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

Siftr looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers.

Launched on Product Hunt on April 2, 2026. The site is hosted on Railway. We've detected 12 technologies on this site, covering analytics, backend framework, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Express, and GoDaddy DNS.

It's on one of the most common stacks we track, shared by 270 launches.
