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 24 June 2026; the live site may have changed since.
PreCall is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. Our crawler found 5 technologies on this site, covering DNS providers, business email, hosting, and security. The stack includes HSTS, Namecheap DNS, and PrivateEmail.
Notably, it's running the same core stack as 2,263 other launches.
