OpenCode for VS Code

OpenCode Workbench brings the OpenCode coding agent directly into VS Code, giving you an AI-assisted development workflow without leaving the editor.

Chat with your codebase, create implementation plans, track subagents, review file changes, fork conversations, undo or restore changes, manage sessions, and monitor provider usage from one interface.

OpenCode Workbench requires the OpenCode CLI to be installed locally.

QUOTA MONITORING

Monitor usage and limits for supported providers, including OpenAI, GitHub Copilot, Z.ai, Google Gemini, Zhipu, and other providers available through OpenCode.

The quota panel displays provider usage, limits, and budget information directly inside VS Code.

OPENCODE INTEGRATIONS
