OpenCode

OpenCode is an open source AI coding agent that helps users write code across multiple interfaces including the terminal, desktop app, and IDE extensions. The platform features built-in free models and allows developers to connect to over 75 LLM providers or use existing accounts. It is designed with a privacy-first approach that avoids storing code or context data.

• Available for the terminal, desktop application, and IDE extensions
• LSP enabled to automatically load the right language server protocols for the LLM
• Multi-session support to run multiple agents in parallel on the same project
• Session sharing via links for reference or debugging
• Integration with existing accounts such as GitHub Copilot and ChatGPT Plus or Pro
• Support for 75 plus LLM providers including local models and Zen validated models
• Privacy-first operation that does not store code or context data

Pros

• Offers flexible deployment through terminal interfaces, a desktop app available for macOS, Windows, and Linux, and IDE extensions
• Provides cost flexibility by including free models alongside support for existing subscriptions like GitHub Copilot and ChatGPT
• Maintains strict privacy controls by not storing code or context data for privacy-sensitive environments
• Enables parallel workflows by allowing users to run multiple coding agents simultaneously on a single project

Cons

• Requires checking which specific IDEs are supported by the IDE extensions
• Requires checking separate pricing or access terms if using external providers or the Zen model set
• Depends on internet connectivity and third-party LLM providers unless running local models

OpenCode fits developers and technical teams looking for an open source AI coding assistant that can be used directly inside their preferred terminal, desktop, or IDE environment. It suits users who want to leverage existing AI subscriptions or connect to alternative LLM providers while maintaining privacy. It is a poor fit for teams that require cloud storage of code or context data by the AI tool.

The listing and website state that OpenCode is free and includes free models, while also allowing users to connect external models or use existing subscriptions such as GitHub Copilot and ChatGPT Plus or Pro.

Unlike tools locked to a single proprietary interface or provider, OpenCode operates as an open source agent supporting terminal, desktop, and IDE form factors simultaneously. It stands out by letting developers bring their own existing accounts or choose from over 75 LLM providers rather than forcing a single AI ecosystem.

GitHub, GitHub Copilot, ChatGPT Plus or Pro, LSP, and 75 plus LLM providers through Models.dev including Claude, GPT, Gemini, and local models.

OpenCode is worth trying for developers seeking a flexible, open source AI coding agent with cross-platform support. Its ability to connect to dozens of LLM providers or run free models makes it adaptable for different setups. However, users should verify any external subscription requirements for specific third-party models.
