OpenCode is an open source AI coding agent written in TypeScript that provides automated assistance for software development tasks. The project is hosted at opencode.ai and distributed via npm as the opencode-ai package.
The repository implements a multi-agent architecture that allows developers to switch between different operational modes using the Tab key. The build agent serves as the default mode with full access for development work, while the plan agent operates in read-only mode for code analysis and exploration, denying file edits by default and requesting permission before executing bash commands. A general subagent is also included for handling complex searches and multistep tasks, invoked through @general mentions in messages. This design allows users to choose the appropriate level of autonomy based on their use case, whether performing active development or safely exploring unfamiliar codebases.
OpenCode is available as both a command-line tool and a desktop application in beta. The desktop version supports multiple platforms including macOS with both Apple Silicon and Intel architectures, Windows x64, and Linux through .deb, .rpm, and AppImage formats. Installation can be customized through environment variables that respect a priority order, allowing users to specify custom installation directories or fall back to standard system paths like XDG Base Directory compliant locations or the user's home directory.
OpenCode is classified across multiple technical domains including serverless architecture, full-stack development, web applications, cloud architecture, code samples, API endpoints, user authentication, React ecosystem integration, AWS services, and project templates. The codebase is organized into packages including a console application with asset management. The project maintains documentation at opencode.ai/docs and actively encourages community contributions through a dedicated contributing guide. The README is available in 24 languages, reflecting the project's international reach. OpenCode shares contributors with major projects including Microsoft's VSCode and TypeScript repositories, as well as Anthropic's Claude Code project, indicating significant overlap in the developer ecosystem.
