Key Takeaways
January 2026 marks a new era in AI-powered development environments. Google Antigravity's November launch disrupted the market with parallel agent orchestration. Windsurf's acquisition by Cognition (Devin AI) brought new agentic capabilities to Cascade AI. Cursor continues iterating on its pioneering agentic features. This comprehensive comparison helps you choose the right IDE for your development needs.
AI IDE Landscape January 2026
The AI IDE market has consolidated around three major players, each with distinct strengths and backing:
Launched: 2023 (pioneer)
Valuation: $29.3B (Nov 2025)
Specialty: Agent mode, Composer
Models: Claude, GPT, custom
Best for: Mature agentic features
Acquired: Cognition (July 2025)
Previously: Codeium
Specialty: Cascade AI, minimal UI
Models: Claude, GPT, custom
Best for: Cost-conscious teams
Launched: November 2025
Company: Google
Specialty: Manager View, 5 agents
Models: Gemini 3 Pro
Best for: Parallel agent orchestration
Google Antigravity: The New Challenger
Google Antigravity, launched November 18, 2025, represents Google's serious entry into the agentic IDE space. Named for its goal to "reduce the gravitational pull of tedious coding tasks," Antigravity brings unique capabilities to the market.
Manager View: 5 Parallel Agents
Antigravity's headline feature is Manager View - the ability to orchestrate up to 5 AI agents working simultaneously on different parts of your codebase:
- Parallel Processing: Each agent works on separate files/components
- Human-in-the-Loop: You review and approve changes from each agent
- Context Sharing: Agents can share context when tasks overlap
- Automatic Conflict Resolution: System detects and handles merge conflicts
Chrome Integration
Deep Chrome integration enables browser automation alongside coding:
- Test your web app directly from the IDE
- Agents can interact with browser for E2E testing
- Screenshot capture for visual debugging
- Network request inspection for API debugging
Antigravity Key Stats
- SWE-bench: 76.2%
- Context: Gemini 3 Pro's 1M tokens
- Pricing: Free preview, ~$20/month Pro expected
- Chrome: Native browser integration
Cursor: The Agent Pioneer
Cursor pioneered the agentic IDE category and continues to lead with its $29.3 billion valuation (November 2025). Its Agent mode and Composer multi-file editing set the standard for AI-assisted development.
Key Features
- Agent Mode: Fully autonomous coding with file system access
- Composer: Multi-file editing with natural language instructions
- Supermaven Autocomplete: Acquired for best-in-class completions
- Model Flexibility: Claude, GPT, and custom model support
- MCP Integration: Model Context Protocol for tool connections
Why Developers Choose Cursor
- Most Mature: 2+ years of agentic development experience
- Community: Largest user base and ecosystem
- Reliability: Battle-tested on production codebases
- Model Diversity: Use Claude for quality, GPT for speed
Windsurf: The Cognition Acquisition
Windsurf's acquisition by Cognition (Devin AI) in July 2025 transformed the competitive landscape after an earlier OpenAI deal collapsed. Previously Codeium's IDE, Windsurf now benefits from Cognition's advanced AI agent technology while maintaining its Cascade AI and competitive $15/month pricing.
Cascade AI Technology
- Deep Context: Maintains understanding across entire projects
- Autonomous Agent: Can implement features across multiple files
- Minimal UI: Designed for "flow state" development
- Model Flexibility: Supports Claude, GPT, and other leading models
Post-Acquisition Changes
- Devin AI Integration: Enhanced agentic capabilities from Cognition's flagship product
- Enterprise Features: Enhanced security and compliance
- Pricing Maintained: Still $15/month, undercutting Cursor
- Team Focus: Improved collaboration features
