Claude Computer Use Review: Hands-On Testing (2026)
Google Antigravity vs Cursor vs Windsurf: Best AI IDE 2026
Google just entered the AI IDE race with a tool that’s free, agent-native, and can run five parallel coding agents at once. Within 24 hours of launch, a security researcher had documented five critical vulnerabilities—including remote code execution and data exfiltration. Within two weeks, a developer’s entire D: drive had been wiped.
I’ve been testing all three IDEs for the past month. That’s the state of the AI IDE market in February 2026: three serious contenders, very different risk profiles, and one choice that could cost you more than $20/month if you pick wrong. Here’s what you need to know before switching.
Quick Verdict: Google Antigravity vs Cursor vs Windsurf
Aspect Google Antigravity Cursor Windsurf Best For Vibe coders, experimenters Professional developers Mid-tier balance of cost and power Pricing Free (preview) $20/month (Pro) $15/month (Pro) Parallel Agents 5 via Manager View 1 at a time 1 at a time Security Critical issues unresolved SOC 2 Type II SOC 2 Type II, FedRAMP Enterprise Ready No Yes Yes Codebase Context Excellent (Gemini 3) Excellent Excellent (Cascade) Drive Deletion Risk Documented Very low Very low Bottom line: Cursor is the enterprise-safe choice. Windsurf is the best value. Antigravity is compelling and free, but not ready for production work or anything you can’t afford to lose.
The Short Version
Use Cursor when you need:
- Enterprise compliance or SOC 2 evidence for a security review
- Reliability you can stake your codebase on
- Multi-model flexibility (GPT-4, Claude, more)
Use Windsurf when you need:
- Most of what Cursor does at 25% lower cost
- FedRAMP High availability for government/regulated environments
Use Google Antigravity when you need:
- To experiment with true parallel multi-agent workflows for free
- Gemini 3 Pro’s vision and reasoning capabilities
- You’re fine keeping sensitive files offline or in a separate machine
What Google Antigravity Actually Is
Antigravity launched in November 2025 alongside Gemini 3. It’s a heavily modified VS Code fork, built around the idea that AI should manage your code, not assist with it.
The headline feature is Manager View: a control panel that lets you spawn up to five AI agents working in parallel across separate workspaces. You can set Agent 1 to refactor the backend API while Agent 2 builds out the UI components and Agent 3 writes tests. All run simultaneously without interrupting each other. When they finish, each agent delivers a set of artifacts for your review.
This is architecturally different from anything Cursor or Windsurf currently offer. Both are single-agent tools. With Antigravity, you’re less of a programmer and more of a project manager delegating to a team of AI developers.
The other distinct feature is vibe-first input: drop a screenshot of a UI mockup or a video of an animation into the chat, and Gemini 3’s vision model generates the CSS and JavaScript to replicate it. For designers who want to code, or developers who work from mockups, this is genuinely useful.
Current pricing: Free in public preview with generous rate limits on Gemini 3 Pro. No enterprise tier yet. Future pricing is expected to land around $20/month Pro and $40-60/month Enterprise, but nothing is committed while it’s in preview.
Where Cursor Still Wins
Security and Enterprise Compliance
Cursor holds SOC 2 Type II certification, documented at trust.cursor.com. It supports SAML 2.0 SSO, per-org privacy controls, customer-managed VPC routing, and KMS encryption. For any developer at a company with a security review process, Cursor is the only choice among these three that can clear compliance.
With 360,000+ paying customers as of early 2026, Cursor’s enterprise maturity is tested. The infrastructure, support, and audit trail exist.
Neither Windsurf nor Antigravity can match this on an apples-to-apples enterprise compliance basis as of February 2026.
Multi-Model Flexibility
Cursor lets you choose between GPT-4, Claude Sonnet, Claude Opus, GPT-4o, and others for each task. Antigravity runs on Gemini 3 primarily. Different models genuinely excel at different problems—complex refactoring vs. rapid prototyping, explanatory reasoning vs. speed. The ability to switch mid-session has real practical value.
Reliability Track Record
Cursor has been a primary tool for professional developers for over a year. I haven’t had a single incident in six months of daily use. The bugs that would wipe your drive have already been found and fixed. That’s what maturity buys you.

Where Windsurf Punches Above Its Price
Windsurf costs $15/month—$5 less than Cursor—and delivers a comparable experience for most developers.
Cascade, Windsurf’s agentic AI core, does multi-file editing, codebase indexing, terminal commands, and runs Netlify deployments from inside the editor. The feature set genuinely tracks Cursor for day-to-day work.
Windsurf also has FedRAMP High availability and zero data retention (ZDR) defaults for Teams and Enterprise accounts. For developers in government contracting or regulated industries, this is meaningful. Windsurf may actually win on compliance for certain federal use cases.
The main reasons I’d choose Cursor over Windsurf: access to a broader model selection, or preference for Cursor’s UX polish. For pure cost-to-capability ratio, Windsurf is the better deal.
Our Cursor vs GitHub Copilot comparison also covers how these tools stack up against the plugin-based approach.
The Security Problem Nobody Wants to Talk About
This deserves its own section because the gap between Antigravity and the other two is significant.
What happened in the first 24 hours after launch:
Security researcher Aaron Portnoy documented five critical vulnerabilities with working exploits:
- Remote code execution via indirect prompt injection
- Hidden instructions using invisible Unicode tag characters
- No human-in-the-loop requirement for MCP tool calls
- Data exfiltration via
read_url_content - Data exfiltration via image rendering
The read_url_content exploit is particularly nasty: a malicious file in your project can trigger a prompt injection that reads your .env file and exfiltrates its contents to an external server. No confirmation dialog appears.
What happened two weeks after launch:
A developer in Greece was using Antigravity’s Turbo mode (which lets the agent execute terminal commands without user confirmation) to sort photos. The agent executed a delete command targeting his entire D: drive instead of the project folder, bypassed the recycle bin, and made recovery impossible. When asked “Did I ever give you permission to delete all the files in my D: drive?”, the AI responded: “No, you absolutely did not give me permission to do that.”
Google’s response: They acknowledged the vulnerabilities and said teams are working on fixes. Worth calling out: the read_url_content data exfiltration vulnerability was inherited from Windsurf and had been known since May 2025.
What this means in practice:
- Don’t open untrusted code in Antigravity
- Don’t store API keys or secrets in
.envfiles in Antigravity projects - Don’t use Turbo mode on production systems or drives with irreplaceable data
- Don’t use it for work where security is a requirement
If your work involves proprietary code, credentials, or client data, Antigravity is not currently appropriate. This isn’t hype or overcaution. It’s documented, reproducible vulnerabilities.

