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 18 June 2026; the live site may have changed since.
CostNest scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.
Launched on Product Hunt on June 18, 2026. The site is hosted on Amazon.com in the United States. We've detected 14 technologies on this site, covering advertising, analytics, APIs, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's on one of the most common stacks we track, shared by 7,880 launches and more locked down than the typical Product Hunt launch.
