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 18 July 2026; the live site may have changed since.

Predict snow day is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on July 18, 2026. The site is hosted on 20i, with a domain registered 10 months before launch. The crawl picked up 25 technologies on this site, covering social embeds, wordpress plugin, advertising, and package cdn. The stack includes WordPress, 20i, and AddThis.

For context, it's one of only 31 launches we've crawled running 20i.
