Domestique

open source

Local AI firewall that redacts secrets and PII before prompts leave the machine. Point an agent at it with one environment variable. No CA, no system proxy. Apache-2.0. A personal project built on my own time, not affiliated with Snap.

Security + AI Home Lab

home lab

4 HP EliteDesk mini PCs in a 10-inch rack: an OPNsense firewall, a Proxmox host and bare-metal red and blue nodes on segmented VLANs, with local SLMs for attack and triage.
