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 28 August 2026; the live site may have changed since.

Harden ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: no Permissions-Policy and no email security records.

Launched on Hacker News on August 27, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 5 months before launch. The crawl picked up 22 technologies on this site, covering analytics, javascript library, security, and seo. The stack includes Tailwind CSS, Bing Ads, and Cloudflare.

For context, it's running the same core stack as 3,212 other launches and tighter on security headers than most Hacker News launches.
