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

SecondBrain ships with the basics, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 weeks before launch. We've detected 9 technologies on this site, covering CDN, DNS providers, business email, and transactional email. The stack includes Cloudflare, Cloudflare DNS, and Fastly.

It's running the same core stack as 1,116 other launches.
