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 16 August 2026; the live site may have changed since.
Audiobook Speed Calculator scores highly overall, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Main gaps: incomplete legal pages and no email security records.
Launched on Product Hunt on August 16, 2026. The site is hosted on Netlify, with a domain registered 11 months before launch. The crawl picked up 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and 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 429 launches and more locked down than the typical Product Hunt launch.
