Antigravity vs Cursor: The Ultimate 2025 AI Code Editor Comparison Guide

As AI technology rapidly evolves, AI code editors have become essential tools for modern developers. In 2025, two of the most prominent AI programming tools—Google Antigravity and Cursor—are leading the industry transformation. This article provides an in-depth comparison of these two tools to help you choose the best AI coding assistant.

Core Philosophy: Augmentation vs Automation

Cursor: AI-Augmented Code Editor

Cursor adopts an "AI-first" design philosophy that augments rather than replaces manual coding. In Cursor's workflow, developers remain in control:

You type, and the AI predicts your next 10 lines
You highlight code, and the AI refactors it instantly
You maintain full control over your code

Cursor's goal is to make you a more efficient programmer, not to replace your programming work.

Antigravity: Autonomous Development Platform

Google Antigravity takes an "Agent-First" approach, aiming to automate entire development tasks. Google believes that coding itself is the bottleneck, and their goal is to elevate developers from "code writers" to "system architects."

Antigravity is more than just a code assistant—it's a complete development platform where AI agents can work autonomously across editors, terminals, and embedded browsers.

Core Features Comparison

Cursor 2.0 Key Features

1. Composer Model

Cursor's proprietary AI model, optimized specifically for coding
Average task completion time around 30 seconds
Supports multiple AI models: GPT-4, GPT-4o, Claude Sonnet 3.5, and Claude Opus

2. Multi-Agent Parallel Processing

Supports up to 8 parallel agents
Isolated workspaces using git worktrees or remote environments
Fast, developer-guided multi-agent workflows

3. Embedded Browser Tool

Agents can interact with browsers embedded in the IDE
Inspect DOM elements
Test UI flows

Antigravity Key Features

1. Complete Development Platform

Built as a fork of Visual Studio Code
Supports multiple AI models: Gemini 3 Pro, Claude Sonnet 4.5, Claude Opus 4.5, and open-source variants
Management interface to spawn, observe, and orchestrate autonomous agents

2. Massive Context Window

Gemini 3 natively handles over 1 million tokens
Understands entire monorepos without truncation
Accurately refactors large codebases on first attempt

3. Agent-Driven Automation

Fully autonomous task planning and execution
Coordinated work across editor, terminal, and browser
End-to-end development with minimal supervision

Performance & Speed Comparison

Task Completion Speed

Cursor: Average task completion time around 30 seconds (using Composer model)
Antigravity: Next.js + Supabase backend feature development averages 42 seconds, faster than Cursor's 68 seconds

Codebase Understanding

Cursor: Requires context pruning or multiple iterations for large codebases
Antigravity: With Gemini 3's 1 million token context window, understands entire monorepos in one go

Benchmark Results

Antigravity shows strong performance in early benchmarks post-launch:

SWE-bench Verified: 76.2%
Terminal-Bench 2.0: 54.2%

Pricing Comparison

| Tool | Pricing | Description | |------|---------|-------------| | Antigravity | Free | Google's free agent-first IDE | | Cursor | $20/month (Pro) | Practical usage almost always requires Pro subscription |

For budget-conscious developers and teams, Antigravity's free pricing strategy is highly attractive.

Use Case Recommendations

Choose Antigravity For

✅ Autonomous Scaffolding & Boilerplate: Rapidly generate multi-layer project structures ✅ Exploratory Development: Prototype phase where development speed is critical ✅ Large Codebase Refactoring: Need to understand and modify entire monorepos ✅ Budget-Sensitive Projects: Free tools offer better cost-effectiveness

Choose Cursor For

✅ Precise Editing & Refactoring: Detailed modifications near critical paths ✅ Strict Repo Conventions: Need to follow rigorous coding standards ✅ Daily Coding Tasks: Safety and small, manageable diffs are essential ✅ VS Code Users: Existing extensions, themes, and shortcuts migrate directly

Market Performance & Adoption

Cursor's Commercial Success

As of November 2025, Cursor has achieved remarkable commercial success:

Annualized revenue exceeding $1 billion
Valuation reaching $29.3 billion

Antigravity's Market Position

As a new product launched on November 18, 2025, alongside Gemini 3, Antigravity is rapidly gaining market attention. While large-scale quality comparison data is not yet available, early benchmarks show strong performance.

Browser Integration Comparison

Cursor

Provides embedded browser within the editor
Supports DOM inspection
Test UI directly in the IDE

Antigravity

Uses recording and agent-driven browser interaction
Browser automation via extension
More focused on end-to-end automated testing

Conclusion: Which Should You Choose?

Choosing between Antigravity and Cursor depends on your development style and project needs:

Choose Cursor if you:

Prefer to maintain full control over your code
Need fast, parallel multi-agent workflows
Are already a VS Code user
Are willing to pay for a mature tool

Choose Antigravity if you:

Want AI to handle more autonomous development tasks
Need to understand and work with large codebases
Seek maximum development speed and automation
Prefer free AI programming tools

Both tools represent the future of AI-assisted development. The choice ultimately depends on your personal preferences and project requirements. Regardless of which you choose, AI has become an indispensable part of modern software development.
