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

Tenjin ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Permissions-Policy and incomplete email security.

Launched on Hacker News on July 2, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 10 weeks before launch. Our crawler found 15 technologies on this site, covering javascript library, security, web3, and analytics. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 9,146 other launches and tighter on security headers than most Hacker News launches.
