Screenshot of Stemify App

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

Stemify App ships with the launch fundamentals in place, with a thorough launch checklist and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 30, 2026. The site is hosted on Netlify, with a domain registered 3 months before launch. We've detected 7 technologies on this site, covering analytics, DNS providers, email forwarding, and web fonts. The stack includes Google Fonts, HSTS, and Microsoft Clarity.

It's running the same core stack as 1,337 other launches and tighter on security headers than most Product Hunt launches.
