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

JerrySniffs looks production-ready overall, with a thorough launch checklist, well-configured email security, and fast page loads. Visible gaps: no Permissions-Policy, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 16, 2026. The site is hosted on Cloudflare in the United States. We've detected 8 technologies on this site, covering CDN, DNS providers, business email, and web fonts. The stack includes Svelte, Caddy, and Cloudflare.

It's one of just 17 launches we've crawled on this exact stack and more locked down than the typical Hacker News launch.
