Own this Launch?

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 July 2026; the live site may have changed since.

HAR File Viewer is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 13, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered in 2015. The crawl picked up 14 technologies on this site, covering analytics, advertising, CDN, and CSS frameworks. The stack includes Bootstrap, cdnjs, and Fastly.

For context, it's on a stack we've seen on only 21 launches.
