OpenCode is an open-source AI coding agent designed to assist developers in writing code directly in their terminal, IDE, or through a desktop application. It supports integration with over 75 LLM providers via Models.dev, including popular options like Claude, GPT, and Gemini, and allows use of existing subscriptions such as GitHub Copilot and ChatGPT Plus/Pro. Key features include LSP enablement for automatic language server protocol loading, multi-session support for running multiple agents in parallel on the same project, and shareable session links for debugging or reference. The agent is built with a privacy-first approach, not storing any code or context data, making it suitable for sensitive environments. It is available as a free tool with included models and has a large community, with over 140,000 GitHub stars and 6.5 million monthly developers. Use cases include code generation, debugging, and collaborative coding across various development environments.
