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

Mailguard looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on June 25, 2026. The site is hosted on Cloudflare in the United States. We've detected 5 technologies on this site, covering CDN, directory, protocol, and security. The stack includes Cloudflare, Cloudflare Bot Management, and Google Search Console.
