NixFleet

Declarative NixOS fleet management with staged rollouts and automatic rollback.

NixFleet combines a thin configuration framework (mkHost) with an optional orchestration layer (agent + control plane) for fleet-wide deployments. The framework builds on standard NixOS tooling - it doesn’t replace nixos-rebuild or nixos-anywhere, it adds reproducible multi-host configuration and health-driven deployment safety on top.
