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 July 2026; the live site may have changed since.
MechanixCalc ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on July 14, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 8 weeks before launch. The crawl picked up 20 technologies on this site, covering analytics, security, auth, and captcha. The stack includes Clerk, Next.js, and React.
For context, it's running the same core stack as 10,280 other launches and tighter on security headers than most Product Hunt launches.
