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 21 August 2026; the live site may have changed since.
PostJay is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.
Launched on PeerPush on August 21, 2026. The site is served through Cloudflare, with a domain registered 11 weeks before launch. The crawl picked up 14 technologies on this site, covering ui library, analytics, CDN, 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 5,255 launches.
