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 23 July 2026; the live site may have changed since.

Daily1600 is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 23, 2026. The site is hosted on Vercel. We've detected 3 technologies on this site, covering developer tools, hosting, and security. The stack includes HSTS, Vercel, and Vite.

It's running the same core stack as 3,121 other launches.
