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.
Free Mermaid Diagram Editor scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Permissions-Policy and incomplete email security.
Launched on Hacker News on July 7, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 6 weeks before launch. Our crawler found 26 technologies on this site, covering analytics, directory, social embeds, and ui library. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 610 launches and more locked down than the typical Hacker News launch.
