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 August 2026; the live site may have changed since.
Fillo ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.
Launched on Hacker News on August 13, 2026. The site is hosted on Railway, with a domain registered 8 weeks before launch. The crawl picked up 12 technologies on this site, covering javascript library, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 520 other launches and tighter on security headers than most Hacker News launches.
