An important update: Transitioning Gemini CLI to Antigravity CLI

Source: Google Developers Blog

When we shipped Gemini CLI last year, our goal was to bring the magic of Gemini directly into your terminal. Along the way, we learned a lot from our community of millions of users, with over 100 000 GitHub stars, 6 000 merged pull requests, and hundreds of contributors.

Gemini CLI proved the terminal could be an incredible interface for agentic tasks, but your needs shifted. You now require multiple agents communicating with each other to split up the work and solve complex problems. This means your terminal tools need to share a unified backend with the rest of your workflow.

Listening to your feedback made one thing clear: we can serve you best by pouring our energy into a single product built for today’s multi‑agent reality. To deliver the platform you need, we’re unifying our efforts into Google Antigravity—our premier agent‑first development platform, which includes a powerful server‑side harness and a brand‑new terminal experience: Antigravity CLI.

Antigravity CLI keeps the most critical features of Gemini CLI: Agent Skills, Hooks, Subagents, and Extensions (now as Antigravity plugins). Whether you use Gemini CLI to get quick answers, scaffold a new coding project, or provision cloud infrastructure, you can still do all of that right in Antigravity CLI.

Key improvements

• Faster execution – Built in Go, Antigravity CLI is snappier and more responsive.
• Asynchronous workflows – Orchestrates multiple agents for complex tasks in the background, letting you run large‑scale refactors or research several topics without locking up your terminal session.
• Unified architecture – Shares the same agent harness as Antigravity 2.0, the new Antigravity desktop application, ensuring that all future improvements to core agents are automatically applied wherever you use them.

Important timeline for consumers

• Today – Antigravity CLI is available to everyone.
• June 18 2026 – Gemini CLI and Gemini Code Assist IDE extensions will stop serving requests for Google AI Pro and Ultra, as well as the free‑of‑charge Gemini Code Assist for individuals.
• June 18 2026 – For Gemini Code Assist for GitHub, no new installations on GitHub organizations will be allowed, and requests will stop being served in the following weeks.

We’re here to help make the transition smooth. Get started now with our technical documentation. Video walkthroughs will be released in the coming weeks.

For enterprise customers

If your organization uses Gemini CLI or our IDE extensions via a Gemini Code Assist Standard or Enterprise license, or uses Gemini Code Assist for GitHub through Google Cloud, your access remains unchanged. We’ll continue to support Gemini CLI and Gemini Code Assist with access to the latest Gemini models and other updates. Gemini CLI will remain accessible via paid Gemini and Gemini Enterprise Agent Platform API keys.

If you’re excited to try Antigravity CLI, you can use it now with your Google Cloud projects.

We welcome your feedback in the Antigravity CLI community forum. We look forward to seeing what you build next with Antigravity 2.0 and Antigravity CLI.
