What OpenCode is
OpenCode is an open-source AI coding agent for working in a terminal, an IDE, or a desktop app. It combines chat assistance and agent mode with terminal access and codebase indexing. The software supports more than 75 LLM providers through AI SDK and Models.dev, as well as local models. It can load language servers for the selected model and let multiple agents work in parallel on one project. OpenCode is available on the web and for Linux, macOS, and Windows, with extensions for Visual Studio Code, Cursor, Zed, Windsurf, and VSCodium. GitHub and GitLab integrations are also listed. Users can share a session with a link; conversations are private by default. The homepage says OpenCode does not store code or context data. The free plan includes the open-source agent and free models, or users can connect a model provider. OpenCode Go costs $10 a month and lists usage allowances of $12 per five hours, $30 per week, and $60 per month. Zen is pay as you go, while Enterprise offers organization deployment, SSO, and internal AI gateway integration; its price is available by contacting the maker. The site footer attributes OpenCode to Anomaly.
