Summary

Google officially discontinued the Gemini CLI and its associated Gemini Code Assist IDE extensions for individual users as of June 18, 2026. This significant change mandates a complete migration towards the Google Antigravity CLI (Agy CLI) for developers. The closure marks the end of an era for those who depended on Gemini CLI's agentic workflows for software development, necessitating a swift adjustment to new tools. The article emphasizes that the Agy CLI is notably fast, while also acknowledging potential areas where it may fall short. It aims to guide users through this transition, ensuring their development pipelines remain operational and efficient despite the shift from Gemini to Antigravity.

Key takeaway

For software engineers relying on Google's AI development tools, you must immediately plan your migration from Gemini CLI and Code Assist to the Google Antigravity CLI. As of June 18, 2026, these tools are discontinued for individual users, meaning your existing agentic workflows will cease to function. Evaluate Antigravity CLI's capabilities and limitations now to ensure a smooth transition and avoid disruptions to your deep work blocks and development pipelines.

Key insights

Google has discontinued Gemini CLI and Code Assist, mandating migration to Antigravity CLI for individual users by June 18, 2026.
