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

CacheCatch covers some of the launch checklist, with a thorough launch checklist. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 8, 2026. The site is hosted on Vercel and served through Cloudflare. Our crawler found 10 technologies on this site, covering analytics, CDN, frameworks, and hosting. The stack includes Next.js, React, and Cloudflare.

It's also on one of the most common stacks we track, shared by 2,084 launches.
