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 25 August 2026; the live site may have changed since.
Hoppa has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers.
Launched on Product Hunt on August 25, 2026. The site is hosted on Hetzner Online GmbH in Germany. Our crawler found 10 technologies on this site, covering auth, CSS frameworks, DNS providers, and business email. The stack includes Auth.js, Next.js, and React.
It's also on one of the most common stacks we track, shared by 5,475 launches.
