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 11 August 2026; the live site may have changed since.
LeetRivals scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Permissions-Policy, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on August 11, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 13 technologies on this site, covering analytics, javascript library, APIs, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 12,865 launches and more locked down than the typical Product Hunt launch.
