Mailbrew
Create beautiful, automated newsletters with content from the sites and apps you love.
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 July 2026; the live site may have changed since.
Mailbrew ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.
Launched on PeerPush on July 12, 2026. The site is hosted on Vercel, with a domain registered in 2016. The crawl picked up 12 technologies on this site, covering analytics, DNS providers, business email, and email marketing. The stack includes Next.js, React, and Amazon SES.
For context, it's running the same core stack as 2,140 other launches.
