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 8 May 2026; the live site may have changed since.

Simulator86 looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers, no sitemap, and tracking cookies set before any opt-in.

Launched on Hacker News on May 8, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. We've detected 10 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.

It's running the same core stack as 766 other launches.
