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

Openscreenshot ships with the basics, with well-configured email security, fast page loads, and clean crawl signals. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Hacker News on July 9, 2026. The site is hosted on GitHub Pages and served through Cloudflare, with a domain registered 4 days before launch. We've detected 5 technologies on this site, covering CDN, DNS providers, hosting, and seo. The stack includes Cloudflare, Cloudflare DNS, and Fastly.

It's on one of the most common stacks we track, shared by 1,593 launches.
