Network (nwdiag) templates
Network topology diagrams from a tiny block-style DSL. Declare `network dmz { web1; web2 }` and edges are auto-routed across subnets, with IPs and labels rendered crisply. Renders via Kroki. The fastest way to sketch a corporate network or VPC layout.
Corporate network — 3 subnets
DMZ + internal + database subnets with web servers, DB cluster and a router.
ArchitectureHome lab network
ISP gateway → router → wifi + wired LAN with a NAS and a few clients.
ArchitectureAWS VPC — multi-AZ
Public subnet + private app subnet + private DB subnet across two AZs.
Architecturenwdiag — three-tier web app
DMZ → app → DB segmentation with explicit IPs.
Architecturenwdiag — multi-AZ VPC
Two AZs with public and private subnets each.
Architecturenwdiag — home lab
Router-segmented home lab with IoT VLAN.
Architecturenwdiag — bank network zones
PCI-DSS-style segmentation: edge, app, card-data, backoffice.
Architecturenwdiag — Kubernetes cluster
Control plane vs. worker subnets with ingress + egress.
