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 14 August 2026; the live site may have changed since.

Oncology Ventures Substack looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and no robots.txt or sitemap.

Launched on Product Hunt on August 14, 2026. The site is served through Cloudflare, with a domain registered in 2010. We've detected 12 technologies on this site, covering security, ui library, backend framework, and CDN. The stack includes Amazon Web Services, Cloudflare, and Cloudflare Bot Management.
