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 25 June 2026; the live site may have changed since.
Postproxy - Engagement API ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing Content-Security-Policy and Strict-Transport-Security and tracking cookies set before any opt-in.
Launched on Product Hunt on June 25, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 months before launch. The crawl picked up 9 technologies on this site, covering analytics, CDN, chat widgets, and DNS providers. The stack includes Astro, Cloudflare, and Cloudflare DNS.
For context, it's running the same core stack as 156 other launches and tighter on security headers than most Product Hunt launches.
