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 29 June 2026; the live site may have changed since.
ProperSend scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on June 29, 2026. The site is served through Cloudflare, with a domain registered in 2021. Our crawler found 16 technologies on this site, covering analytics, javascript library, CDN, and chat widgets. The stack includes Tailwind CSS, Brevo, and Cloudflare.
It's also on one of the most common stacks we track, shared by 5,216 launches.
