Quick Verdict
Decision Matrix (March 2026)
- Choose Antigravity if: You want a visual IDE with multi-agent orchestration, built-in browser automation, and free Gemini 3 access during preview
- Choose Claude Code if: You want terminal-first control, deep codebase reasoning, and a proven agent for complex multi-file refactors
- Either works if: You need an AI agent for autonomous coding tasks. Both handle SWE-bench-level problems. The difference is IDE vs terminal.
Antigravity is Google's bet that the IDE itself should become an agent orchestration platform. It ships a Mission Control dashboard where you spawn, monitor, and coordinate multiple AI agents working in parallel across your editor, terminal, and browser.
Claude Code is Anthropic's bet that developers want AI in their existing terminal. No new IDE. No visual dashboard. Just a command-line agent that understands your entire codebase and executes multi-step tasks with explicit approval gates.

Architecture
Antigravity: Agent-First IDE
Antigravity is a heavily modified VS Code fork rebuilt around agent orchestration. Two primary interfaces: the Editor View (standard IDE with AI-powered tab completions and inline commands) and the Manager View (Mission Control for spawning and monitoring multiple agents).
The Agent Manager is the differentiator. You can dispatch five agents to work on five separate tasks simultaneously. Each agent produces Artifacts: plans, results, diffs, and browser recordings. A Google Docs-style commenting system lets you leave feedback on artifacts, and agents incorporate it without stopping execution.
Browser automation works through a Chrome extension that inserts an HTTP server inside the browser. Agents navigate pages, click buttons, fill forms, and verify expected behavior. For frontend development, this closes the loop between writing code and validating it.
Claude Code: Terminal-First Agent
Claude Code runs in your terminal. It reads your project structure, understands file relationships, and executes tasks through shell commands and file edits. Every action requires explicit approval unless you enable auto-accept mode.
The codebase understanding runs deep. Claude Code indexes your project, reads CLAUDE.md files for project-specific instructions, and maintains context across a session. It works with git natively, creates commits, manages branches, and opens PRs.
No GUI overhead. No browser extension. No agent dashboard. The terminal is the interface, and the developer retains full control over what the agent does.
Antigravity: Visual Orchestration
Mission Control dashboard for multiple agents. Built-in browser automation. Artifact tracking with inline comments. Plan-Review-Execute loop with visual feedback.
Claude Code: Terminal Control
Single-agent depth in your shell. Deep codebase understanding via CLAUDE.md. Explicit approval gates. Git-native workflow with no context switching.
Agent Capabilities
Antigravity: Multi-Agent Parallelism
The Agent Manager lets you run multiple agents simultaneously. One agent refactors the API layer while another writes tests and a third updates documentation. Each agent works in its own workspace with independent context.
Plan Mode generates a detailed Plan Artifact before execution. You review the plan, leave comments, and the agent revises before touching code. Fast Mode skips planning for quick fixes. Antigravity scored 72% first-attempt success on a benchmark of 50 real-world tasks, and 76.2% on SWE-bench Verified with Gemini 3 Pro.
Claude Code: Deep Single-Agent Reasoning
Claude Code focuses on depth over breadth. Extended thinking mode lets the model reason through complex problems before acting. The agent understands architectural patterns, naming conventions, and project structure through codebase indexing and CLAUDE.md context files.
Agent Teams (experimental) adds multi-agent coordination. One session acts as team lead, assigning tasks to teammates. Unlike Antigravity's visual dashboard, Agent Teams operates through terminal-based message passing between sessions. Teammates claim tasks from a shared list and communicate directly with each other.
| Agent Feature | Google Antigravity | Claude Code |
|---|---|---|
| Multi-Agent | Agent Manager (visual, built-in) | Agent Teams (experimental, terminal) |
| Planning | Plan Artifact with inline comments | Think/plan commands, extended thinking |
| Browser Testing | Built-in Chrome automation | No (external tools required) |
| Approval Flow | Review artifacts, comment, approve | Per-action approval or auto-accept |
| Context Files | Workspace settings | CLAUDE.md project instructions |
| SWE-bench Verified | 76.2% (Gemini 3 Pro) | 72-76% (Claude Opus 4.5) |
| First-Attempt Success | 72% (50-task benchmark) | ~33% (Anthropic Economic Index) |
| Parallel Workstreams | Yes (multiple concurrent agents) | Yes (Agent Teams, experimental) |
When Antigravity Wins
Free Access During Preview
Zero cost to start. Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS all available on the free tier. No credit card required. Rate limits are generous enough for most evaluation and light usage.
