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

Mailto.Bot scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing Content-Security-Policy and Strict-Transport-Security and tracking cookies set before any opt-in.

Launched on Product Hunt on April 20, 2026. The site is hosted on Google LLC in the United States, with a domain registered 5 days before launch. Our crawler found 8 technologies on this site, covering analytics, CSS frameworks, DNS providers, and transactional email. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 3,885 launches and more locked down than the typical Product Hunt launch.
