Open-Source AI Racing Harness
Show HN: Open-Source AI Racing Harness
Estimated origin: United States
StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 May 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
Open-Source AI Racing Harness ships with the basics, with complete legal pages and fast page loads. Main gaps: missing several security headers, no robots.txt, and tracking cookies set before any opt-in.
Launched on Hacker News on May 27, 2026. The site is served through Cloudflare, with a domain registered in 2023. We've detected 22 technologies on this site, covering analytics, package cdn, sales intelligence, and security. The stack includes Bito, Calendly, and Cloudflare.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
