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 19 August 2026; the live site may have changed since.

Paperswift has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on August 19, 2026. The site is hosted on Vercel. Our crawler found 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 13,532 launches.

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.
