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 August 2026; the live site may have changed since.

Selleo.com has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Product Hunt on August 27, 2026. The site is hosted on Netlify and served through Cloudflare, with a domain registered in 2006. Our crawler found 21 technologies on this site, covering analytics, security, seo, and advertising. The stack includes Astro, OneTrust, and Tailwind CSS.

It's also one of 46 launches on this exact stack.
