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

fmsg is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 20, 2026. The site is hosted on GitHub Pages and served through Fastly. We've detected 4 technologies on this site, covering CDN, hosting, meta-frameworks, and package cdn. The stack includes Jekyll, cdnjs, and Fastly.

It's a rare Jekyll sighting, just 48 in our data.
