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 3 July 2026; the live site may have changed since.
Reverse Sales Tax Calculator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 3, 2026. The site is served through Cloudflare, with a domain registered 8 weeks before launch. The crawl picked up 11 technologies on this site, covering analytics, wordpress plugin, CDN, and CMS. The stack includes WordPress, Ahrefs, and Cloudflare.
For context, it's running the same core stack as 1,040 other launches.
