About Gatecko Tools

Gatecko Tools is a lightweight network diagnostics website built on Cloudflare Workers. It provides tools for checking IP address, DNS records, HTTP headers and basic web security headers.

Why Cloudflare Workers?

Running at the Cloudflare edge means your requests are handled by a data center near you — typically within milliseconds. There are no origin servers to maintain, no cold-start delays, and the infrastructure scales automatically.
