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

Field Guide to SF Slang still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 21, 2026. The site is hosted on Vercel. The crawl picked up 5 technologies on this site, covering DNS providers, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Dyna-NS.

For context, it's running the same core stack as 3,096 other launches.
