TL;DR

  • Antigravity if you want a complete agent manager and IDE experience.
  • Gemini CLI if you want a terminal CLI or need headless execution.

Quick Comparison

Feature Antigravity IDE Gemini CLI
User Anyone looking to work with agents to build applications and execute tasks on your behalf. Technologists who prefer spending time in the terminal.
Installation Easy graphical install; no prior install required. Quick install with npm install -g @google/gemini-cli (requires Node.js).
Orchestrating Mulitple Agents Agent Manager is a mission control dashboard for running multiple agents. Multiplexing via tmux or separate terminal windows enables running multiple agents.
Spec-Driven Development Opinionated, with rich walkthroughs. Configurable using the Conductor extension.
Extensibility Open VSX extensions, MCP, and Agent Skills. Gemini CLI extensions, MCP, and Agent Skills.
Interface Benefits

Integrated browser to view your application, provide visual feedback, and work more fluidly with the agent.

Native Debugging catches and fixes stack traces.

Headless mode runs without an interactive UI, making it ideal for piping output, CI/CD integration, and automation scripts.

Call local tools like gh or gcloud directly.

 

Still Not Sure?

If you’re still not sure which way to go, the good news is that they are both great options. Antigravity is an approachable option for anyone. With almost 100k stars on GitHub, Gemini CLI has found its fanbase among the developer community. If you like to do your own experimentation, they both have a generous free tier, so you can give them both a try and see what you prefer.
