Choose Google Antigravity if you are developers who want to try the most agentic IDE experience available today. Choose Pi if you are developers who want a fast, minimal, hackable terminal agent with full control over context and models.
Editorially this matchup is a dead heat: each agent leads in 3 of our six categories. On price, Google Antigravity runs free public preview and is proprietary; Pi runs free (mit) — bring your own model and is open source.
Antigravity is Google's agentic development platform, launched alongside Gemini 3: a VS Code-style IDE where an agent manager dispatches agents that work across the editor, terminal, and a Chrome browser they control — producing verifiable artifacts (plans, screenshots, browser recordings) as they go. The free public preview and Gemini 3 Pro quality made it an instant heavyweight, but it's still early: capacity limits, preview rough edges, and early prompt-injection concerns around the browser-control surface mean production teams should keep a human on the loop.
Pi is an open-source terminal coding agent and agent harness created by Mario Zechner (badlogic, creator of libGDX) and published under MIT by Earendil. Its philosophy is radical minimalism: by default the model gets a small set of tools — read, write, edit, bash — and everything else, from subagents to plan mode, lives in TypeScript extensions. That keeps the loop fast, the context clean, and the behavior fully under your control. It supports 30+ model providers with mid-session switching, session branching and compaction for long tasks, and custom OpenAI-compatible providers via a simple models.json.
Both work with any OpenAI-compatible provider. Point the base URL at Standard Compute and get frontier-model compute with no usage limits from $39/mo flat — no per-token billing, no 429 rate limits.
