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 10 April 2026; the live site may have changed since.

I made a free alternative to SimpleCitizen (YC S16) ships with the basics, with a thorough launch checklist and fast page loads. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 6, 2026. The site is hosted on Hostinger, with a domain registered 9 months before launch. We've detected 9 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Tailwind CSS, Google Analytics, and Google reCAPTCHA.

It's on one of the most common stacks we track, shared by 570 launches.
