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

Instansia ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Product Hunt on June 19, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 8 months before launch. We've detected 12 technologies on this site, covering crm, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 7,957 other launches.
