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 3 August 2026; the live site may have changed since.

Litmus 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: incomplete email security.

Launched on Product Hunt on August 3, 2026. The site is hosted on Netlify and served through Cloudflare, with a domain registered in 2021. The crawl picked up 17 technologies on this site, covering analytics, auth, security, and baas. The stack includes Google Identity Platform, Google Sign-In, and Next.js.

For context, it's running the same core stack as 400 other launches and tighter on security headers than most Product Hunt launches.
