Welcome to Llumen
Why Llumen?
Most self-hosted AI interfaces are built for servers, not devices. They're powerful but demand heavy resources and hours of configuration.
Llumen carves out a different space: privacy without the complexity. You get the features you actually need, optimized for modest hardware like Raspberry Pi, old laptops, or minimal VPS-while keeping many features of commercial products.
Private
100% local. Your conversations never leave your device.
Lightweight
~17MB binary, <128MB RAM usage
Zero-config
30-second Docker setup. No config files needed.
