Added July 31, 2026 · Last analysed July 31, 2026 · via Hacker News

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 31 July 2026; the live site may have changed since.

Uml is partway there, with complete legal pages and fast page loads. Main gaps: missing several security headers, no sitemap, and no email security records.

Launched on Hacker News on July 31, 2026. The site is served through Cloudflare. The crawl picked up 3 technologies on this site, covering CDN, package cdn, and protocol. The stack includes Cloudflare, HTTP/3, and unpkg.
