Show HN: Stack Detector – a clean, fast tech stack analyzer (5K+ scans)

I built Stack Detector - a clean, fast tech stack analyser.

Originally, this was just an internal tool. We kept needing quick answers like:

What framework a site is using whether it’s Next.js / Nuxt / custom What analytics, fonts, or infra are behind it

Most existing tools felt costly, noisy, or inconsistent, so I built something simpler, focused on:

fast scans clear output minimal noise

In the last few days, it’s already been used to scan 5K+ websites, which was unexpected.

Would love feedback on accuracy, missing tech, or anything unclear.
