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 17 August 2026; the live site may have changed since.

SSLCanary scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: no Permissions-Policy.

Launched on Hacker News on August 17, 2026. The site is hosted on OVH SAS in Canada, with a domain registered 9 weeks before launch. We've detected 7 technologies on this site, covering CSS frameworks, DNS providers, business email, and frameworks. The stack includes htmx, Tailwind CSS, and Caddy.

It's one of 29 launches on this exact stack and more locked down than the typical Hacker News launch.
