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

CROSSBOW | Secure UDP File Transfer is partway there, with clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 15, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 5 technologies on this site, covering CDN, web fonts, security, and seo. The stack includes Cloudflare, Cloudflare Bot Management, and Google Fonts.
