Gemini CLI: Once the Most Generous Free Terminal Agent, Now Enterprise-Only

🌏 中文版

Gemini CLI is Google's open source terminal AI agent, built on a ReAct (Reason and Act) loop with built-in tools and MCP servers. For a while it had the most extravagant free tier in this category — and then it stopped serving individual accounts on June 18, 2026.

This post covers what it is, why that free-tier strategy is worth remembering, and who can still use it today.

Where it stands: for individuals, it is gone

The sentence most likely to mislead you: Gemini CLI was not shut down, but if you are an individual user it is gone as far as you're concerned.

These are two separate questions with opposite answers:

• The software is alive. The repo isn't archived, it's Apache 2.0, it was still cutting nightly builds on 2026-08-19, and commits landed the day before.
• The service individuals could use is gone. The "Login with Google" option has been removed — not a quota reduced to zero, but the path itself deleted.

So read the table below as "which row are you in," not "is this product dead":

Google published a separate deprecation notice after the shutdown, and its FAQ answers this directly: "I have a Gemini Code Assist Standard or Enterprise subscription. Am I affected? No, access to Gemini Code Assist IDE extensions and Gemini CLI using Gemini Code Assist Standard or Enterprise subscriptions remain unchanged." The enterprise side is also still receiving features — the Gemini Code Assist release notes shipped Release Channels for Standard and Enterprise on 2026-08-10.

So "is Gemini CLI dead?" has no single answer; it depends who's asking:

If you're an individual who wants a Google agent in the terminal, the answer now is Antigravity CLI.

Installation

# Run without installing
npx @google/gemini-cli

# Global install
npm install -g @google/gemini-cli

Written in Node — a detail its successor changed, as Antigravity CLI is a Go rewrite. Licensed Apache 2.0.

That free tier

This is the part worth remembering. All it took was a Google account:

No credit card, no API key. And it wasn't a stripped-down version — it included the strongest Pro model of the time, the largest context window, and all core features.

How Google arrived at those numbers: they analyzed internal developer usage, found the heaviest consumers, and set the free ceiling at twice that. The message was plain — if even Google's most intensive engineers couldn't exhaust it, virtually no outside developer would ever hit a paywall.

It lasted about a year.

Core features

Search grounding was its most distinctive feature relative to other terminal agents: the agent could pull live information from the web, and it counted against the free tier.

Its relationship to Gemini Code Assist

Agent mode in the VS Code extension was effectively a subset of Gemini CLI, sharing the same core. That's why the 6/18 shutdown swept up the IDE extension and the GitHub version at the same time — they were different shells over one thing.

Two things this episode leaves behind

A free tier is not a moat; it's a marketing budget. Choosing a tool primarily for its free tier stakes your toolchain on somebody else's marketing decision. The most aggressive free offering this category has seen lasted about a year.

Open source doesn't mean it can't be taken away. Gemini CLI is Apache 2.0 and the repo is still there, and none of that helped individual users — because the valuable part was never the source, it was the free inference behind it. A license governs the code, not who is allowed to call the endpoint.

Who it fits

• Teams holding a Gemini Code Assist enterprise license: still a supported path, no need to rush
• Anyone with a paid Gemini API key: keeps working, with model availability following your key
• People studying agent implementations: Apache 2.0 and still maintained, so it's readable reference code
• Individuals looking for a free terminal agent: this door is closed, and there is no paid individual plan that buys it back — using Google's terminal agent means Antigravity CLI

Changelog

• 2026-08-19 (second revision): Re-verified and reframed after being asked "wasn't it shut down?" Saying it "is still a usable product" misleads individual readers — the individual entry point (Login with Google) has been removed, and only enterprise subscriptions are unaffected. Added the software-alive vs individual-service-gone split, two harder sources (the official deprecation FAQ and the release notes), and evidence that the repo still cuts daily nightlies
• 2026-08-19: Restored Gemini CLI as this post's subject. The previous revision rewrote it as an Antigravity CLI introduction, duplicating the site's existing Antigravity CLI post. Coverage of the successor goes back to that post; this one focuses on Gemini CLI itself — its free tier design, the enterprise paths that survive the shutdown, and the two lessons the episode leaves behind
• 2026-08-18: The shutdown became fact; rewrote the content and corrected the install URL
• 2026-05-21: Added the discontinuation notice (2026/06/18) and migration guidance
