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 12 July 2026; the live site may have changed since.

Coobern — Learn Beyond the Classroom covers some of the launch checklist. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 12, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 4 months before launch. Our crawler found 11 technologies on this site, covering ui library, CDN, cloud, and CSS frameworks. The stack includes Tailwind CSS, Amazon Web Services, and AWS CloudFront.

It's also running the same core stack as 229 other launches.
