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

Lem AI has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 18, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 weeks before launch. Our crawler found 14 technologies on this site, covering analytics, advertising, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 2,716 launches.
