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 21 April 2026; the live site may have changed since.
TaxSimple scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 21, 2026. The site is hosted on Vercel. The crawl picked up 12 technologies on this site, covering analytics, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 10,662 launches and more locked down than the typical Product Hunt launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
