Screenshot of PingBack.sh Free Blind XSS & OOB

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 24 May 2026; the live site may have changed since.

PingBack.sh Free Blind XSS & OOB is early-stage. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on May 24, 2026. The site is hosted on OVH in France. We've detected 4 technologies on this site, covering web fonts, os, security, and servers. The stack includes Apache, Debian, and Google Fonts.

It's tighter on security headers than most Product Hunt launches.
