Cursor has dominated the AI editor space since 2024, but two challengers are climbing fast: Windsurf (from Codeium) and Antigravity. According to LogRocket’s January 2026 power rankings, Antigravity holds the #1 position while Windsurf sits at #2, ahead of Cursor at #3.
What makes these new editors competitive? Are they genuinely better than Cursor, or is the hype ahead of reality? Let’s break down both tools and see how they stack up.
Antigravity: The Feature-Packed Newcomer
Antigravity burst onto the scene with an aggressive feature set that immediately caught developers’ attention. It’s currently free during its preview period, which has accelerated adoption.
Standout Features
Multi-Agent Orchestration: This is Antigravity’s killer feature that no competitor offers. Rather than a single AI assistant, Antigravity coordinates multiple specialized agents:
- Code Agent: Handles implementation and refactoring
- Review Agent: Analyzes code for issues and improvements
- Test Agent: Generates test cases and validates coverage
- Debug Agent: Diagnoses and fixes bugs
These agents work in parallel, allowing you to implement a feature while simultaneously getting test coverage and code review feedback.
Integrated Chrome Browser Automation: Antigravity includes a built-in Chrome instance for autonomous testing. This means:
- AI can write tests that interact with your UI
- Automated end-to-end testing without separate tooling
- Visual regression detection
- Accessibility checks during development
Model Flexibility: Antigravity supports an impressive range of models:
- Gemini 3 Pro (Google’s latest)
- Claude Sonnet 4.5 and Opus 4.5
- GPT-OSS (OpenAI’s open-source variant)
You can switch models per task, using faster models for simple completions and powerful models for complex refactoring.
Live Preview: Real-time preview of web applications as you code, with hot reload and instant updates.
3D Graphics Support: Uncommon in code editors, Antigravity includes Three.js and WebGL preview capabilities, making it appealing for game developers and graphics programmers.
Built on VS Code
Like Cursor, Antigravity is built on Visual Studio Code’s foundation. This means:
- Familiar interface for VS Code users
- Full extension marketplace compatibility
- Proven stability and performance
- Extensive customization options
The Catch
During the preview period, Antigravity is completely free. The company hasn’t announced pricing yet, which creates uncertainty. Will it remain affordable post-launch, or will early adopters face sticker shock?
Windsurf: The Mature Challenger
Windsurf (formerly Codeium Editor) represents Codeium’s evolution from a simple code completion tool to a full-featured AI editor. It officially launched as “Windsurf” in late 2025 and has been gaining traction steadily.
Core Strengths
The Rare Trifecta: Windsurf offers three features that rarely coexist in AI editors:
- Git Integration: Deep Git support with visual diff, merge conflict resolution, and commit assistance
- Live Preview: Real-time preview for web development
- Collaborative Editing: Real-time multiplayer coding sessions
Most editors offer one or two of these. Windsurf delivers all three.
Cascade Tool: Windsurf’s headline feature is Cascade, which can generate complete applications from single prompts. Developers have reported success creating:
- Full-stack CRUD applications
- Authentication systems
- Admin dashboards
- REST APIs with OpenAPI documentation
The impressive part isn’t just generation—it’s that Cascade produces deployable code following modern best practices.
Terminal Integration: Windsurf seamlessly executes shell commands from chat. You can ask “Run the test suite” or “Deploy to staging” and Windsurf will execute the appropriate commands, showing results inline.
Checkpoint System: This innovation allows easy reversion of AI-generated changes. When Cascade makes extensive modifications, you can revert to specific checkpoints without losing all progress. Think of it as granular undo for AI-assisted development.
Free Tier: Unlike Cursor’s limited free tier, Windsurf offers a generous free plan that includes:
- Basic AI completions
- Chat functionality
- Git integration
- Live preview
This makes it accessible for hobbyists and students.
Pricing
Windsurf’s paid plans are competitive:
- Free: Basic features with usage limits
- Pro: $15/mo (cheaper than Cursor’s $20/mo)
- Team: $30/mo per user with collaboration features
