// what is this

FOSS infrastructure,
catalog + ready to run.

FOSS.Systems is an infrastructure catalog for the infinity ecosystem and beyond. Agents monitor your services, stacks give you reproducible deployments, and patterns document the architecture behind it all.

Agents, stacks, patterns, and templates. All in YAML. All version-controlled.
Discovery
Scan your running system. Get agent recommendations matched to what you run.
Deploy
One command installs any stack with correct config, secrets, and networking.
