Antigravity vs pi
Terminal-based coding agent with a minimal core, 15+ LLM providers, tree-structured session history, and a TypeScript extension system for building your own workflows. Here is how pi ($0/mo open source) stacks up against Antigravity ($15/mo) across cost, hosting, data privacy, and real-world trade-offs.
pi is a verified Open Source-licensed open-source replacement for Antigravity. Switching from Antigravity ($15/mo) saves $180/yr per solo seat, or $900/yr for a 5-person team. Deployment: Runs on Self-host.
The catch: Requires self-hosting setup, updates, and server maintenance compared to managed Antigravity.
