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 30 June 2026; the live site may have changed since.
DueDateHQ scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on June 30, 2026. The site is served through Cloudflare, with a domain registered 10 weeks before launch. Our crawler found 13 technologies on this site, covering security, analytics, CDN, and directory. The stack includes Astro, Amplitude, and Cloudflare.
It's also on one of the most common stacks we track, shared by 186 launches and more locked down than the typical Product Hunt launch.
