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

h5i is partway there, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 17, 2026. The site is hosted on Fastly in the United States, with a domain registered 3 months before launch. The crawl picked up 5 technologies on this site, covering analytics, CDN, DNS providers, and web fonts. The stack includes Cloudflare Web Analytics, Fastly, and GitHub Pages.

For context, it's running the same core stack as 1,143 other launches.
