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 June 2026; the live site may have changed since.

Soulver 4 is partway there, with a thorough launch checklist, well-configured email security, and clean crawl signals. What needs work: missing several security headers and incomplete legal pages.

Launched on Product Hunt on June 24, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2019. The crawl picked up 10 technologies on this site, covering seo, analytics, CDN, and DNS providers. The stack includes Apple Business Connect, Apple Domain Verification, and Brevo.

For context, it's running the same core stack as 352 other launches.
