# Introduction
|
||
|
|
|
||
|
|
**Colmena** is a simple, stateless [NixOS](https://nixos.org) deployment tool modeled after [NixOps](https://github.com/NixOS/nixops) and [morph](https://github.com/DBCDK/morph), written in Rust.
|
||
|
|
It's a thin wrapper over Nix commands like `nix-instantiate` and `nix-copy-closure`, and supports parallel deployment.
