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 1 August 2026; the live site may have changed since.
Klosers is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: missing X-Frame-Options and Content-Security-Policy, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on August 1, 2026. The site is hosted on Vercel, with a domain registered 4 weeks before launch. The crawl picked up 8 technologies on this site, covering DNS providers, business email, email marketing, and frameworks. The stack includes Next.js, React, and Brevo.
For context, it's on one of the most common stacks we track, shared by 2,681 launches and more locked down than the typical Product Hunt launch.
