Google Retires Gemini CLI Today, Pushing Developers to the New Antigravity CLI
As of June 18, Gemini CLI stops serving consumer requests. Google steers developers to the Go-built, multi-agent Antigravity CLI — keeping Skills and Hooks, but dropping open source.
The clock runs out today. As of June 18, 2026, Google's Gemini CLI and the Gemini Code Assist IDE extensions stop serving requests for consumer users — including Google AI Pro and Ultra subscribers and free individual developers — as the company funnels its command-line audience toward the newer Antigravity CLI. The change was announced on May 19, giving developers a one-month window to migrate.
Antigravity CLI is the terminal face of Google Antigravity, an agent-first development platform that shares the same server-side agent harness as the Antigravity 2.0 desktop application. Rebuilt in Go, Google says the new tool is snappier and more responsive than its predecessor, and is designed for what it calls "today's multi-agent reality" — orchestrating multiple agents asynchronously in the background so developers can run large-scale refactors or parallel research without locking up a terminal session.
Most of the features that made Gemini CLI popular carry over: Agent Skills, Hooks, and Subagents all survive the transition, and Extensions return rebranded as Antigravity plugins. Google concedes there "won't be 1:1 feature parity right out of the gate," but says quick grounded answers, project scaffolding, and cloud infrastructure provisioning remain intact. Technical documentation and video walkthroughs are available to ease the switch.
Enterprise users get a reprieve. Organizations on a Gemini Code Assist Standard or Enterprise license — or those using Gemini Code Assist for GitHub through Google Cloud — keep their existing access, ongoing support, and the latest models. For GitHub organization installations of Gemini Code Assist on the consumer tier, however, new deployments stop being accepted today, with service termination to follow shortly after.
The move has drawn pushback on one front: the original Gemini CLI was open-source, and Google has not committed to open-sourcing Antigravity CLI, prompting concern from a community that valued the transparency of the older tool. The retirement also underscores how aggressively the major labs are reframing their developer tooling around autonomous, multi-agent workflows — a race in which Google's Antigravity, Anthropic's Claude Code, and OpenAI's Codex are all jockeying for the same terminal.
