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

Harness is early-stage. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 13, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered in 2022. We've detected 3 technologies on this site, covering CDN, hosting, and security. The stack includes Fastly, GitHub Pages, and HSTS.

It's on one of the most common stacks we track, shared by 2,267 launches.
