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

Lecsium is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on July 7, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 7 months before launch. The crawl picked up 10 technologies on this site, covering CDN, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 609 other launches.
