Best alternatives to Antigravity CLI in 2026
Google's answer to terminal-native AI coding agents, Antigravity CLI brings the same reasoning engine behind Google's Antigravity IDE into a lightweight command-line tool — install it, point it at your terminal, and it can read your codebase, propose edits across multiple files, and run commands, all without leaving the keyboard. Antigravity CLI is installed via a one-line curl/PowerShell script and runs as the `agy` command, offering multi-step reasoning, multi-file editing, tool calling, and persistent history, optimized for keyboard-driven workflows and remote SSH sessions with minimal resource overhead. It's powered primarily by Google's Gemini models, with optional support for Claude and open-source backends, and includes MCP (Model Context Protocol) support and parallel subagent orchestration for concurrent tasks. It replaced the free Google-account login path that made Gemini CLI popular, which was discontinued in June 2026. As of its public preview, it's free with metered usage (community reports suggest a ceiling of low tens of requests per day), with paid headroom available through Google's AI Pro ($20/month), Ultra ($100/month, ~5x quota) and Ultra Max ($200/month, ~20x quota) subscriptions, or $0.01 top-up credits.
