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 15 July 2026; the live site may have changed since.
Greenflash ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Hacker News on July 15, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2023. We've detected 22 technologies on this site, covering analytics, javascript library, security, and ui library. The stack includes Clerk, Next.js, and React.
It's running the same core stack as 10,372 other launches and tighter on security headers than most Hacker News launches.
