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 April 2026; the live site may have changed since.

Api is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 14, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered in 2019. We've detected 3 technologies on this site, covering CDN, hosting, and protocol. The stack includes Cloudflare, HTTP/3, and Render.

It's running the same core stack as 449 other launches.
