Crush is an open-source terminal-based AI coding agent from Charmbracelet. It brings code-aware conversational development into the command line and is designed to connect a developer's tools, source code, workflows, and preferred language models in one terminal interface.

The agent supports multiple LLM providers, switching models while preserving session context, multiple work sessions per project, Language Server Protocol context, and extensions through MCP. It runs across a wide range of operating systems and terminal environments, making it suitable for developers who prefer a keyboard-first workflow.

Crush is useful for coding, repository exploration, debugging, refactoring, and other agentic development tasks without requiring a dedicated AI IDE. Its model flexibility and extensibility make it attractive to developers who want a polished terminal experience while retaining control over providers, tools, and the surrounding workflow.
