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 5 July 2026; the live site may have changed since.

ContactAPI covers some of the launch checklist, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on July 5, 2026. The site is hosted on Vercel, with a domain registered the day of launch. Our crawler found 4 technologies on this site, covering DNS providers, hosting, security, and seo. The stack includes Google Search Console, HSTS, and Vercel.

It's also on one of the most common stacks we track, shared by 2,548 launches.
