OpenCode is a free and open-source artificial intelligence coding agent developed by Anomaly Innovations. It connects large language models with software projects and development tools, allowing users to inspect, modify, optimize source code, run script commands, tests, and perform other programming tasks through natural-language instructions. OpenCode can be used through a terminal, desktop application, or integrated development environment (IDE), and supports models from more than 75 providers, including Anthropic, Google, and OpenAI, as well as locally hosted models.
OpenCode is developed by Anomaly Innovations, the team behind the serverless development framework SST. The active version of OpenCode is primarily written in TypeScript and uses Bun. It is distinct from an earlier Go-based project of the same name that was archived in September 2025. In February 2026, Anthropic clarified that consumer Claude subscriptions could not be used through unauthorized third-party harnesses. OpenCode subsequently removed support for using Claude Pro and Max subscription credentials, while continuing to support access to models through other methods and providers.
