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 17 July 2026; the live site may have changed since.
BulkCert looks production-ready overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: no robots.txt or sitemap and no email security records.
Launched on Product Hunt on July 17, 2026. The site is hosted on Vercel and served through Cloudflare. We've detected 12 technologies on this site, covering security, ui library, auth, and captcha. The stack includes Clerk, Next.js, and React.
It's on one of the most common stacks we track, shared by 10,620 launches and more locked down than the typical Product Hunt launch.
