AntigravityPiChoose 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.
Give your chosen agent more room to build, test and iterate. Standard Compute stretches your compute through automatic provider selection and smart routing. Plans start at $19/month with $20 in monthly compute. Choose your agent below to connect. Eligible new accounts can try $0.25 of compute with no card.

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.
