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 16 June 2026; the live site may have changed since.

Revast is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 16, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 16 technologies on this site, covering directory, analytics, security, and auth. The stack includes Google Sign-In, Tailwind CSS, and AI Tech Viral.

For context, it's running the same core stack as 281 other launches.
