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

Letting an LLM write robot programs still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Hacker News on April 7, 2026. The site is hosted on HETZNER-AS in Germany, with a domain registered 1 week before launch. The crawl picked up 3 technologies on this site, covering DNS providers, protocol, and servers. The stack includes Caddy, HTTP/3, and Porkbun DNS.
