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 28 June 2026; the live site may have changed since.
AbacusTool ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on June 28, 2026. The site is hosted on Cloudflare in the United States. We've detected 13 technologies on this site, covering seo, advertising, analytics, and CDN. The stack includes Tailwind CSS, Bing Webmaster, and Cloudflare.
It's running the same core stack as 5,171 other launches.
