Oh My Posh provides a configurable prompt engine that can be used from the command line. It supplies a collection of themes and segments that automatically display contextual information such as Git status, cloud service details, programming language versions, and system metrics. The engine adapts its output based on the current working environment, showing relevant data for the task at hand.

Implemented in Go, the engine emphasizes low latency through smart caching and asynchronous processing, allowing complex prompts to render instantly. The design aims for high performance across a range of configurations and multiple segment combinations.

The same configuration file works with many shells—including PowerShell, Bash, Zsh, Fish, and Nu Shell—and runs on Windows, macOS, Linux, WSL, containers, and SSH sessions. This universal compatibility lets users define a prompt once and use it everywhere without needing shell‑specific adjustments.
