/generator. No key, no proxy.

Bulk-check URLs for HTTP security headers. Grades sites A+ through F based on HSTS, CSP, XFO, XCTO, Referrer-Policy, and Permissions-Policy presence.

Audit a public website's HTTP security response headers in one API call. Returns a letter grade, numeric score, per-header analysis, and actionable recommendations. Built for security teams, devops, and site migration QA.

Audit HTTP security response headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/COEP/CORP) for any URL. Returns a 0-100 grade, letter rating, and a prioritized fix list with exact header values to add. Single polite GET per URL, no crawling.

Audit which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Googlebot, and 30+ more) your site allows or blocks, validate your llms.txt, and score AI-citability — with an exact prioritized fix list. Non-scraper, reads public well-known files.

Bulk-check TLS certificates for any HTTPS hosts: days-to-expiry, expiry alerts, and issuer/SAN/fingerprint change detection. Pure protocol, no scraping.

Convert, resize, compress, and strip metadata from many images at once — to WebP, AVIF, JPEG, or PNG. Use as a serverless image optimization API for bulk image conversion, compression, and resizing. Pure compute on image URLs you supply; no scraping.
