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.
FirstSignal has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on August 10, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 7 technologies on this site, covering CDN, DNS providers, business email, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.
It's also on one of the most common stacks we track, shared by 579 launches.
