Introduction: The Rise of Agentic Development Platforms
In November 2025, the AI coding landscape transformed dramatically with Google's announcement of Antigravity, its new agent-first development platform powered by Gemini 3 Pro. This launch intensified competition with Claude Code, Anthropic's terminal-based autonomous coding assistant that had already captured significant developer mindshare since its February 2025 general availability.
Both tools represent the evolution from simple code completion to agentic development - where AI agents autonomously plan, execute, and verify complex multi-step coding tasks. But they take fundamentally different approaches to achieving this vision.
This comprehensive guide analyzes both platforms across architecture, performance, features, pricing, and use cases to help you choose the right tool for your development workflow.
What is Claude Code?
Overview
Claude Code is Anthropic's terminal-based AI coding assistant, powered by the advanced Claude Sonnet 4.5 model. Unlike traditional AI assistants that require constant human intervention, Claude Code operates autonomously - understanding your codebase, planning multi-step implementations, and executing complex refactors while verifying its own work.
Core Philosophy
Terminal-First Autonomy: Claude Code integrates directly into your local development environment through your terminal, providing deep codebase understanding without requiring you to switch to a web interface or separate IDE.
Deep Reasoning: Built on Claude Sonnet 4.5's superior reasoning capabilities, Claude Code excels at understanding complex codebases, identifying architectural patterns, and making informed decisions about implementation strategies.
Key Differentiators
- Autonomous Task Execution: Describe what you want in natural language, and Claude Code plans and executes multi-step workflows independently
- Checkpoint System: Automatically saves code state before each change; rewind instantly with two taps of Esc or the
/rewindcommand - Subagents: Deploy specialized agents for parallel development (e.g., one agent builds backend API while another creates frontend)
- Background Tasks: Long-running processes like dev servers remain active without blocking other work
- Code Sandboxing: Advanced security with filesystem and network isolation, reducing permission prompts by 84%
Recent Major Updates (2025)
Checkpoint System (Q1 2025): Revolutionary undo/redo that preserves entire development states, not just file changes
Subagents & Parallel Development (Q2 2025): Multiple AI agents working simultaneously on different aspects of your project
Enhanced Sandboxing (Q3 2025): Improved security boundaries for safer autonomous operations
Agent Skills Framework (Q4 2025): Extensible skill system allowing teams to encode workflows and best practices
What is Google Antigravity?
Overview
Google Antigravity is Google's answer to the agentic development revolution, announced November 18, 2025 alongside the Gemini 3 model release. Built as a fork of Visual Studio Code, Antigravity combines a familiar IDE experience with powerful autonomous AI agents.
Core Philosophy
Agent-First Architecture: While maintaining the familiar VS Code interface, Antigravity elevates AI agents to a dedicated surface with direct access to editor, terminal, and browser for end-to-end task verification.
Multi-Modal Development: Leveraging Gemini 3's advanced vision capabilities, Antigravity seamlessly handles code, images, documents, and browser interactions in a unified workflow.
Key Differentiators
- Browser-Based Verification: Agents can launch browsers to test UI changes, verify deployments, and debug visual issues
- VS Code Familiarity: Built on VS Code, reducing learning curve for millions of developers
- Model Flexibility: Generous rate limits on Gemini 3 Pro, plus full support for Claude Sonnet 4.5 and OpenAI models
- Multi-Modal Capabilities: Native handling of images, screenshots, and visual design elements
- Cross-Platform: Available on macOS, Windows, and Linux
