OpenCode

What is OpenCode?

OpenCode is a terminal-native, open-source AI coding agent built by the SST team. The project documentation describes it as provider-agnostic, meaning it can work with any AI model the user chooses. The tool runs entirely inside the command line, offering AI-assisted code generation, explanation, and editing without leaving the terminal. Its source code is hosted on GitHub under the anomalyco/opencode repository, which currently lists 190,226 stars. Additional documentation and usage guides are available at opencode.ai.

Who is OpenCode for?

OpenCode is designed for developers who work primarily in terminal environments and want an AI agent that is not locked into a single model provider. The documentation notes that users can bring their own model, whether it is a local open-weight model, a cloud-hosted endpoint, or a proprietary API. This flexibility makes the tool suitable for individual developers, small teams, and organizations that need to control which models process their code. Because it is open-source, developers can inspect, modify, and extend the codebase. The terminal-native design implies that users should be comfortable with command-line interfaces and text-based development workflows.

How much does OpenCode cost?

OpenCode is free. The pricing page lists a starting cost of $0 per month with no paid tiers. The entire project is open-source, so anyone can download, build, and run the agent at no cost. There are no subscription fees, usage limits, or premium features behind a paywall. Users pay only for any third-party model API calls they choose to run through OpenCode. The GitHub repository contains the full source code under a permissive license, allowing unrestricted use, modification, and redistribution.
