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

InvoiceFast looks production-ready overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 4, 2026. The site is hosted on Cloudflare in the United States, with a domain registered the day of launch. We've detected 9 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Google Funding Choices, Cloudflare, and Cloudflare DNS.
