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

Sifio is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 15, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 9 weeks before launch. The crawl picked up 10 technologies on this site, covering seo, analytics, CDN, and DNS providers. The stack includes Docusaurus, Bing Webmaster, and Brevo.

For context, it's one of only 50 launches we've crawled running Docusaurus.
