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

Letterstory is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 12, 2026. The site is hosted on Vercel, with a domain registered in 2023. Our crawler found 10 technologies on this site, covering analytics, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Google Fonts.

It's also running the same core stack as 2,140 other launches.
