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

SSLCanary ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: no Permissions-Policy.

Launched on Product Hunt on August 18, 2026. The site is hosted on OVH SAS in Canada, with a domain registered 9 weeks before launch. The crawl picked up 6 technologies on this site, covering CSS frameworks, DNS providers, frameworks, and security. The stack includes htmx, Tailwind CSS, and Caddy.

For context, it's one of 30 launches on this exact stack and tighter on security headers than most Product Hunt launches.
