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 15 June 2026; the live site may have changed since.
Polarsignals looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and broken MTA-STS configuration.
Launched on Hacker News on June 15, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2020. We've detected 15 technologies on this site, covering transactional email, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.
It's on one of the most common stacks we track, shared by 7,516 launches.
