TL;DR

A simple command-line tool that creates and manages cloud servers (VMs) with one-word commands like up and down, without complex dashboards or configuration. Built for developers who want a fast, opinionated way to spin up a cloud machine.

Wtf does this do

hostctl is a command-line tool that lets you spin up cloud servers (virtual machines) quickly and easily, without dealing with complex cloud dashboards or configuration systems. Think of it as a shortcut for developers who just want to get a server running in the cloud and start using it right away. You run simple commands like "up" to create a server and "down" to delete it. You can also list your servers, resize them, or SSH directly into one. It works with providers like DigitalOcean and Amazon EC2. You configure it by setting environment variables for things like which provider to use, what region the server should live in, and what size or "flavor" the machine should be. This is built for developers who need a fast way to launch VMs for development or personal projects. For example, if you want to test something on a fresh Linux machine in the cloud, you could use this tool to get one up and running in seconds. The project is very clear about what it is not: it does not manage production infrastructure or complex server clusters. If you need that, the README points you toward a heavier tool like Terraform instead. The tool is opinionated, meaning it makes decisions for you to keep things simple, and it only manages the VM hosts themselves. It does not handle networking, storage, or other cloud resources. This narrow focus is the main tradeoff, you get speed and simplicity, but if you need anything beyond basic server provisioning, you will need another tool.

Yoink these prompts

Prompt 1
Install hostctl on my machine and configure it to use DigitalOcean so I can create a cloud server with a single command.
Prompt 2
Show me how to set the environment variables for hostctl to launch a small EC2 instance in a specific region and SSH into it.
Prompt 3
Create a script that uses hostctl to spin up a VM, run a setup task, and then tear the server down automatically.
Prompt 4
Compare hostctl to Terraform and explain when I should use hostctl instead of a full infrastructure-as-code tool.
