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.

San Francisco Library Events is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 3, 2026. The site is hosted on Vercel, with a domain registered in 2019. Our crawler found 2 technologies on this site, covering hosting and security. The stack includes HSTS and Vercel.

It's also running the same core stack as 2,507 other launches.
