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

InstaCourse has the basics covered well, with complete legal pages, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers.

Launched on Product Hunt on June 30, 2026. The site is hosted on Microsoft Corporation in the United States, with a domain registered in 2025. Our crawler found 10 technologies on this site, covering javascript library, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare DNS, and Google Fonts.

It's also running the same core stack as 5,266 other launches.
