Own this Launch?

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

OpenSpindle scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 31, 2026. The site is hosted on Vercel, with a domain registered 7 months before launch. The crawl picked up 14 technologies on this site, covering analytics, APIs, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Analytics, and Google APIs.

For context, it's on one of the most common stacks we track, shared by 2,710 launches and more locked down than the typical Product Hunt launch.
