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 June 2026; the live site may have changed since.

Sessemi looks production-ready overall, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on June 13, 2026. The site is hosted on AS12876 - Scaleway SAS in France, with a domain registered 4 months before launch. We've detected 11 technologies on this site, covering transactional email, analytics, build tooling, and consent tooling. The stack includes Google, Vite, and Amazon SES.

It's on one of the most common stacks we track, shared by 741 launches.
