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

OpenDevUtils is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on July 11, 2026. The site is hosted on Vercel, with a domain registered 3 days before launch. The crawl picked up 9 technologies on this site, covering ui library, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare DNS, and Google Search Console.

For context, it's running the same core stack as 2,347 other launches.
