Google pushes most Gemini CLI users toward closed-source Antigravity

Google is moving most Gemini CLI and Gemini Code Assist individual users to Antigravity CLI on June 18, while enterprise-license and paid API-key users can continue accessing Gemini CLI. The replacement is intended to unify Google's command-line agent work and improve multi-agent support, but Google says it will not initially have one-to-one feature parity. Unlike the Apache-licensed Gemini CLI repository, Antigravity's public repository currently exposes documentation rather than the product's source. Developers have objected to the forced migration, usage limits, and the shift from an open tool to a closed replacement. The story matters because it shows how quickly strategic AI developer tools can move from subsidized open distribution toward controlled, paid platforms, creating lock-in and continuity risk for workflows built around them.

Key details: May 20, 2026, June 18 transition, Gemini CLI, Antigravity CLI, No initial 1:1 feature parity, Enterprise and paid API access preserved.
