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

4 8 15 16 23 42 Don't let it reach zero is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 6, 2026. The site is hosted on Vercel. Our crawler found 8 technologies on this site, covering analytics, DNS providers, email forwarding, and frameworks. The stack includes Next.js, React, and Google Search Console.

It's also running the same core stack as 2,295 other launches.
