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 18 June 2026; the live site may have changed since.

Flyfish is partway there, with complete legal pages and well-configured email security. What needs work: missing several security headers and no robots.txt or sitemap.

Launched on Product Hunt on June 18, 2026. The site is hosted on Microsoft Corporation in the United States, with a domain registered in 2018. The crawl picked up 11 technologies on this site, covering business email, CSS frameworks, DNS providers, and email marketing. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 2,715 other launches.
