About

About Networkzeug / PacketGauge

Focused tools for understanding how networks, DNS, web services, routing, and mail systems connect.

What we build

Networkzeug and PacketGauge share one application and one security model. The tools provide bounded diagnostics with validation, SSRF protection, rate limiting, timeouts, response limits, and controlled output.

Browser-local tools stay in the browser where practical. Server-side operations use the same API enforcement path as the public API.

How to use it

Choose a tool, read its scope and limits, use an authorized target, and treat the result as evidence for further investigation rather than as a final authority.
