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 16 June 2026; the live site may have changed since.

Sebu Ai Auto Thumbnail is early-stage. What needs work: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on June 16, 2026. The site is hosted on TURKTICARET.NET YAZILIM HIZMETLERI SAN. ve TIC. A.S. in Türkiye, with a domain registered 3 months before launch. We've detected 11 technologies on this site, covering build tooling, chat widgets, DNS providers, and business email. The stack includes React, Vite, and Google Fonts.

It's on a stack we've seen on only 4 launches.
