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 2 August 2026; the live site may have changed since.

CertPrep – AI Certification Coach still has work before launch. Main gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on August 2, 2026. The site is hosted on Google LLC in the United States, with a domain registered 3 months before launch. The crawl picked up 5 technologies on this site, covering APIs, DNS providers, business email, and web fonts. The stack includes Google APIs, Google Fonts, and nginx.
