Community Feedback
Strengths
- Deep feature set: Agent Skills, Hooks, Subagents (with nesting), and MCP support (local and remote)
- Shares a runtime with the Antigravity 2.0 desktop app; sessions and preferences sync bidirectionally
- SSH-aware authentication designed for remote development workflows
- Generous free individual tier with access to multiple frontier model families
Weaknesses
- Closed-source despite a public GitHub repo, unlike the Apache-2.0-licensed Gemini CLI it replaces
- Forces migration off Gemini CLI for free/Pro/Ultra individual users as of June 2026
- Aggressive ToS enforcement has caused bans affecting shared backend access (including Gemini CLI/Code Assist)
- Beta-stage product with an actively growing issue backlog (500+ open issues)

When to Use
Best for: Developers already in the Google ecosystem (Google AI Pro/Ultra, Google Cloud) wanting a terminal agent with deep skills/hooks/subagent support
Avoid when: Team relies on Gemini CLI's open-source (Apache-2.0) nature or wants full multi-vendor model neutrality without a Google account
