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

Pinglin covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on August 15, 2026. The site is hosted on Vercel. Our crawler found 8 technologies on this site, covering analytics, CSS frameworks, DNS providers, and web fonts. The stack includes Astro, Tailwind CSS, and GoDaddy DNS.

It's also on one of the most common stacks we track, shared by 187 launches.
