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

Signfy scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy and no email security records.

Launched on Product Hunt on April 23, 2026. The site is hosted on Vercel. Our crawler found 5 technologies on this site, covering DNS providers, web fonts, hosting, and security. The stack includes Google Fonts, Google Search Console, and HSTS.

It's also on one of the most common stacks we track, shared by 2,956 launches and more locked down than the typical Product Hunt launch.
