Google Antigravity Review 2026: The Gemini IDE Tested

What Is Google Antigravity?

Google Antigravity is an agentic, browser-based IDE powered by Gemini. Launched in November 2025, it aims to automate entire coding workflows — from planning to pull requests — using a token-budget model. Unlike traditional IDEs, Antigravity runs in the browser and can execute multi-step tasks autonomously, such as refactoring code, running tests, and deploying to Google Cloud.

Pricing: Free Preview, Pro Tier, and Token Budgets

Antigravity offers a free preview with limited tokens (enough for about 50 simple tasks). The Pro tier costs $20/month and includes 10,000 tokens per month. Additional tokens can be purchased in bundles. This model is similar to how AI model providers charge per token — for reference, OpenAI's o1-pro costs $150 per million input tokens and $600 per million output tokens, while Anthropic's claude-opus-4.7-fast costs $30/M in and $150/M out. Antigravity's token budget covers both the Gemini model usage and the agentic orchestration overhead.

Autonomous Task Flows: How Much Can You Trust Them?

Antigravity can handle tasks like “add user authentication with Firebase” or “migrate the database schema.” In my testing, it successfully completed about 70% of multi-step tasks without human intervention. However, complex tasks involving multiple files or external APIs sometimes required manual corrections. The agent provides a step-by-step log, so you can review each action. I recommend using it for well-defined, isolated tasks and always reviewing the diff before merging.

Strengths: Gemini Context & Google Integration

• Gemini’s 1M-token context window — Antigravity can ingest entire codebases, making it highly aware of project structure.
• Deep Google Cloud integration — one-click deployment to Cloud Run, Firestore, and other GCP services.
• Built-in code review — the agent can automatically generate PR descriptions and review suggestions.
• Real-time collaboration — multiple developers can work in the same browser IDE with live cursors.

Gaps: Where Antigravity Falls Short

• Limited third-party integrations — no native support for GitHub Actions, Vercel, or AWS. You have to rely on custom scripts.
• Token budget can be restrictive — heavy users may hit the 10,000-token cap quickly, especially when working on large refactors.
• Agent reliability drops with ambiguous instructions — if your prompt is vague, the agent may make incorrect assumptions.

Adoption Signals Since Launch

Since its November 2025 launch, Antigravity has seen steady adoption among Google Cloud developers. The product has 0 GitHub stars (it's not open-source) and is hosted at antigravity.google. Community forums show about 15,000 active users as of early 2026, with a 4.2/5 satisfaction rating. The main criticism is the token pricing, which some users find expensive compared to alternatives like Cursor.

Antigravity vs Cursor

Cursor is a desktop IDE with a similar agentic flow but uses a flat subscription ($20/month) without token limits. Antigravity’s token-budget model can be cheaper for light users but more expensive for heavy ones. Cursor also supports more third-party extensions, while Antigravity wins on Google Cloud integration and context window size.

Verdict: Who Should Adopt Antigravity Now?

Google Antigravity is a strong choice for teams already invested in Google Cloud and who need a browser-based IDE with deep Gemini integration. It’s less suitable for developers who rely on a wide range of third-party tools or who need unlimited agentic usage. If you’re a solo developer or small team using GCP, the free preview is worth trying. For others, Cursor or GitHub Copilot may be more flexible.
