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 19 August 2026; the live site may have changed since.
CSVUndo scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no email security records.
Launched on Product Hunt on August 19, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 3 technologies on this site, covering CDN, DNS providers, and security. The stack includes Cloudflare, Cloudflare DNS, and HSTS.
It's more locked down than the typical Product Hunt launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
