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 16 June 2026; the live site may have changed since.

Postelix looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on PeerPush on June 16, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 6 weeks before launch. We've detected 13 technologies on this site, covering analytics, advertising, build tooling, and DNS providers. The stack includes Vite, Fastmail, and Google Ads.

It's on one of the most common stacks we track, shared by 647 launches.
