Simulator86
We just launched our cloud to run your firmware against modern, popular MCUs — from code, not from a browser tab.
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 13 June 2026; the live site may have changed since.
Simulator86 is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no sitemap, and analytics without a consent banner.
Launched on Hacker News on June 13, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 8 months before launch. The crawl picked up 10 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.
For context, it's on one of the most common stacks we track, shared by 239 launches.

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.
