About Gemini CLI
Gemini CLI is an open-source AI agent from Google that works in your terminal. It was built to query and edit large codebases and automate multi-step work from the command line.
What it does
Gemini CLI can read and change code across a project, generate apps from images or PDFs, and carry out multi-step workflows. Extensions add more capabilities to the CLI. The source is public on GitHub under the Apache 2.0 licence.
Key features
- Query and edit large codebases from the terminal
- Generate apps from images or PDFs
- Automate complex multi-step workflows
- Extensions for extra capabilities

Who it's for
Developers who work in the terminal and want a Google-built agent. People who used the free individual tiers should read the change notice before they start.
Pricing and good to know
The source is Apache 2.0 licensed, but the page says that on June 18, 2026, Antigravity CLI replaced Gemini CLI for unpaid tier and Google One users. The page also says the CLI is not optimized for the newest model, which is available through Antigravity. Check the migration guide before you set up a new workflow.
