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 April 2026; the live site may have changed since.
TaxZap has the basics covered well, with complete legal pages and well-configured email security. Worth fixing first: missing several security headers, no sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 28, 2026. The site is served through Cloudflare, with a domain registered in 1999. Our crawler found 24 technologies on this site, covering advertising, analytics, seo, and CDN. The stack includes 1Password, Amazon SES, and Cloudflare.
