labcoat

labcoat [options] [flakepath_]

labcoat is a terminal user interface for deploying NixOS systems based on flakes. It automatically discovers hosts from your flake configuration and provides a one-step command to deploy or inspect those machines.
Features include direct SSH access to target machines, running shell commands remotely, machine reboots with ping-based status monitoring, per-node deployment logging, and flagging outdated systems.
The tool is designed for hobbyists and NixOS users managing small infrastructure setups — clusters or homelabs with up to a few dozen machines — especially during development and testing phases when rapid iteration on configurations is needed.

Requires a NixOS flake configuration. Designed for small-scale deployments; for larger infrastructure, consider dedicated deployment solutions.

labcoat was created by jhillyerd and is written in Go.
