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 July 2026; the live site may have changed since.
LectureToBook has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on Hacker News on July 19, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 5 months before launch. Our crawler found 15 technologies on this site, covering analytics, CDN, advertising, and cloud. The stack includes Amazon Web Services, AWS CloudFront, and AWS S3.
It's also on one of the most common stacks we track, shared by 355 launches.
