Letterbase
Clean, fast, developer-friendly email. Write. Send. See what worked. No bloat. Free to start.
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 13 April 2026; the live site may have changed since.
Letterbase has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.
Launched on PeerPush on April 13, 2026. The site is hosted on Vercel, with a domain registered 9 weeks before launch. Our crawler found 15 technologies on this site, covering advertising, analytics, auth, and consent tooling. The stack includes Google Funding Choices, Google Sign-In, and Tailwind CSS.
It's also running the same core stack as 2,462 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
