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 15 July 2026; the live site may have changed since.
BounceShift scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 15, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. The crawl picked up 12 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Alpine.js, Tailwind CSS, and Cloudflare.
For context, it's on one of the most common stacks we track, shared by 105 launches.
