Antigravity vs Cursor 2026: Google's Newcomer vs the AI IDE Champion

In November 2025, Google launched Antigravity — an Agentic IDE released alongside Gemini 3. It directly challenges Cursor’s dominance. Both tools are built on VS Code and both support Claude models, but their design philosophies are fundamentally different.

At a Glance

Dimension	Antigravity	Cursor
Developer	Google	Anysphere
Current Pricing	Free (preview period)	$20/mo (Pro)
Core Model	Gemini 3 Pro + Claude Opus 4.5	Claude Sonnet 4.5 / GPT-5
Agent Architecture	Agent-First (multi-agent parallel)	Composer (primarily single-threaded)
Browser Control	Built-in	Requires MCP
Output Verification	Artifacts	N/A
Maturity	Preview	Production-grade
China Accessibility	Requires proxy	Requires proxy

Pricing Comparison

Antigravity is currently in public preview and completely free for individuals, including access to top-tier models like Gemini 3 Pro, Claude Opus 4.5 (Thinking), and GPT-OSS 120B. Official pricing is expected in 2026, with Pro estimated at around $20/mo.

Cursor Pro is $20/mo with $20 included usage (unlimited usage in Auto mode), or Pro+ at $60/mo, Ultra at $200/mo.

The biggest reason to try Antigravity right now: free access to Claude Opus 4.5 and Gemini 3 Pro — both of which consume significant quota in Cursor.

Agent Architecture Comparison

This is the most critical difference between the two.

Cursor: Composer + Sub-Agents

Cursor’s Agent is primarily “conversation-driven” — you initiate a task, Cursor executes it step by step, and you can insert confirmations along the way. It introduced Sub-agent capabilities in late 2025, enabling parallel sub-tasks, but the overall flow is still controlled by a linear main thread.

Antigravity: Agent-First Architecture

Antigravity puts the Agent front and center, with built-in support for multiple agents simultaneously controlling the editor, terminal, and browser:

• Artifacts: Each task generates reviewable outputs (task lists, implementation plans, screenshots, browser recordings), allowing you to verify logic before the AI writes code
• Built-in Browser: The Agent can directly interact with a browser (open pages, click elements, take screenshots), enabling true end-to-end task execution
• Parallel Execution: Multiple agents work on different tasks simultaneously without blocking each other

Real-world example: Ask Antigravity to build a “login feature,” and it will simultaneously:

• Agent 1: Analyze requirements and generate Artifacts (implementation plan document)
• Agent 2: Write backend JWT API code
• Agent 3: Open a browser to test the API
• After all complete, consolidate the diff and wait for your confirmation

Model Support

Model	Antigravity	Cursor
Gemini 3 Pro	Yes	No
Gemini 3 Flash	Yes	No
Claude Sonnet 4.5	Yes	Yes
Claude Opus 4.5	Yes (with Thinking)	Yes (requires Ultra)
GPT-5	Yes (GPT-OSS 120B)	Yes
Proprietary Model	No	cursor-small (completion)

Antigravity wins with native Gemini 3 series support (Google’s own models) and free Claude Opus access; Cursor wins with its proprietary fast completion model and broader API compatibility.

---

Code Completion

• Cursor Tab: Industry-leading, with multi-line prediction and extremely fast speed (roughly 2x Claude Sonnet speed) — once you get used to it, it’s hard to go back
• Antigravity: Completion experience currently weaker than Cursor; still being optimized during the preview period

If code completion frequency is your primary criterion, Cursor remains the top choice.

---

Maturity and Stability

Cursor has been refined over multiple years, holds SOC 2 certification, and offers comprehensive team collaboration features (shared Rules, centralized billing management).

Antigravity is a preview release from November 2025. The community has already discovered several security vulnerabilities (within 24 hours of launch), and it currently lacks enterprise-grade compliance certifications. For production environments, Antigravity still carries risk.

---

China Accessibility

Both require proxy access, resulting in a comparable experience in China. If you need a China-accessible solution, consider Trae CN or Cline + Volcengine Ark Coding Plan (setup guide).

Who Should Choose Which?

Choose Antigravity if you:

• Want free access to top-tier models like Claude Opus 4.5 + Gemini 3
• Are interested in Agent-First architecture and willing to tolerate preview-stage instability
• Work on full-stack tasks requiring browser interaction (testing, scraping, UI verification)
• Are already in the GCP / Firebase ecosystem, where Google toolchain integration adds value

Choose Cursor if you:

• Need a stable, reliable production-grade tool
• Have high demands for code completion speed
• Require enterprise-level permissions and auditing for team collaboration
• Are already comfortable with the Cursor workflow and don’t want to bear migration costs

---

Using Both: A Combined Strategy

Many developers currently take this approach: Cursor as the primary tool for daily coding, Antigravity for specific agent-heavy tasks (such as automated testing and end-to-end feature development).

Antigravity is free; Cursor is $20/mo — until Antigravity stabilizes, this is the best value combination.
