# ZabFox > Open-source frontend extensions for Zabbix by Alexander Fox (PlaNet Fox). Flagship: Network Topology for Zabbix — an interactive topology map that runs inside the Zabbix 7.0 LTS and 7.4 frontend as a PHP module. No extra server, no build tools, AGPL-3.0. Current version: 5.5.2. Independent project, not affiliated with Zabbix LLC. Key facts: the module directory must be named `network_topology` (the old `_v6` suffix was dropped in 5.0.0). Links between devices are discovered automatically from LLDP/CDP neighbour data (plus UniFi uplink.id). The main module and all five dashboard widgets run on Zabbix 7.0 LTS and 7.4.
