Gemini CLI Review 2026: Who Can Still Use It?
🇺🇸Gemini CLI remains open source, but consumer service ended June 18, 2026. Review the enterprise and paid API access paths, features, and migration tradeoffs.
What Is Gemini CLI?
Gemini CLI is Google’s Apache 2.0 terminal agent with built-in tools for file operations, shell commands, web fetching, Google Search grounding, and MCP servers. Google changed how it can be used in June 2026. Free Google-account access and request service through consumer Google AI Pro and Ultra plans ended on June 18. The client remains supported for Gemini Code Assist Standard and Enterprise customers and through paid Gemini or Gemini Enterprise Agent Platform API keys.
What Sets It Apart
The open-source client is now the main reason to choose Gemini CLI. Teams can inspect tool calls, audit the code, and maintain a fork for internal requirements. The 1M-token context window can hold substantial parts of a repository, while MCP support connects the agent to databases, internal APIs, and custom tools.
For an individual developer without a paid API key, Antigravity CLI is now Google’s supported path. Our Gemini CLI versus Google Antigravity migration comparison covers the access and workflow tradeoffs. Google preserved Agent Skills, Hooks, Subagents, and Extensions under the Antigravity plugin model, but warned that feature parity was not complete at launch. Existing workflows need testing before migration.
Gemini CLI is still tied to Gemini models, and the old zero-cost consumer proposition is gone. Aider is the closer fit when model choice and an open-source client matter. Antigravity CLI is the practical Google option for personal accounts and Google AI subscribers.
Who It’s For
- Organizations with Gemini Code Assist Standard or Enterprise licenses
- Teams using paid Gemini or Gemini Enterprise Agent Platform API keys
- Developers who need an Apache 2.0 terminal client they can inspect or modify
- Existing Gemini CLI users validating a move to Antigravity plugins
- Individual developers should choose Antigravity CLI unless they specifically need Gemini CLI and accept paid API usage
