Antigravity vs Windsurf vs Cursor
The 2025 AI IDE Benchmark. Windsurf (formerly Codeium) is surging. Cursor is the incumbent. Antigravity is the challenger.
| Feature | Antigravity | Windsurf | Cursor |
|---|---|---|---|
| Core AI Model | Gemini 3 Pro | GPT-5 Codex (Preview) | Claude 3.5 Sonnet |
| Context Window | 2,000,000+ Tokens | Variable 'Deep Context' | 200,000 Tokens |
| Agent Type | Autonomous Planning | Flows (Cascade) | Chat-Assisted |
| Knowledge Base | Native Google Search | Indexed Local Code | Indexed Local Code |
| Pricing | Free (Preview) | $15/mo (Early Bird) | $20/month |
Why Antigravity?
The Context King. If you have a massive repo and need an agent to understand everything at once, Gemini 3's 2M context window is unbeatable. The "Planning Mode" is also unique for complex tasks.
Antigravity excels in enterprise environments with complex codebases spanning multiple modules, microservices, and legacy systems. Its massive context window allows it to maintain awareness of architectural patterns, dependency relationships, and coding standards across your entire project simultaneously.
The native Google Search integration provides real-time access to documentation, Stack Overflow solutions, and GitHub repositories, making it particularly powerful for working with newer frameworks or troubleshooting obscure issues.
Why Windsurf?
The Flow State. Windsurf (by Codeium) feels incredibly fluid. Its "Cascade" feature predicts your next move better than anything else. If you want speed without the heavy "Agent" overhead, pick this.
Windsurf's strength lies in its predictive capabilities and seamless integration with existing workflows. The IDE learns from your coding patterns and anticipates common operations, reducing the mental overhead of context switching between thinking and coding.
Early access to GPT-5 Codex gives Windsurf a significant advantage in code generation quality and understanding of complex algorithmic problems. The "Deep Context" system adapts to your project's specific architecture and coding conventions.
Why Cursor?
The Reliable Choice. It's the most mature. If you rely on VS Code extensions and want a stable, no-nonsense AI pair programmer that rarely hallucinates, Cursor + Claude 3.5 is still the gold standard.
Cursor's maturity shows in its robust extension ecosystem, battle-tested performance, and consistent behavior across different project types. It's the safe choice for production environments where reliability trumps cutting-edge features.
Claude 3.5 Sonnet's conservative approach to code suggestions minimizes the risk of introducing bugs or security vulnerabilities, making Cursor ideal for teams prioritizing code quality and maintainability over rapid prototyping.

Migration Strategies
From VS Code to AI IDEs
1. Gradual Transition Approach
Start by using the AI IDE for new projects or non-critical features. This allows you to learn the interface and AI capabilities without risking existing workflows.
- Week 1: Install and explore with sample projects
- Week 2-3: Use for new feature development
- Week 4+: Gradually migrate existing projects
2. Extension Migration
Most VS Code extensions work across all three IDEs, but some optimizations are IDE-specific:
- Antigravity: Best with minimal extensions (AI provides most functionality)
- Windsurf: Optimized Codeium extensions available
- Cursor: Full VS Code marketplace compatibility
3. Team Coordination
When migrating a team, ensure everyone understands the AI capabilities and limitations:
- Conduct training sessions on AI prompting
- Establish code review guidelines for AI-generated code
- Set up shared configurations and best practices
