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 August 2026; the live site may have changed since.
Slotmark has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on August 18, 2026. The site is hosted on Vercel, with a domain registered 3 weeks before launch. Our crawler found 8 technologies on this site, covering analytics, DNS providers, business email, and transactional email. The stack includes Expo, Google Search Console, and HSTS.
It's also on a stack we've seen on only 20 launches.
