OpenChamber VS Code Extension

OpenCode AI coding agent, right inside your editor. No tab-switching, no context loss.

VS Code Extension

Like the extension? There's also a desktop app and web version with even more features.

What you get

Chat beside your code — responsive layout that adapts to narrow and wide panels
Agent Manager — run the same prompt across multiple models in parallel, compare results side by side
Right-click actions — add context, explain selections, and improve code in-place
Click-to-open — file paths in tool output open directly in your editor; edit-style results land in a focused diff view
Session editor panel — keep chat sessions open alongside files
Theme-aware — adapts to your VS Code light, dark, and high-contrast themes

Plus everything from the shared OpenChamber UI: branchable timeline, smart tool UIs, voice mode, Git workflows, and more.

Command	Description
`OpenChamber: Focus Chat`	Focus the chat panel
`OpenChamber: New Session`	Start a new chat session
`OpenChamber: Open Sidebar`	Open the OpenChamber sidebar
`OpenChamber: Open Agent Manager`	Launch parallel multi-model runs

Select code in the editor, right-click, and find the OpenChamber submenu:

Action	Description
Add to Context	Attach selection to your next prompt
Add Comment	Open a comment thread on the selected lines. The comment stays anchored in the editor and goes out with your next message as a context card. The gutter `+` does the same once the extension is active
Explain	Ask the agent to explain the selected code
Improve Code	Ask the agent to improve the selection in-place

Setting	Default	Description
`openchamber.apiUrl`	(empty)	URL of an external OpenCode API server. Leave empty to auto-start a local instance.
`openchamber.opencodeBinary`	(empty)	Absolute path to the `opencode` CLI binary. Useful when PATH lookup fails. Requires window reload to apply.

bun run vscode:dev

bun run vscode:dev now starts watchers + opens an Extension Development Host automatically. Webview UI changes use Vite HMR automatically.

Optional overrides:
