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

App is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on July 27, 2026. The site is hosted on Vercel, with a domain registered 7 months before launch. Our crawler found 6 technologies on this site, covering javascript library, analytics, developer tools, and hosting. The stack includes HSTS, Lit, and Plausible.

It's also running the same core stack as 3,209 other launches.
