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.

Send Letters Online UK looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on PeerPush on July 3, 2026. The site is hosted on Google LLC in the United States, with a domain registered 7 weeks before launch. We've detected 22 technologies on this site, covering analytics, ui library, advertising, and AI builders. The stack includes Clerk, Next.js, and Rspack.

It's one of just 5 launches we've crawled on this exact stack.
