What is runpodctl?

RunPod is a cloud platform for renting GPU computing power, the kind of hardware you need for training AI models or running heavy compute workloads. The runpodctl tool is a command-line utility that lets you manage those cloud GPU instances (called "pods") and transfer files to and from them, all from your terminal instead of through a web interface. The tool does two main things. First, it handles file transfers between computers using simple one-time codes, no API keys or complex setup required. You run a send command on one machine, get a short code like "8338-galileo-collect-fidel," then run a receive command with that code on another machine. Second, it manages your cloud pods: you can list your pods, start them, stop them, and even bid on "spot" pricing where you set the price you're willing to pay (lower cost, but you can get outbid and lose access). Pod management does require an API key from your account. This is for people working with cloud GPUs who prefer typing commands over clicking through a dashboard. A data scientist training models might use it to quickly push a dataset to a pod. A startup running AI inference could script their infrastructure to spin pods up and down automatically. Someone on a budget might set spot bids to grab compute power when prices are low. The project is built in Go and relies on a few open-source libraries, cobra for the command structure, viper for configuration, and notably croc for the file transfer mechanism, which is likely what enables the no-setup, one-time-code approach to moving files between machines.
