HLBuilder

HLBuilder is a web application for designing and planning home laboratory infrastructure. Users drag and drop network components like routers, switches, servers, and storage devices onto a visual canvas, then wire them together to represent physical and logical connections. The tool automatically assigns IP addresses based on network topology, calculates resource requirements across the infrastructure, and generates shopping lists with hardware recommendations and pricing.

Designed for self-hosting enthusiasts, HLBuilder helps plan complex multi-server setups with virtualization support for VMs, containers, and LXCs. It includes a service catalog with pre-configured resource requirements and generates hardware profiles at minimal, recommended, and optimal tiers. According to build evidence, the project uses AI coding tools in development.
