About

Dia is an open-source diagramming application that allows users to create a wide range of structured diagrams such as flowcharts, network layouts, and UML designs. Compatible with Windows, Linux, and Mac OS X, Dia offers downloadable shape libraries and scripting options. It is licensed under GPLv2 and includes resources like documentation, bug trackers, and community support.

About

NetworkSketch is browser-based network diagram and documentation software for network engineers, IT teams, MSPs, VARs and telecom professionals. It supports physical and logical topologies built from devices, ports, media types, speeds, VLANs, buildings, racks and subnets, with checks for duplicate IP addresses, out-of-subnet addresses and reused ports. Auto-arrange organizes layouts, while PDF exports combine diagrams with a title block, device inventory, cabling schedule and VLAN information; PNG and CSV exports are also available. Users can start from CDP/LLDP neighbor output, SolarWinds Orion exports, IT Glue or Hudu files, or spreadsheets. Diagram files are edited in a desktop browser and stay on the user's computer; NetworkSketch does not scan or connect to network equipment. Use cases include network planning, site surveys, installation paperwork, as-built records, change documentation, audits and training labs.
