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 24 April 2026; the live site may have changed since.

MailLayer is early-stage. Main gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on April 24, 2026. The site is hosted on GitHub Pages and served through Fastly. We've detected 5 technologies on this site, covering CDN, hosting, icon font, and package cdn. The stack includes Fastly, Font Awesome, and GitHub Pages.

It's on one of the most common stacks we track, shared by 1,758 launches.
