Networkmaps review
Free, open-source network diagrams with real-time collaboration and API automation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Networkmaps is a browser-based editor for creating 3D network diagrams and documenting physical connectivity, logical configuration, and routing protocols. It is aimed at teams that need shared network documentation, including small and mid-market organizations. Diagrams can be edited collaboratively in real time, and the project is free and open source. Its focus is documenting topology rather than discovering a live network, so teams seeking automatic inventory or mapping should look elsewhere.
The documentation spans Layer 2 physical connections and Layer 3 logical configuration, with routing information for BGP, OSPF, ISIS, MPLS, and VXLAN. A Layer 3 diagram can be generated from a configured Layer 2 diagram, which gives teams a way to connect physical and logical views. An extensible icon library supports diagram representation. This makes Networkmaps a fit for deliberate, protocol-aware documentation, rather than a narrow tool for drawing simple device layouts.
Networkmaps can run in a hosted environment or on a private server, using a client-server architecture in which the web client connects to a Networkmaps server. An API and library can automate diagram creation and maintenance, which may suit teams with repeatable documentation workflows. The trade-off is that diagrams still need to be supplied or maintained through those workflows; automatic network discovery is not available. Choose Networkmaps if collaborative 3D documentation and API access matter more than live discovery. Choose another mapping product if automatically identifying current devices and connections is central to the job.
