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 27 April 2026; the live site may have changed since.

Subgrapher is early-stage. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 27, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. We've detected 4 technologies on this site, covering CDN, DNS providers, business email, and protocol. The stack includes Cloudflare, Cloudflare DNS, and GoDaddy Email.
