GestióIP vs Open Network Diagram

GestióIP is web-based software for managing IPv4 and IPv6 addresses, with network discovery, IP tracking, search and filtering. Its browser interface needs no additional client software. It discovers networks from layer III routing tables and hosts through ping, DNS, SNMP and DHCP lease processing. DNS features include secure dynamic updates, while lease information can be synchronized from ISC DHCPD, ISC KEA, Microsoft DHCP server and generic lease files. Built-in tools include ping and DNS checks, free-range displays, network split and join operations, a subnet calculator and an IPv6 addressing-plan builder. It imports Excel spreadsheets, exports CSV and generates BIND and tinydns zone files. The free software is licensed under GPLv3. A commercial API adds CRUD and advanced network or IP operations, and an optional Configuration Management Module handles device configurations. It can be installed on-premise or used as a pre-installed cloud service. The listed Configuration Management Module plan for up to 50 devices costs $400 a year; larger device tiers have higher listed annual prices.

Open Network Diagram is a free, self-hosted tool for visualizing and managing home lab and network architecture. It provides network, Hosts & VMs, and rack views for mapping topology and inventory, including subnets, VLANs, virtual machines and rack positions. Connections can record cable type, colour and length. Its IPAM panel reports subnet utilization, detects duplicate addresses and suggests the next free IP. The application keeps JSON as its source of truth; self-hosted changes autosave, writes are persisted atomically, and rolling backups retain the last five files. Deployment is Docker-first, with writable data volumes and Docker Compose support. The runtime exposes GET and PUT operations at /api/network-data, and published Docker images support AMD64 and 64-bit ARM, including Raspberry Pi systems. The project is licensed under GNU GPL v3 and has no runtime dependency on external APIs. It does not include authentication or TLS. The project warns that topology details may expose sensitive infrastructure information and advises restricting access or using an authenticated TLS-terminating reverse proxy.
