About Netvorx Tools

Netvorx Tools is the free public toolbox from Netvorx Pro, built for people who run networks for a living.

What this is

Netvorx Tools is a collection of 76 focused utilities across 18 disciplines: address planning, DNS, diagnostics, capacity maths, vendor configuration, AAA, optical and RF engineering. Each one solves a single problem completely, then gets out of the way.

The principles

  • Correctness over convenience. A subnet calculator that quietly mishandles a /31 is worse than no calculator. Edge cases are implemented deliberately and covered by unit tests.
  • Local first. If a calculation can happen in your browser, it does. Configuration you paste in - addresses, shared secrets, keys - never leaves the machine.
  • No dark patterns. No account wall, no rate limit on the free tier, no "unlock with email". The tools are the product.
  • Documented maths. Every page explains the formula, the assumptions and where the result stops being valid.

Who it is for

Network and ISP engineers, NOC and support teams, system administrators, and the students who will replace all of them. If you have ever converted dBm to milliwatts on a phone calculator at the top of a tower, or rebuilt a FreeRADIUS rate-limit string from memory at 2am, this was written for you.

How it is built

The site is statically generated and ships as plain HTML, one stylesheet and a small ES module per tool. There is no framework runtime, no analytics bundle and no third-party script. Pages are typically under 40 KB over the wire, which matters when you are debugging from a phone on an LTE backup link.

Netvorx Pro

Netvorx Pro builds operational software for internet service providers: subscriber AAA, RouterOS automation and network operations tooling. Netvorx Tools is the part we give away.
