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

Tennis AI covers some of the launch checklist, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 4, 2026. The site is hosted on Hostinger International Limited in the United Kingdom, with a domain registered in 2025. Our crawler found 9 technologies on this site, covering CSS frameworks, business email, email marketing, and web fonts. The stack includes Tailwind CSS, Brevo, and Google Fonts.

Notably, it's on one of the most common stacks we track, shared by 128 launches.
