Why "which one" has no one-line answer
In 2026, the AI IDE landscape is richer than ever. Google Antigravity and Cursor stand out as the two major AI-powered coding tools attracting serious developer attention. But the question remains: which one should you choose?
We'll walk through the differences one by one—features, AI models, agentic capabilities, pricing, and the code quality each one actually produces—so you can see which IDE fits your workflow.
1. Core Specs at a Glance
| Aspect | Antigravity | Cursor |
|---|---|---|
| Developed by | Anysphere | |
| Base Editor | VS Code-based | VS Code-based |
| Primary AI Models | Gemini 3.1 Pro / Flash | GPT-4o / Claude |
| Agentic Framework | AgentKit 2.0 (16 agents) | Cursor Tab + Composer |
| Multi-file Editing | ✅ Full support | ✅ Full support |
| Local Execution | Partial | Cloud-dependent |
| Pricing | Free → Pro (monthly) | Free → Pro (monthly) |
| Offline Capability | Limited | Very limited |
2. AI Model Ecosystems
Antigravity: Gemini-First Integration
Antigravity tightly integrates Google's Gemini family:
- Gemini 3.1 Pro: Latest reasoning, agent-optimized
- Gemini 3.1 Flash: Low latency, cost-effective
- Claude: Optional (via OpenRouter)
- Custom Models: Vertex AI support for on-premises LLMs
// Antigravity Manager Surface orchestrating multiple models
const orchestrator = {
agents: [
{ model: "gemini-3.1-pro", role: "architect" },
{ model: "gemini-3.1-flash", role: "code-reviewer" },
]
};Cursor: Multi-Provider Flexibility
Cursor supports multiple AI providers out of the box:
- OpenAI GPT-4o: Default (recommended)
- Anthropic Claude: Direct integration
- Others: Plugin extensibility
Benefit: Not locked into one vendor. Trade-off: More configuration overhead.
3. Agentic Capabilities: AgentKit vs Cursor Tab
Antigravity: AgentKit 2.0's 16 Specialist Agents
AgentKit 2.0 comes with 16 built-in specialist agents:
# AGENTS.md (Antigravity Example)
agents:
- code-writer: Generates code
- code-reviewer: Quality audits
- test-generator: Auto test generation
- architect: System design
- performance-analyzer: Profiling & optimization
- security-auditor: Vulnerability scanning
- documentation-writer: Auto docs
- refactoring-expert: Code refactoring
- data-analyzer: Data transformation
- (+ 7 more specialized roles)Key Features:
- AGENTS.md text-based definition (Git-friendly)
- Runaway prevention (max_iterations, loop detection)
- Parallel execution support
- Unified Manager Surface orchestration
Cursor: Tab Completion + Composer
- Cursor Tab: Inline AI suggestions (Copilot-style)
- Composer: Multi-file editing (simultaneous file manipulation)
Strengths:
- Minimal learning curve
- Real-time suggestions
- Strong multi-file UX
- Limitation: Less fine-grained orchestration control than AgentKit
4. Multi-File Editing Experience
Antigravity: Agent-Driven Patch Generation
antigravity --mode orchestrate --max-iterations 5
# Output: Auto-generated patches across files
# - src/api.ts (type fixes)
# - src/hooks/useData.ts (logic update)
# - __tests__/api.test.ts (new tests)Benefits:
- Agent-managed safety (runaway prevention)
- Cost control (token budget limits)
- Full audit trail for each step
Cursor: Composer's Live Editing
Cursor Composer > "Update these files"
→ Real-time preview & approval
Benefits:
- Intuitive visual workflow
- Shorter approval loop
- Trade-off: Automation is lower (more manual review)
5. Code Quality Benchmark (Real-World Test)
We implemented the same task—"Firebase Realtime Todo app with React hooks"—in both IDEs:
| Metric | Antigravity | Cursor | Notes |
|---|---|---|---|
| Type Safety | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Antigravity: strict TS by default |
| Test Coverage | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | AgentKit's test-generator agent |
| Performance | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Near parity (Gemini Flash slightly faster) |
| Security Auditing | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | Built-in security-auditor agent |
| Auto-Documentation | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | documentation-writer agent |
| Code Readability | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Tie (personal preference matters) |
6. Extensibility & Integrations
Antigravity: MCP (Model Context Protocol)
Antigravity integrates third-party tools via MCP servers:
antigravity mcp-store
# Available MCPs (March 2026)
- Figma / Design tokens
- Notion / Database queries
- GitHub / Auto PR creation
- Stripe / Billing integration
- Firebase / Realtime sync
- PostgreSQL / SQL generationAdvantage: Declarative, version-controlled integrations.
Cursor: VSCode Extensions
- Access to thousands of extensions
- Community-driven ecosystem
- Rich marketplace
Advantage: Massive plugin ecosystem. Trade-off: Quality varies widely.
7. Pricing Breakdown (March 2026)
Antigravity
- Free: Gemini Flash with limits (10K tokens/month)
- Pro ($15/month): Unlimited Gemini Pro + full AgentKit
- Team ($40/user/month): Team management + private MCP servers
Cursor
- Free: GPT-4o limited (10 uses/month)
- Pro ($20/month): Unlimited GPT-4o + Composer
- Business: Custom pricing for teams
Analysis: Similar pricing, but different value depending on your priorities.
8. Who Should Choose What?
Choose Antigravity If...
✅ You want agentic automation → Multi-agent orchestration for large refactorings
