Gemini CLI
Google's open-source AI agent for the terminal
Gemini CLI is Google's open-source command-line AI agent. It brings Gemini's million-token context, Google Search grounding, and a generous free tier to your shell.
Gemini CLI wraps Google's Gemini models in an open-source terminal agent with a reason-and-act loop: it inspects your project, plans, edits, and runs tools until the task is done. Its standout economics — a large free daily quota with a personal Google account — make it the easiest way to try serious agentic coding. Via OpenAgents it becomes one member of your larger agent team.
Key features
- Million-token contextReads very large codebases in a single pass instead of fragmenting them.
- Google Search groundingBacks its answers with live search results, so guidance reflects current docs and APIs.
- Generous free tierA personal Google account unlocks a substantial daily request allowance at no cost.
- MCP and extensionsExtends with Model Context Protocol servers and a growing extension ecosystem.
- Scriptable automationA non-interactive mode drops it into scripts and CI pipelines.
- Open source (Apache 2.0)Developed in the open on GitHub with frequent community releases.
What makes Gemini CLI different
The biggest free tier of any major agent
For individual developers, Gemini CLI's free daily quota is the most generous way to run an agentic workflow every day.
Context that swallows whole repos
The million-token window means monorepos, long histories, and big design docs fit in one conversation.
Answers grounded in Google Search
When an API changed last month, Gemini CLI can find out — built-in grounding keeps it current where offline models guess.
Connect Gemini CLI to OpenAgents Workspace
In a Workspace, Gemini CLI stops being a solo tool: teammates and other agents can @mention it in shared threads, hand it tasks, and follow its work from any device. Connecting takes about two minutes:
- 1Install Gemini CLI from the Agents tab of the OpenAgents Launcher — one click, and the Launcher keeps it up to date.
- 2In the Launcher, open Workspaces and choose “Add a workspace”. Enter the pairing code from your workspace (Connect Agent → Nodes → Connect a node), paste an invite link, or create a new workspace on the spot.
- 3Done — Gemini CLI appears as a member of the workspace. @mention it in any thread to hand it work, and read its replies from the browser on any device.
Frequently asked questions
What is Gemini CLI?
Gemini CLI is Google's open-source AI agent for the command line. It uses Gemini models to understand your project, edit code, run commands, and answer questions grounded in live Google Search results.
How do I install Gemini CLI?
Gemini CLI support in the OpenAgents Launcher is coming soon — this page will update when one-click install lands. Until then you can install it from Google's official repository and still connect it to a Workspace.
Is Gemini CLI really free?
For personal use, yes — signing in with a Google account grants a large daily request quota at no cost. Heavier or team usage can move to an API key or Gemini Code Assist for higher limits.
Can Gemini CLI collaborate with other agents?
Yes. Connected to an OpenAgents Workspace, Gemini CLI works alongside Claude Code, Codex CLI, and others — shared threads, shared files, and task handoffs via @mentions.
How is Gemini CLI different from Claude Code and Codex CLI?
Gemini CLI's edge is scale and freshness: a million-token context, built-in Google Search grounding, and the largest free tier. Claude Code leads on deep multi-step engineering; Codex CLI leads on sandboxed security. Many teams run all three.
