Sweepr

Show HN: Sweepr – Daily Minesweeper with a guess-free board generator

sweepr.online · Added June 15, 2026 · Last analysed June 15, 2026 · via Hacker News · 70% unique tagline

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 15 June 2026; the live site may have changed since.

Sweepr ships with the basics. Main gaps: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 15, 2026. The site is hosted on Cloudflare in the United States. We've detected 4 technologies on this site, covering auth, CDN, DNS providers, and protocol. The stack includes Google Sign-In, Cloudflare, and Cloudflare DNS.

It's more locked down than the typical Hacker News launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
