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 21 August 2026; the live site may have changed since.
OpenSlot scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: tracking cookies set before any opt-in.
Launched on Product Hunt on August 21, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered 4 days before launch. Our crawler found 5 technologies on this site, covering analytics, DNS providers, security, and servers. The stack includes Apache, DigitalOcean DNS, and Google Analytics.
It's also more locked down than the typical Product Hunt launch.
