Install

VS Code, Cursor, Windsurf, Antigravity

All four use the VS Code VSIX format. Either:

From the UI — Extensions panel → ··· menu → Install from VSIX… → pick the .vsix.
From the CLI — code --install-extension hanzo-ai-vscode-v1.9.31.vsix (swap code for cursor, windsurf, or the Antigravity CLI).

JetBrains (IntelliJ, GoLand, PyCharm, WebStorm, …)

Download hanzo-ai-jetbrains-v1.9.31.zip — do not unzip it.
Settings → Plugins → ⚙ → Install Plugin from Disk…
Select the ZIP and restart the IDE.

JupyterLab

pip install hanzo_jupyter-1.9.31-py3-none-any.whl

Restart JupyterLab; the Hanzo panel appears in the sidebar.

Open the Hanzo panel and Sign in with Hanzo, or set your hk- key in the extension settings (hanzo.apiKey).

One identity, everywhere. Sign in with Hanzo (IAM OAuth) or paste a hk- API key. The same credential works in every Hanzo surface — see Integrations & Extensions.
