Own this Launch?

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 August 2026; the live site may have changed since.

EdgeLingo ships with the basics, with complete legal pages. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on August 18, 2026. The site is served through Cloudflare, with a domain registered 6 weeks before launch. We've detected 4 technologies on this site, covering CDN, DNS providers, business email, and seo. The stack includes Cloudflare, Cloudflare DNS, and Google Search Console.