Multi-Agent Orchestration
Dispatch five agents on five tasks simultaneously. The Agent Manager dashboard shows real-time status, artifacts, and pending approval requests. No terminal juggling.
Browser Automation
Agents test web applications directly through Chrome. Write frontend code and validate it without leaving the IDE. The Chrome extension handles navigation, clicks, form fills, and visual verification.
Model Choice
Run Gemini 3 Pro, Claude Sonnet 4.5, or GPT-OSS within the same IDE. Switch models per task. Claude Code is locked to Anthropic's model family.
When Claude Code Wins
Codebase Understanding
Claude Code indexes your full project and reads CLAUDE.md files for project-specific context. It understands naming conventions, architectural patterns, and cross-file dependencies at a level that general-purpose IDE agents don't match.
Terminal-Native Workflow
No new IDE to learn. No context switching. Claude Code lives in your existing terminal alongside git, docker, and your build tools. For developers who live in the shell, this is the natural integration point.
Explicit Control
Every file edit, every command execution requires approval. You see exactly what the agent plans to do before it does it. Antigravity's autonomous agents have caused data loss incidents reported by multiple developers.
Proven Track Record
Claude Code shipped in 2024 and has been through multiple production cycles. Antigravity launched November 2025 and is still in public preview. Maturity matters for production workflows.
Decision Framework
| Priority | Best Choice | Why |
|---|---|---|
| Free AI coding | Antigravity | Free preview with multiple models included |
| Terminal workflow | Claude Code | Native CLI agent, no IDE required |
| Multi-agent tasks | Antigravity | Built-in Agent Manager with visual dashboard |
| Browser testing | Antigravity | Chrome extension for automated web validation |
| Codebase reasoning | Claude Code | Deep indexing, CLAUDE.md context, extended thinking |
| Developer control | Claude Code | Explicit per-action approval gates |
| Model flexibility | Antigravity | Gemini, Claude, and GPT-OSS in one IDE |
| Production maturity | Claude Code | GA since 2024, battle-tested in production |
| Context window | Antigravity | 1M tokens (Gemini 3.1 Pro) vs 200K (Claude) |
| Enterprise/Teams | Both | Antigravity SOC 2 planned, Claude Code has Teams pricing |
If you want a visual agent platform with parallel execution and browser automation, Antigravity is the more ambitious product. If you want a reliable terminal agent with deep codebase understanding and explicit control, Claude Code is the safer choice.

Frequently Asked Questions
Is Google Antigravity free?
Free during public preview with rate limits. Heavy users hit limits within 2-3 hours. Google AI Pro ($19.99/month) unlocks higher limits. Dedicated Antigravity Pro (~$25/month) and Enterprise (~$45/user/month) tiers are expected as the product exits preview.
Can I use Claude models inside Antigravity?
Yes. Antigravity supports Claude Sonnet 4.5 and Claude Opus 4.5 alongside its native Gemini models and GPT-OSS. Third-party model rate limits may be lower than Gemini's native limits on the free tier.
How do Antigravity and Claude Code compare on benchmarks?
Antigravity with Gemini 3 Pro scores 76.2% on SWE-bench Verified. Gemini 3.1 Pro pushes this to 80.6%. Claude Code with Opus 4.5 scores approximately 72-76% depending on configuration. Both tools perform well above the threshold for practical usefulness on real software engineering tasks.
Does Claude Code support multi-agent workflows?
Yes, through Agent Teams (experimental, disabled by default). One session acts as team lead, coordinating teammate sessions that communicate directly with each other. It's terminal-based rather than visual, and requires enabling the CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS flag.
Which tool is better for web development?
Antigravity has an advantage for frontend work due to built-in Chrome browser automation. Agents write code, launch it, and verify functionality in the browser. Claude Code requires separate browser testing setups but excels at backend, infrastructure, and complex refactoring work where terminal access and deep codebase reasoning matter more.
