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

OurCalendar ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: no robots.txt and no email security records.

Launched on PeerPush on April 14, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 13 technologies on this site, covering security, analytics, auth, and baas. The stack includes Clerk, Next.js, and React.

It's also running the same core stack as 10,661 other launches and tighter on security headers than most PeerPush launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
