Verdict: Antigravity or Roo Code?

Updated 2026-08-03

Choose Google Antigravity if you are developers who want to try the most agentic IDE experience available today. Choose Roo Code if you are power users who want a deeply configurable VS Code agent and don't mind tuning it.

In our editorial scoring, Google Antigravity leads in 5 of six categories (output quality, autonomy, speed, value and ease of use), while Roo Code leads in 1 (reliability). On price, Google Antigravity runs free public preview and is proprietary; Roo Code runs free (byo api key) and is open source.

In-Depth Comparison

Google Antigravity Overview

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.

Roo Code Overview

Roo Code began as a fork of Cline and grew into its own power-user favourite. Its signature feature is modes: switchable personas like Architect (plan), Code (build), and Debug (fix), plus fully custom modes with their own prompts and tool permissions. It supports auto-approval settings for hands-off runs, MCP servers, and any OpenAI-compatible provider. The trade-off for all that configurability is a steeper setup than Cline — and, like every BYO-key agent, your API bill scales with how hard you run it.
