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 10 August 2026; the live site may have changed since.

Ercc looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on August 10, 2026. The site is hosted on Tencent Building in Singapore. We've detected 11 technologies on this site, covering directory, analytics, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, 22.cn, and 51.la.

It's running the same core stack as 6,830 other launches.
