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

Building-an-agent still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 28, 2026. The site is hosted on Techtide in Germany. The crawl picked up 5 technologies on this site, covering analytics, web fonts, media handling, and protocol. The stack includes Asciinema, Caddy, and Google Fonts.
