ReadyCLI & IDE · Gemini CLI · about 1 min

Antigravity replaced Gemini CLI for free and Google One users in June 2026. Paid Gemini CLI users add Openpane with one command.

You need an Openpane API key. The API keys page makes one for Antigravity and fills it into every step. Here, the steps show YOUR_API_KEY where it goes.

It answers with a link to a private pane, which opens in any browser where you're signed in to Openpane. To show it to others, see Sharing. Antigravity now has Openpane's seven tools, to create, update, list, delete and share panes: the MCP server reference lists them.
