Google Antigravity

Description

Google Antigravity is Google's agentic development platform, announced on November 18, 2025 alongside the Gemini 3 launch. It evolves the traditional IDE toward an agent-centric model: it includes an editor, terminal, and browser control, with an Agent Manager that orchestrates multiple agents in parallel and across workspaces. It provides access to Gemini 3 Pro and Flash, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS 120B. Available for macOS, Linux, and Windows. In 2026 it's still considered 'public preview' but with official paid plans: Free ($0), AI Pro ($20/mo), and AI Ultra ($249.99/mo), plus additional credits (2,500 for $25). In March 2026 it sparked controversy over cuts to free-tier limits, something to keep in mind.

Detailed Evaluation

Key advantages

• Agent Manager for multiple parallel agents

  Orchestrates several agents at once across different workspaces, with a central 'mission control' panel to supervise everything.

• Official Gemini 3 Pro access

  It's the official way to work with Gemini 3 inside an IDE, with native integration with Google's most advanced reasoners.

• Real multi-model

  Includes Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS 120B beyond the Gemini models, exceptional for a hyperscaler IDE.

• Built-in browser control

  Agents can navigate the web, fill forms, and validate end-to-end flows without leaving the IDE.

• Accessible free plan

  The Free tier still lets you work with rate limits and try all the models, useful for discovering the tool.

Limitations to consider

• Opaque credit system

  Google doesn't document the credit-to-token ratio; users report unpredictable consumption, especially with Gemini 3 Pro.

• Free tier cuts

  In March 2026 Google reduced the generous launch free-tier limits, triggering public complaints on The Register and forums.

• Still in public preview

  Although functional, it's not marked GA: regressions, API changes, and unexpected behaviors can show up.

• Agentic paradigm curve

  Managing multiple parallel agents requires new practices: diff review, context handling, and constant supervision.

Standout Feature

Antigravity is the first official Google IDE built from scratch for the agentic model: its Agent Manager orchestrates parallel agents across editor, terminal, and browser, combining Gemini 3 with Claude Sonnet/Opus and GPT-OSS in the same environment. No other hyperscaler IDE offers that mix.

Comparison with Alternatives

Against Cursor, Antigravity bets harder on autonomous agents and browser control, with direct access to Gemini 3. Against Warp, it covers the whole IDE (not just the terminal), though with a steeper curve and a less transparent credit system.
