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

Image Upscaler ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on August 19, 2026. The site is hosted on GMO Internet in Japan, with a domain registered in 2024. We've detected 11 technologies on this site, covering advertising, analytics, DNS providers, and business email. The stack includes ConoHa, Google Ads, and Google AdSense.
