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 24 April 2026; the live site may have changed since.

WatchGrid has the basics covered well, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. What needs work: incomplete legal pages and incomplete email security.

Launched on Product Hunt on April 24, 2026. The site is hosted on SAKURA Internet Inc. in Japan. Our crawler found 5 technologies on this site, covering DNS providers, business email, payments, and security. The stack includes HSTS, IIJ DNS, and nginx.

It's also tighter on security headers than most Product Hunt launches.
