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 25 July 2026; the live site may have changed since.

ACAPELLAS.eu - AI Stem Extractor ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on July 25, 2026. The site is hosted on DATASPACE P.S.A. in Poland. We've detected 14 technologies on this site, covering advertising, consent tooling, servers, and analytics. The stack includes Google Funding Choices, SetupCMP, and Tailwind CSS.

It's running the same core stack as 6,233 other launches.
