Simple! Run without any parameters, you get a name:

> names

Need more? Tell it how many:

> names 10

Not random enough? How about adding a 4-number pad:

> names --number 5

If you're ever confused, at least there's help:

> names --help
names 0.11.0
Fletcher Nichol <fnichol@nichol.ca>

A random name generator with results like "delirious-pail"

    names [FLAGS] [AMOUNT]

    <AMOUNT>    Number of names to generate [default: 1]

    -h, --help       Prints help information
    -n, --number     Adds a random number to the name(s)
    -V, --version    Prints version information


install.sh (Pre-Built Binaries)

An installer is provided at https://fnichol.github.io/names/install.sh which installs a suitable pre-built binary for common systems such as Linux, macOS, Windows, and FreeBSD. It can be downloaded and run locally or piped into a shell interpreter in the "curl-bash" style as shown below. Note that if you're opposed to this idea, feel free to check some of the alternatives below.

To install the latest release for your system into $HOME/bin:

curl -sSf https://fnichol.github.io/names/install.sh | sh

When the installer is run as root the installation directory defaults to /usr/local/bin:

curl -sSf https://fnichol.github.io/names/install.sh | sudo sh

A nightly release built from HEAD of the main branch is available which can also be installed:

curl -sSf https://fnichol.github.io/names/install.sh \
    | sh -s -- --release=nightly

For a full set of options, check out the help usage with:

curl -sSf https://fnichol.github.io/names/install.sh | sh -s -- --help

GitHub Releasees (Pre-Built Binaries)

Each release comes with binary artifacts published in GitHub Releases. The install.sh program downloads its artifacts from this location so this serves as a manual alternative. Each artifact ships with MD5 and SHA256 checksums to help verify the artifact on a target system.

Docker Image

A minimal image ships with each release (including a nightly built version from HEAD of the main branch) published to Docker Hub. The entrypoint invokes the binary directly, so any arguments to docker run will be passed to the program. For example, to display the full help usage:

docker run fnichol/names --help

Cargo Install

If Rust is installed on your system, then installing with Cargo is straight forward with:

cargo install names

Docker images

If Docker is more your speed, there's a speedy teeny tiny image (~1MB) on the Docker hub at fnichol/names. It's pretty easy to get started:

> docker run fnichol/names 4

From Source

To install from source, you can clone the Git repository, build with Cargo and copy the binary into a destination directory. This will build the project from the latest commit on the main branch, which may not correspond to the latest stable release:

> git clone https://github.com/fnichol/names.git
> cd names
> cargo build --release
> cp ./target/release/names /dest/path/


This crate provides a generate that constructs random name strings suitable for use in container instances, project names, application instances, etc.

The name Generator implements the Iterator trait so it can be used with adapters, consumers, and in loops.


This crate is on crates.io and can be used by adding names to your dependencies in your project's Cargo.toml file:

names = { version = "0.12.0", default-features = false }


Example: painless defaults

The easiest way to get started is to use the default Generator to return a name:

use names::Generator;

let mut generator = Generator::default();
println!("Your project is: {}", generator.next().unwrap());
// #=> "Your project is: rusty-nail"

If more randomness is required, you can generate a name with a trailing 4-digit number:

use names::{Generator, Name};

let mut generator = Generator::with_naming(Name::Numbered);
println!("Your project is: {}", generator.next().unwrap());
// #=> "Your project is: pushy-pencil-5602"

Example: with custom dictionaries

If you would rather supply your own custom adjective and noun word lists, you can provide your own by supplying 2 string slices. For example, this returns only one result:

use names::{Generator, Name};

let adjectives = &["imaginary"];
let nouns = &["roll"];
let mut generator = Generator::new(adjectives, nouns, Name::default());

assert_eq!("imaginary-roll", generator.next().unwrap());
