OpenCode

OpenCode is an open-source AI coding agent used by hundreds of thousands of developers to run AI coding workflows in the terminal and web. It emphasizes privacy by not storing code or context data, and it supports free built-in models or connections to external providers (including Claude, GPT, Gemini). OpenCode is installable via common package managers and can be used without an account, email, or credit card.