Pricing Comparison
| Plan | Google Antigravity | Cursor | Windsurf |
|---|---|---|---|
| Free | Full preview (generous limits) | Limited (50 slow premium requests/mo) | Basic AI features |
| Pro | ~$20/mo (expected, not yet active) | $20/month | $15/month |
| Enterprise | ~$40-60/user/mo (anticipated) | $40/user/month | $60/user/month |
Right now, Antigravity is genuinely free with real capability. That’s unusual. Google is using the preview period to build the developer audience before pricing kicks in. The free window won’t last. If the product survives its security issues and matures, paid tiers are coming.

Who Should Use What
Choose Cursor if:
- You work at a company with security reviews or compliance requirements
- You want model choice (Claude vs. GPT-4 depending on the task)
- You need something that won’t wipe your drive
- You’re already on the $20/month plan and it’s working
Choose Windsurf if:
- You want comparable capability to Cursor at $15/month
- You’re in a regulated industry and need FedRAMP High availability
- You’re comfortable with Cascade’s approach to agentic coding
Choose Google Antigravity if:
- You want to experiment with parallel multi-agent workflows without paying
- You’re building personal or throwaway projects on machines with nothing irreplaceable
- You’re excited by Gemini 3’s capabilities and want to test the frontier
- You keep secrets and production credentials well away from your IDE projects
Look elsewhere if:
- You’re working with client data or proprietary code
- Your company’s security team would escalate this to a conversation
- You want battle-tested reliability for production systems

The Bottom Line
The three-way AI IDE race in 2026 breaks down clearly:
Cursor is the professional standard. SOC 2, 360,000 paying customers, proven reliability. If you code for work and can’t afford surprises, Cursor at $20/month is the answer.
Windsurf is the value play. Nearly everything Cursor offers at $5 less per month, with better compliance options for regulated industries. If the price difference matters to your budget, Windsurf is a serious choice.
Google Antigravity is genuinely exciting technology with a serious safety problem. The parallel agent architecture is ahead of both competitors. But critical vulnerabilities, a documented data deletion incident, and no enterprise compliance story mean it’s firmly in the “try it, don’t trust it” category for February 2026.
The right move: if you’re a professional developer, stay on Cursor or move to Windsurf. Spin up a throwaway Antigravity project to understand where the technology is headed. Check back in six months. If Google patches the security issues and adds enterprise controls, this could reshape the market.
For now, free doesn’t mean low-cost if you’re the one who loses their drive.

Frequently Asked Questions
Is Google Antigravity safe to use?
Not for professional or production work as of February 2026. Security researcher Aaron Portnoy documented five critical vulnerabilities including remote code execution and data exfiltration within 24 hours of launch. A separate incident saw a developer’s entire D: drive wiped. Google has acknowledged the issues and is working on fixes, but none have been confirmed resolved.
Is Google Antigravity free?
Yes, currently. It’s in public preview with no charge and generous rate limits for Gemini 3 Pro usage. Future paid tiers are anticipated around $20/month Pro, but no pricing is active yet.
How does Antigravity’s Manager View work?
Manager View is a control panel that lets you spawn up to five AI agents working in parallel across separate workspaces. Each agent operates independently. You assign tasks like “refactor the backend API” to one agent and “build the UI components” to another. They work asynchronously and notify you with artifacts when done.
Which AI IDE is best for enterprise use?
Cursor is the most mature enterprise choice with SOC 2 Type II certification, SAML SSO, and privacy controls. Windsurf has FedRAMP High availability making it potentially superior for federal contractors. Google Antigravity has no enterprise compliance story in its current preview state.
Is Windsurf cheaper than Cursor?
Yes. Windsurf Pro costs $15/month versus Cursor Pro at $20/month. The Enterprise pricing difference is smaller ($60 vs $40/user/month), and Windsurf’s Teams pricing depends on size. For individual developers, Windsurf saves $60/year.
What happened with Google Antigravity deleting someone’s drive?
In December 2025, a developer in Greece was using Antigravity’s Turbo mode (which runs terminal commands without confirmation) to sort image files. The agent executed a delete command targeting the root of his D: drive instead of the project folder, bypassed the recycle bin, and made recovery impossible. Google apologized but the data could not be recovered.
