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 July 2026; the live site may have changed since.

Opbox still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 3, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 5 technologies on this site, covering DNS providers, web fonts, hosting, and security. The stack includes Cloudflare DNS, Google Fonts, and HSTS.

For context, it's on one of the most common stacks we track, shared by 2,508 launches.
