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 12 April 2026; the live site may have changed since.
MailBeast.ai is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on PeerPush on April 4, 2026. The site is served through Cloudflare, with a domain registered 11 months before launch. The crawl picked up 19 technologies on this site, covering analytics, business email, email marketing, and transactional email. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 3,887 launches.
