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 30 June 2026; the live site may have changed since.

Tinkerfont is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 30, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered in 2014. The crawl picked up 10 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 573 other launches.
