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

Sentinel still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 18, 2026. The site is hosted on GitHub Pages and served through Fastly. The crawl picked up 4 technologies on this site, covering CDN, web fonts, hosting, and security. The stack includes Fastly, GitHub Pages, and Google Fonts.

For context, it's running the same core stack as 1,757 other launches.
