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

PaperPredict ships with the basics, with a thorough launch checklist. Visible gaps: no Permissions-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 3, 2026. The site is hosted on Vercel, with a domain registered 9 months before launch. We've detected 5 technologies on this site, covering analytics, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and HSTS.

It's on one of the most common stacks we track, shared by 1,944 launches and more locked down than the typical Product Hunt launch.
