SimTelemetry

Free AI sim racing telemetry analysis tool. Record, upload, and analyze your driving data.

Added July 25, 2026 · Last analysed July 25, 2026 · via Hacker News · 60% unique tagline

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 25 July 2026; the live site may have changed since.

SimTelemetry is partway there, with complete legal pages and fast page loads. Visible gaps: missing several security headers, no robots.txt, and no email security records.

Launched on Hacker News on July 25, 2026. The site is hosted on Vercel. The crawl picked up 11 technologies on this site, covering analytics, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 11,400 launches.
