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.

Mailviews has the basics covered well, with complete legal pages. What needs work: missing several security headers, no sitemap, and incomplete email security.

Launched on Product Hunt on April 20, 2026. The site is served through Cloudflare, with a domain registered in 2018. Our crawler found 14 technologies on this site, covering analytics, advertising, CDN, and CSS frameworks. The stack includes Tailwind CSS, Vue.js, and Cabin.

It's also running the same core stack as 274 other launches.
