Own this Launch?

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

PassMerge has the basics covered well, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt or sitemap, and analytics without a consent banner.

Launched on Product Hunt on June 7, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 2 days before launch. Our crawler found 8 technologies on this site, covering analytics, security, AI builders, and CDN. The stack includes Cloudflare, Cloudflare Bot Management, and Cloudflare Web Analytics.
