Google incites developers to switch from Gemini CLI to the newly-launched Antigravity CLI

Google has announced it is discontinuing Gemini CLI, merging its functionality into the newly launched Antigravity CLI as part of their agent-first Antigravity platform. This change aims to deliver a unified developer experience, shifting all efforts and support to Antigravity CLI and its server-side harness. While feature parity is not complete from the outset, Antigravity CLI retains the most critical Gemini CLI features, such as agent skills, hooks, subagents, and extension support, reintroduced as Antigravity plugins.

Antigravity CLI is built in Go and offers a faster, more responsive interface. It can orchestrate multiple agents in the background, enabling developers to handle complex code refactors or multi-topic research without blocking their terminal. The tool shares its agent harness with Antigravity 2.0, the new desktop app, allowing core agent improvements to propagate automatically across supported platforms.

Developers can continue workflows like code scaffolding, cloud provisioning, and quick Q&A in the new CLI. Antigravity CLI is available to all users starting today. However, Gemini CLI and Gemini Code Assist IDE extensions will stop serving requests for all tiers, including GitHub organizations, on June 18, 2026.
