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 17 July 2026; the live site may have changed since.

MaiPDF is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on July 17, 2026. The site is served through Cloudflare, with a domain registered in 2019. The crawl picked up 7 technologies on this site, covering CDN, DNS providers, business email, and transactional email. The stack includes cdnjs, Cloudflare, and Cloudflare DNS.

For context, it's a rare Tencent Cloud Email sighting, just 10 in our data.
