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 6 July 2026; the live site may have changed since.
csvdiff.app looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on July 6, 2026. The site is hosted on Vercel, with a domain registered 9 weeks before launch. We've detected 13 technologies on this site, covering javascript library, ui library, analytics, and CSS frameworks. The stack includes Tailwind CSS, Google Fonts, and Google Search Console.
It's on one of the most common stacks we track, shared by 2,241 launches.
