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 21 April 2026; the live site may have changed since.

sipsip.ai ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and incomplete email security.

Launched on Product Hunt on April 21, 2026. The site is hosted on Vercel. The crawl picked up 14 technologies on this site, covering analytics, CSS frameworks, directory, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 10,661 other launches and tighter on security headers than most Product Hunt launches.
