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 24 August 2026; the live site may have changed since.
ByteTools API Directory has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on August 24, 2026. The site is served through Cloudflare, with a domain registered in 2024. Our crawler found 6 technologies on this site, covering CDN, CSS frameworks, frameworks, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 5,352 launches.
