Charm

Charm, the company behind the charmbracelet open source ecosystem, makes the command line glamorous with a suite of Go based terminal libraries and tools. Its flagship agentic product is Crush, a terminal native AI coding agent that connects to large language models and gives them tools to read, write, and execute code directly in the terminal. Crush stands out for serious model provider flexibility, letting developers choose among Anthropic, OpenAI, Gemini, Bedrock, Copilot, Vertex, Groq, and local models and switch mid session, with a Catwalk provider database that keeps model metadata current. It pulls in code intelligence through Language Server Protocols, reads project context files, persists sessions and history in SQLite, extends through Model Context Protocol servers and agent skills, and gives teams fine grained control over permissions and repo local configuration. Because it runs locally in the terminal it supports air gapped and local model workflows, and it works across macOS, Linux, Windows, and the BSDs.
