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 10 April 2026; the live site may have changed since.

PDF Converter — No Upload Required has the basics covered well, with a thorough launch checklist. Worth fixing first: no Content-Security-Policy, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on April 6, 2026. The site is hosted on Vercel and served through Cloudflare. Our crawler found 8 technologies on this site, covering security, auth, CDN, and DNS providers. The stack includes Clerk, Next.js, and React.

It's also running the same core stack as 2,295 other launches and tighter on security headers than most Product Hunt launches.
