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 23 August 2026; the live site may have changed since.

linecast ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Hacker News on August 23, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered in 2022. Our crawler found 18 technologies on this site, covering analytics, javascript library, email marketing, and CDN. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's also running the same core stack as 333 other launches.
