Built on the Edge
FoxQuery runs entirely on Cloudflare's global edge network. Static pages are served from the nearest edge location for near-instant load times, while our API workers execute diagnostic queries from Cloudflare's infrastructure. This architecture delivers consistently fast results regardless of where you are in the world.
Privacy First
We believe diagnostic tools should not come at the cost of your privacy. FoxQuery does not require accounts, does not track individual users, and does not use cookies for analytics. Our analytics solution, Cloudflare Web Analytics, is privacy-friendly and collects only aggregated, anonymized data. Your queries are processed in real time and are not stored after results are delivered.
