Antigravity vs Windsurf: How I Actually Split My Work Between Them

When I saw that Cognition had acquired Windsurf, my honest first reaction was to pause and ask myself whether I should keep betting on Antigravity. When a tool is the one you reach for every day as a solo developer, switching is not a decision you make lightly.

This is a comparison from someone who has actually used both, day to day. Rather than ranking spec sheets, I wrote it around a single question: which one do you make your daily driver? The short version is that I still keep Antigravity as my main tool and reach for Windsurf only in specific situations. Below I walk through why, in the order of features, pricing, and agent design.

For context, Cognition's roughly $250 million acquisition of Windsurf in 2026 sharpened the contrast between the two. Windsurf leans into autonomous execution; Antigravity leans into context awareness and explicit control. That difference in philosophy shows up directly in how each one feels to use.

The Big Picture

Both Antigravity and Windsurf are full-featured AI IDEs designed to augment developer productivity through intelligent code assistance, agent orchestration, and integrated development environments. However, they represent different philosophies about how AI should integrate into the development workflow.

Antigravity focuses on deep project context awareness and extensible agent frameworks, with a free preview tier that lets developers test core functionality immediately. Windsurf, now backed by Cognition (creator of Devin), emphasizes autonomous agent capabilities and production-grade task delegation, operating on a premium subscription model.

Agent Capabilities Deep Dive

Antigravity's Agent Framework

Antigravity provides an extensible agent architecture accessible through its ADK (Antigravity Development Kit). Agents can:

• Understand project context — Agents maintain awareness of your entire codebase architecture
• Execute multi-step workflows — Coordinate across files with dependency awareness
• Custom agent creation — Build specialized agents for domain-specific tasks
• Plan mode execution — Preview intended actions before agents make changes
• Skill system — Install community-built or custom agent skills

// Custom Antigravity Agent Example
import { Agent } from '@antigravity/adk';
 
const documentationAgent = new Agent({
  name: 'Documentation Generator',
  description: 'Generates API documentation for exported functions',
  actions: [
    'scan-exports',
    'generate-jsdoc',
    'create-markdown',
    'validate-examples'
  ]
});
 
// Use in Antigravity IDE
// > @documentationAgent generate docs for src/api/

Windsurf's Devin-Inspired Agent Design

Windsurf, leveraging Cognition's Devin technology, emphasizes autonomous task execution:

• Autonomous problem solving — Agents work independently on complex tasks
• Command execution — Direct terminal and build system control
• Error recovery — Automatic detection and resolution of build failures
• Dependency management — Agents handle package installations and version conflicts
• Long-running workflows — Agents persist across multiple turns

// Windsurf Agent Task Example
// @windsurf analyze and fix all TypeScript errors in the codebase
 
// The agent:
// 1. Identifies all TypeScript compilation errors
// 2. Analyzes root causes across files
// 3. Applies fixes while maintaining type safety
// 4. Runs tests to verify solutions
// 5. Commits changes with descriptive messages

Model Context Protocol (MCP) Support

Modern AI IDEs increasingly integrate with external services through MCP, a standardized protocol for tool integration.

Antigravity MCP Integration:

• Supports MCP servers for extended functionality
• Agents can invoke MCP tools for specialized operations
• Community-driven MCP server ecosystem
• Configuration through AGENTS.md files
• Local and remote MCP server support

Windsurf MCP Integration:

• Emerging MCP support with Cognition integration
• Focus on high-reliability enterprise connectors
• Deep integration with development infrastructure tools
• Scheduled MCP integration improvements

Multi-Agent Orchestration Patterns

Antigravity's Orchestration Philosophy

Antigravity supports multiple agents working in coordination through Mission Control, a centralized agent coordination layer:

Router Pattern: Different agents handle different request types

// Antigravity Mission Control routes tasks
const taskRouter = {
  'code-review': 'review-agent',
  'test-generation': 'testing-agent',
  'documentation': 'docs-agent'
};

Pipeline Pattern: Sequential agent execution with output transformation

// Agents process task in sequence
// code-generation-agent -> testing-agent -> docs-agent

Parallel Execution: Multiple agents work simultaneously on independent subtasks

// Multi-agent execution
// testing-agent, linting-agent, security-scan-agent run in parallel

Windsurf's Autonomous Coordination

Windsurf's multi-agent approach emphasizes autonomous decision-making:

• Automatic agent selection — Windsurf chooses the best agent for each task component
• Dependency awareness — Agents understand inter-task dependencies
• Self-healing workflows — If one agent fails, others adapt execution
• Progress tracking — Real-time visibility into parallel agent work

Pricing Breakdown (2026 Rates)

How I Split My Work Between Them

The sections above are a general comparison, but let me share how I actually choose between the two after living with both.

I run several small products on my own, and I spend more time keeping things from breaking than writing new code. With that as my baseline, the single most important factor is whether I can stay in control of how much I hand to the agent.

The main reason Antigravity is my daily driver is Plan Mode: it shows me what it intends to do before it does it. I can review the plan, let the safe steps run, and stop only the risky one. In solo development, a single runaway auto-fix can land straight in production, so that small extra step earns its keep.

I reach for Windsurf when the task is an isolated, throwaway job — something like "clear every TypeScript error in this directory," where a failure stays contained. For that kind of work, autonomous execution is simply faster, and the confirmation step just gets in the way.

On cost, the presence of a free preview tier matters a lot for a solo developer. Antigravity lets me try the core features before paying, so "walk away if it does not fit" is an easy call. Windsurf assumes a subscription from the start, which fits people whose team and production workflow are already settled.

My conclusion is simple: Antigravity for the work I want to hold onto, Windsurf for the work I want to hand off. Rather than treating it as either/or, switching tools based on the nature of the task is the more realistic approach for solo development.

Final Verdict

Choose based on your priorities:

• Best for developers valuing control and cost: Antigravity
• Best for enterprises prioritizing autonomy: Windsurf
• Best for startups and learning: Antigravity
• Best for production-critical workflows: Windsurf

Both are strong tools, and the difference is less about better or worse than about temperament. Reach for Antigravity when you value flexibility and cost-effectiveness; reach for Windsurf when you value autonomous capabilities and enterprise support.

If you want a concrete first step, open one of your own everyday repositories in Antigravity's free preview tier and hand it a single small fix in Plan Mode. That one run is usually enough to give you a feel for what to hold onto and what to hand off. Thanks for reading — I hope you find the tool that fits the way you build.
