Google Migrates Gemini CLI to Antigravity CLI

Google is discontinuing support for its Gemini CLI and Gemini Code Assist IDE extensions for both paid and free users as of June 18, 2026. Developers are now directed to transition to the new Antigravity CLI and Antigravity 2.0. Google plans to provide comprehensive technical documentation and video guides to assist with this migration process.

Context

Google's Gemini CLI and related IDE extensions have been in use by developers for various coding tasks. However, the decision to discontinue these tools points to a strategic shift towards the Antigravity CLI, which is expected to offer enhanced features. The transition timeline allows developers to prepare for the upcoming changes while Google provides resources to facilitate the switch.

Why it matters

The migration from Gemini CLI to Antigravity CLI represents a significant shift in Google's development tools, impacting how developers will interact with Google's coding environment. This change is crucial as it may affect productivity and the learning curve for users transitioning to the new system. Understanding this transition is essential for developers to maintain efficiency in their workflows.

Implications

The discontinuation of Gemini CLI may disrupt current workflows for developers who rely on these tools. Those who do not transition in time may face challenges in their projects. Conversely, successful adoption of Antigravity CLI could lead to improved development processes and capabilities, potentially benefiting users in the long term.

What to watch

As the June 2026 deadline approaches, developers will need to start familiarizing themselves with Antigravity CLI and its functionalities. Google will release technical documentation and video guides, which will be crucial for easing the transition. Monitoring user feedback on these resources will provide insight into the migration's effectiveness.
