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

Hardin FIlter is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on July 18, 2026. The site is hosted on IONOS, with a domain registered the day of launch. Our crawler found 7 technologies on this site, covering analytics, DNS providers, business email, and hosting. The stack includes Google Analytics, Google Tag Manager, and IONOS.

It's also running the same core stack as 126 other launches.
