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 10 August 2026; the live site may have changed since.
Prime Agent is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on August 10, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2023. The crawl picked up 28 technologies on this site, covering advertising, analytics, security, and seo. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 12,745 other launches.
