Own this Launch?

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 15 July 2026; the live site may have changed since.

Spantail is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 15, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. Our crawler found 10 technologies on this site, covering tag management, CDN, DNS providers, and business email. The stack includes Astro, Cloudflare, and Cloudflare DNS.

It's also on one of the most common stacks we track, shared by 252 launches.
