The free alternative to Gemini CLI
A free CLI agent that doesn’t make you bring a Gemini key — and lets you pick the model per task.
In short
- Gemini CLI is great, free during preview, and locked to one model family — Google Gemini.
- Freebuff is also free, supports many models (MiMo 2.6 Flash as the default, GLM 5.3 Flash, DeepSeek V4.1 Flash, GPT-6 Luna, Gemini 3.8 Flash, and more), and ships 9 specialized subagents.
- Gemini CLI requires a Google Cloud / Gemini API key. Freebuff requires nothing.
- Both run locally and edit files in your terminal.
Google’s Gemini CLI is a polished free preview of "what if Google had Claude Code?" Freebuff is a free CLI agent that doesn’t make you pick one vendor’s model.

When Freebuff wins
- You don’t want a Google account on file.

- You want browser-use, code review, and deep-thinking subagents in the box.

Questions
Will the Gemini CLI preview stay free?
Probably not at current quotas. Google has historically introduced paid tiers once preview tools graduate. Freebuff is free as a permanent commitment, supported by CLI ads.
Can I use Gemini models inside Freebuff?
Yes — Freebuff routes its file-picker through Gemini Flash Lite. Direct Gemini selection from
/model is on the roadmap.
